The Godfather of South Korea’s Chip Industry

They have been known as “Kim’s Mafia.” Kim Choong-Ki himself wouldn’t have put it that method. But it surely was true what semiconductor engineers in South Korea whispered about his former college students: They have been all over the place.

Beginning within the mid-Nineteen Eighties, as chip manufacturing within the nation accelerated, engineers who had studied below Kim at
Korea Superior Institute of Science and Technology (KAIST) assumed prime posts within the {industry} in addition to coveted positions instructing or researching semiconductors at universities and authorities institutes. By the start of the twenty first century, South Korea had turn into a dominant energy within the international semiconductor market, assembly greater than 60 % of worldwide demand for reminiscence chips alone. Around the globe, a lot of Kim’s protégés have been lauded for his or her good success in remodeling the economic system of a nation that had simply began assembling radio units in 1959 and was fabricating outdated reminiscence chips within the early ’80s.

That success may be traced partly to Kim, now an emeritus professor at KAIST. Of common top, with grey hair since his mid-30s, he was the primary professor in South Korea to systematically train semiconductor engineering. From 1975, when the nation had barely begun producing its first transistors, to 2008, when he retired from instructing, Kim educated greater than 100 college students, successfully creating the primary two generations of South Korean semiconductor consultants.

The Samsung Welfare Basis acknowledged Kim’s affect when it
awarded him its prestigious Ho-Am Prize in 1993 for “constructing a strong basis for Korea’s semiconductor {industry}.” Since then, he has been revered within the South Korean media because the {industry}’s “godfather.” But even immediately, Kim stays largely unknown outdoors of South Korea’s chip neighborhood. Who, then, is that this inconspicuous semiconductor “Mafia” boss?

A Begin in Digicam Chips

Kim Choong-Ki was born in Seoul in 1942, when Korea was a colony of the Japanese Empire. His mom taught elementary faculty; his father, Kim Byung-Woon, was a textile engineer for
Kyungbang, Korea’s iconic producer of yarns and materials. The elder Kim had helped construct the corporate’s first spinning manufacturing unit, and his engineering savvy and consequent renown impressed his son. “He made a day by day tour of the manufacturing unit,” the youthful Kim recollects. “He advised me that he may detect which machines have been in hassle and why, simply by listening to them.” Such classes planted the seed of an ethos that will drive Kim Choong-Ki’s profession—what he got here to name the “engineer’s thoughts.”

Rising up, Kim Choong-Ki was a mannequin South Korean pupil: bookish, obedient, and silent. Though his household pressed him to hitch his father within the textile {industry}, he as a substitute selected to pursue electrical engineering. He studied at Seoul Nationwide College after which at Columbia College, in New York Metropolis, the place he earned his doctorate below
Edward S. Yang, a specialist in transistor idea. Shortly after, in the summertime of 1970, Fairchild Camera and Instrument employed Kim to work in its analysis and improvement laboratory in Palo Alto, Calif.

Since World Conflict II, Fairchild Digicam had been the world’s leading developer of imaging gear, together with radar cameras, radio compasses, and X-ray machines. In 1957, the corporate launched the division Fairchild Semiconductor to manufacture transistors and built-in circuits from silicon, then an progressive transfer, as most semiconductor units on the time used germanium. The enterprise spawned dozens of merchandise, together with the primary silicon built-in circuit, thus fueling the rise of Silicon Valley. As a newcomer to Fairchild’s R&D lab, Kim was put to work on one in all these new sorts of chips: the charge-coupled machine.

Simply the 12 months earlier than, in 1969, George E. Smith and Willard Boyle at Bell Laboratories
proposed the concept of the CCD, for which they might later win a Nobel Prize. But it surely was Kim and his colleagues at Fairchild who realized the primary CCD units that advanced into business merchandise broadly utilized in digital pictures, radiography, and astronomy. Kim turned so proficient in CCD know-how that different engineers on the firm frequently dropped by his workplace on the finish of the day to choose his mind. “Quickly they started to name me Professor CCD,” he remembers.

Amongst different innovations, Kim helped develop a
CCD space picture sensor that drastically improved low-light detection and the primary two-phase CCD linear picture sensor—which, he reported, assured “the benefit of use and the prime quality of picture replica.” “Fairchild’s—or higher name them Choong-Ki’s—CCDs made possible the wide applications in high-resolution cameras,” Columbia’s Yang says. With out these practical units, he provides, “there can be no Nobel Prize for the CCD.”

Kim’s time at Fairchild reworked him as a lot because it did digicam know-how. His education in South Korea and at Columbia had primarily emphasised book studying and idea. However his expertise at Fairchild solidified his perception, first impressed by his father, {that a} true “engineer’s thoughts” requires sensible ability as a lot as theoretical data. Along with performing experiments, he made a behavior of studying inside technical studies and memos that he discovered on the firm library, a few of which he later delivered to KAIST and used as instructing materials.

At Fairchild, Kim additionally discovered learn how to talk with and lead different engineers. When he began there, he was soft-spoken and introverted, however his mentors at Fairchild inspired him to precise himself confidently and clearly. Later, the transformed Kim would turn into the “loudest-speaking” professor at KAIST, based on a number of fellow school members, they usually say his absence made the entire campus appear quiet.

Kim rose shortly inside Fairchild’s hierarchy. However simply 5 years into his tenure, he returned to South Korea. His beloved father had died, and, because the eldest son, he felt a heavy accountability to look after his widowed mom. Racial discrimination he skilled at Fairchild had additionally damage his satisfaction. Most necessary, nevertheless, he had discovered a perfect place to work back home.

Then known as KAIS (the “T” was added in 1981), Kim’s new employer was the primary science and know-how college in South Korea and stays probably the most prestigious. The South Korean authorities had established the institute in 1971 with financing from the US Company for Worldwide Improvement and had invited
Frederick E. Terman, the legendary dean of Stanford College’s faculty of engineering and a “father” of Silicon Valley, to attract up the blueprint for its path. Terman burdened that KAIS ought to intention to “fulfill the wants of Korean {industry} and Korean industrial institutions for extremely educated and progressive specialists, reasonably than so as to add to the world’s retailer of primary data.” It was the proper place for Kim to unfold his newfound philosophy of the “engineer’s thoughts.”

South Korea’s Founding Lab

Kim’s laboratory at KAIS attracted scores of formidable grasp’s and doctoral candidates from nearly the second he arrived within the spring of 1975. The first purpose for the lab’s recognition was apparent: South Korean college students have been hungry to study semiconductors. The federal government touted the significance of those units, as did electronics corporations like GoldStar and Samsung, which wanted them to fabricate their radios, televisions, microwaves, and watches. However the {industry} had but to mass-produce its personal chips past primary built-in circuits reminiscent of CMOS watch chips, largely because of an absence of semiconductor specialists. For 20 years, till the mid-Nineties, becoming a member of Kim’s lab was basically the one method for aspiring semiconductor engineers in South Korea to get hands-on coaching; KAIS was the one college within the nation that had in a position lecturers and correct services, together with clear rooms for assembling high-quality chips.

But it surely wasn’t KAIST’s digital monopoly on semiconductor coaching that made Kim a mentor with out peer. He launched a method of instructing and of mastering engineering that was new to South Korea. As an example, his conviction that an “engineer’s thoughts” requires equal components idea and utility at first puzzled his college students, who regarded engineering as mainly a scholarly self-discipline. Though they have been proficient in arithmetic and properly learn, most of them had by no means carried out any critical work in design and building.

Due to this fact, one of many first classes Kim taught his college students was learn how to use their palms. Earlier than they launched into their very own tasks, he put them to work cleansing the lab, repairing and upgrading gear, and monitoring down essential components. On this method, they discovered learn how to resolve issues for themselves and learn how to improvise in conditions for which no textbook had ready them. Their view of what it means to be an engineer modified profoundly and completely. Lots of them confess they nonetheless repeat Kim’s dicta to this present day. For instance: “Don’t select the themes that others have already thrown into the trash can.” And: “Scientists think about
why first, however we engineers should suppose how first.” And: “Incorrect determination is healthier than sluggish determination.”

Kim’s former college students keep in mind him as type, humorous, nonauthoritarian, meticulous, and hardworking. However in addition they say he was strict and could possibly be scorching tempered and even terrifying, particularly when he thought they have been being lazy or sloppy. Legend has it that a few of his students entered the lab via a ladder from the rooftop to bypass Kim’s office. One in every of his greatest grievances was when college students did not correctly steadiness idea and apply. “Make it your self; then we are going to begin a dialogue,” he scolded those that centered an excessive amount of on mental research. However, he mentioned, “Why don’t you utilize one thing malleable inside the laborious nut in your neck?” as a reproach to those that spent an excessive amount of time constructing issues, implying that they need to additionally use their brains.

Kim influenced not solely his personal college students but additionally numerous others by means of his openness. He cooperated with and even shared laboratory house with different KAIST professors, and he appreciated to go to different departments and universities to present seminars or just to realize new concepts and views—conduct that was, and nonetheless is, very uncommon in South Korean tutorial tradition. In his autobiography,
Chin Dae-Je, who developed 16-megabit DRAM at Samsung in 1989 and later served as South Korea’s minister of data and know-how, recounts looking for out Kim’s tutelage when Chin was a graduate pupil at Seoul Nationwide College within the mid-Nineteen Seventies. “There was an intense spirit of competitors” between SNU and KAIST, recollects Chin, whose alma matter labeled him a “downside pupil” for finding out with a rival professor.

Kim’s collegiality prolonged past academia to {industry} and authorities . Within the early Nineteen Eighties, throughout a sabbatical, he led semiconductor analysis and improvement on the government-funded
Korea Institute of Electronics Expertise, which developed each 32-kilobit and 64-kilobit ROM below his directorship. His well-liked semiconductor workshops at KAIST impressed GoldStar (LG since 1995), Hyundai Electronics (Hynix since 2001), and Samsung to sponsor their very own coaching applications at KAIST within the Nineties. Kim’s shut partnership with these corporations additionally helped launch different pioneering mostly-industry-funded initiatives at KAIST, together with the Middle for Excessive-Efficiency Built-in Techniques and the Built-in-Circuit Design Training Middle, each directed by Kim’s former pupil Kyung Chong-Min. And the semiconductor {industry}, in flip, benefited from the ever extra extremely educated workforce rising from Kim’s orbit.

The Evolution of South Korea’s Semiconductor Business

Kim’s lab at KAIST advanced in parallel with the expansion of the semiconductor sector in South Korea, which may be divided into three durations. In the course of the first interval, starting within the mid-Nineteen Sixties, the federal government led the cost by enacting legal guidelines and drawing up plans for {industry} improvement, establishing analysis institutes, and urgent corporations and universities to pay extra consideration to semiconductor know-how. Samsung and different electronics corporations wouldn’t get critical about manufacturing semiconductor units till the early Nineteen Eighties. So when Kim began his lab, nearly a decade prior, he was coaching engineers to fulfill the {industry}’s
future wants.

His first group of scholars labored totally on the design and fabrication of semiconductors utilizing PMOS, NMOS, and CMOS applied sciences that, whereas not innovative by international requirements, have been fairly superior for the South Korea of the time. As a result of there have been few {industry} jobs, many alumni of Kim’s lab took positions at authorities analysis institutes, the place they developed state-of-the-art experimental chips. An exception was Lim Hyung-Kyu, one in all Kim’s first grasp’s candidates, whom Samsung despatched to check at KAIST in 1976. Lim would go on to guide the event of assorted reminiscence units at Samsung, most significantly NAND flash reminiscence within the Nineties.

The second interval began in 1983, when Samsung declared that it might pursue semiconductors aggressively, beginning with DRAM. The transfer drove rival conglomerates reminiscent of Hyundai and GoldStar to do likewise. In consequence, the South Korean chip {industry} quickly expanded. KAIST and different universities offered the required manpower, and the federal government lowered its function. In Kim’s lab, college students started to discover rising applied sciences—together with polysilicon thin-film transistors (for LCD panels), infrared sensors (for army use), and speedy thermal processing (which elevated effectivity and reduced costs of semiconductor manufacturing)—and printed their ends in prestigious worldwide journals.

KAIST graduates flocked to Samsung, GoldStar/LG, and Hyundai/Hynix. As authorities affect declined, some alums from the primary interval who had labored at authorities analysis institutes additionally took company jobs. On the identical time, increasingly of Kim’s former college students accepted college professorships. After leaving Kim’s lab in 1991, for example, Cho Byung-Jin spent 4 years developing DRAM and flash memory at Hyundai before becoming a star professor at the National University of Singapore and later at KAIST. Kyung Chong-Min, Kim’s first doctoral candidate, joined KAIST’s school in 1983; by the point he retired in 2018, Kyung had educated extra semiconductor specialists than Kim himself.

In the course of the third interval, from 2000 on, {industry} seized the helm of semiconductor improvement. Academia churned out extra specialists in addition to important analysis, with minimal contribution from authorities. Alumni of Kim’s lab continued to guide semiconductor engineering, a few of them rising to turn into high-ranking executives. For instance,
Kwon Oh-Hyun, who acquired his grasp’s diploma from KAIST in 1977, served as CEO at Samsung Electronics for many of the 2010s, when the corporate dominated the world market in not solely reminiscence but additionally cell phones, TVs, and residential home equipment.

Different alums played key roles in semiconductor analysis and improvement. Ha Yong-Min at LG Show mastered TFT-LCD and OLED screens for tablets, pocket book computer systems, and cellphones; Park Sung-Kye, typically known as the “treasure of Hynix,” developed many of the firm’s reminiscence merchandise. In academia, in the meantime, Kim had turn into a mannequin to emulate. Lots of his trainees adopted his strategies and ideas in instructing and mentoring their very own college students to turn into leaders within the subject, making certain a gentle provide of extremely expert semiconductor engineers for generations to come back.

Within the spring of 2007, lower than a 12 months earlier than Kim turned 65—the obligatory retirement age in South Korean academia—KAIST elected him as one in all its first distinguished professors, thus extending his tenure for all times. Moreover the Ho-Am Prize, he has garnered quite a few different awards through the years, together with the Order of Civil Benefit for “excellent meritorious providers…within the curiosity of enhancing residents’ welfare and selling nationwide improvement.” And in 2019, he was named a Individual of Distinguished Service to Science and Expertise, one of many nation’s highest honors.

Legend and Legacy

For younger semiconductor engineers in South Korea immediately, Kim Choong-Ki is a legend—the nice unsung hero behind their nation’s ascendancy in chip manufacturing. However its dominance on this planet market is now below risk. Though South Korea has competed furiously with Taiwan in current many years, its most formidable challenger sooner or later will possible be China, whose formidable
Made in China 2025 plan prioritizes semiconductor improvement. Since 2000, the nation has been a significant importer of South Korean chips. However China’s current heavy funding in semiconductors and the provision of extremely educated Chinese language engineers—together with semiconductor specialists educated in the US, Japan, and South Korea—signifies that Chinese language semiconductor corporations may quickly turn into main international rivals.

Compounding the issue, the South Korean authorities has uncared for its function in supporting chip improvement within the twenty first century. Practically 50 years after Kim started educating its first semiconductor engineers, the {industry} once more faces a big workforce scarcity. Consultants estimate that
a number of thousand new engineering specialists are wanted every year, however the nation produces just a few hundred. But regardless of corporations’ pleas for extra employees and universities’ requires policies that advance tutorial training and analysis, the federal government has finished little.

Towards the top of his profession, Kim had turn into involved with the constraints of the form of “engineer’s thoughts” that had taken root in South Korea. “The financial improvement of Korea was depending on reverse engineering and following superior international locations,” he mentioned in an interview in 1997. That fast-follower strategy, he added, relied on an academic system that taught college students “learn how to learn maps”—to determine a recognized product aim and plot a course for reaching it. “And who made the maps? Superior international locations.” He thus concluded, “We now have to alter our academic coverage and train our college students how to attract maps.”

Kim himself could not have totally realized this formidable imaginative and prescient of cultivating a rustic of creative-minded engineers, able to pioneering really groundbreaking applied sciences that may secure his nation’s management on the world stage. However hopefully his successors have taken his recommendation to coronary heart. The way forward for South Korea is dependent upon it.
