Fabs: The east Asia lesson for India

The authorities transfer comes little greater than every week after Vedanta and Foxconn introduced they’d make investments $19.4 billion in Gujarat to arrange a semiconductor fabrication unit and one other unit to fabricate shows. The semiconductor ‘fab’ unit will manufacture 28 nm chips utilized in shows, autos and different digital merchandise. This follows a string of bulletins by, amongst others, IGSS Ventures of Singapore to construct a fab unit in Tamil Nadu.

The authorities has lengthy mentioned it needs to draw chip producers to India amid a world transfer to ‘de-risk’ chip manufacturing by widening the vary of nations wherein chips are manufactured. During the covid-19 pandemic, lockdowns and delivery issues led to a world scarcity of chips, inflicting a spread of industries depending on chip imports to chop again manufacturing. India’s high carmaker Maruti Suzuki, as an illustration, misplaced gross sales of 270,000 automobiles in unmet bookings throughout 2021-22, its chairman RC Bhargava knowledgeable advised shareholders in its annual report.

India isn’t the one nation making an attempt to incentivize chip makers away from their conventional manufacturing bases akin to Taiwan and South Korea. The US, the European Union, China and Japan have all introduced incentives to draw chip makers to their respective international locations.

Yet, it’s not straight-forward. As it’s, investments wanted for cutting-edge chips from each a value and expertise perspective are huge (see chart 1). On high of that, Moore’s regulation—which says that the variety of transistors on an built-in circuit doubles each two years, boosting computing prowess—is waning. India may plausibly argue it has decrease labour prices, however this counts for little in chip manufacturing (although it turns into extra essential in chip meeting and packaging, that are extra labour-intensive).

The business is a ‘winner-takes-all’ one, with the most important chip corporations being not simply essentially the most technologically refined, but in addition among the many most worthwhile. According to McKinsey, the 5 most-profitable corporations within the business—Samsung, Intel, TSMC, Qualcomm and Apple—have a bigger mixed common annual revenue (of round $35.5 billion) than the opposite 249 corporations within the business.

The many components of the business are additionally geographically dispersed. The US, as an illustration, leads in design of chips, however it’s Taiwan that has over 70% market share in chip manufacturing (chart 2). Taiwan and China dominate the final couple of levels of the worth chain of chip manufacturing and meeting. As McKinsey factors out: “While specialization confers aggressive benefits, it additionally signifies that semiconductor corporations and associated companies are extremely interdependent. Today, no native market or firm has all of the capabilities required for end-to-end semiconductor design and manufacturing.”

But half a century in the past, the world semiconductor business was overwhelmingly dominated by the Americans, each in design and manufacture. How did Taiwan come to dominate the business? Are there any classes for India in at the moment’s day and age?

The Backstory

The hand-wringing over one nation dominating the chip manufacturing business will not be new. Today, it’s Taiwan. In the Seventies, it was Japan. As Terence Tsai and Bor-Shiuan Cheng level out of their e-book Silicon Dragon, a historical past of the high-tech business in Taiwan, by the Nineteen Eighties, Japan had amassed a significant market share within the manufacture of reminiscence chips on the expense of American producers who had dominated the market until then. The writing was already on the wall by the Seventies.

To fight the Japanese ‘threat’, American producers started to maneuver a number of the lower-tech processes within the logic chips worth chain, akin to packaging, offshore to international locations akin to South Korea, Taiwan, Malaysia and Singapore. “The preliminary growth of Taiwan’s semiconductor business was thus just like different Asian international locations, serving as an abroad station for packaging and testing for American and European corporations,” the authors say.

“However, later development was very different,” the authors add. The essential level to notice in regards to the historical past of the Taiwanese chip business is that there was no automated shift up the worth chain from lower-tech to high-tech processes. “In truth, overseas corporations’ funding within the packaging course of in Taiwan didn’t actually assist in growing upward to semiconductor manufacturing, and didn’t contribute to Taiwan’s semiconductor growth as a lot as is often thought.”

It was government intervention, in the form of promoting research, facilitating cooperation and industry linkages that was actually crucial. It set up a research institute—the Industrial Technology Research Institute (ITRI), funded by the national budget—to promote the development of semiconductor technology.

It was ITRI that began a process of technology transfer to the private sector and was instrumental in the setting up of Taiwan Semiconductor (TSMC), which is at the cutting edge of chip manufacturing today.

“To put it another way, foreign companies’ lack of willingness and local enterprises’ lack of ability necessitated government intervention in steering a course for the new industry,” the authors say.

The Taiwanese authorities and personal entrepreneurs collectively determined to play the lengthy sport. By the Nineteen Eighties, Taiwan was already starting to lose its labour price benefit. It was clear that if labour prices alone have been an element, the business was on shaky floor. ITRI performed a key position in importing manufacturing expertise, growing it to the purpose the place it made the processes extra environment friendly, after which transferring that expertise to non-public corporations arrange below its aegis.

The different essential part of Taiwan’s semiconductor technique was the so-called ‘foundry’ mannequin. In this, producers didn’t design their very own chips (or set up their very own manufacturers), however acted solely as outsourced producers for chips designed elsewhere, particularly American corporations. This incentivized American chip corporations to outsource manufacturing to Taiwan, since they didn’t see the latter as providing competitors in chip design.

By the late-Nineteen Nineties, Taiwan had already develop into so dominant in chip manufacturing that an earthquake in September 1999 within the nation induced the share costs of American laptop producers to fall sharply in anticipation of chip provide shortages.

The South Korea Experience

The historical past of how international locations like South Korea and Taiwan turned financial success tales had lengthy puzzled an entire earlier era of economists introduced up on the prevalence of markets over authorities intervention. As John A Mathews and Dong-Sung Cho, of their e-book Tiger Technology, level out: “To anybody conversant in the Korean developmental efforts of the Sixties and Seventies, the thought of neoclassical economists querying whether or not the federal government could make a distinction in financial growth should appear quaint. In Korea the federal government was every thing: it set the objectives for corporations, rationed the finance, disciplined poor performers with monetary stringency and rewarded good performers with monetary largesse. It did every thing besides personal and handle the businesses.”

Like Taiwan, South Korea’s semiconductor industry, too, benefitted from American manufacturers’ concern over Japanese dominance of the memory chip manufacturing market. It was American manufacturers that began outsourcing manufacturing processes to South Korean companies. Significantly, foreign investors in the sector were tight-fisted when it came to technology transfer and intellectual property.

In the early-1980s, for instance, the government and Korea’s industrial conglomerates (called chaebols) were casting around for ways to enter the memory chip market. The US and Japanese firms, though, were unwilling to licence technology to Korean firms—the way the Japanese broke through into that market a decade earlier was a cautionary experience. “For their part, the Japanese understood only too clearly what the Korean aspirations were, and for the most part… declined to assist,” the authors say.

So, Korean engineers who had labored in Silicon Valley have been lured again to Korea, to chaebols seeking to arrange home manufacturing. At the identical time, they started approaching Silicon Valley startups that had good design expertise, however have been starved of capital to fabricate their very own chips. And, just like the Chinese at the moment, there was concern within the US authorities on the time over ‘technology leakage’ to Korean companies, the authors level out.

It was on this manner, by means of the licencing of course of expertise from Japanese agency Sharp (an outsider within the Japanese reminiscence chip business and anxious to make an impression), and licencing of designs from American firm Micron, that Samsung may announce the manufacture of 64K DRAM (dynamic random entry reminiscence) chips in 1983. Crucially, these chips have been on the reducing fringe of expertise on the time.

They have been a showcase of how a rustic with little technological and analysis and growth functionality in a high-tech business until only a decade or two earlier may instantly seem to make a splash. Mathews and Cho level out the principle options of this ‘leverage’ technique: “a concentrate on the absorbing of experience by means of the hiring of engineers, the licensing of product designs and the acquisition of course of expertise from superior companies, providing in trade both money (for cash-starved however expertise wealthy start-ups), or fabrication capability (for companies with out it), or second sourcing and OEM contracts for the established gamers. This was a suitable quid professional quo, it meant that the leverage technique was possible.”

But beyond this, the strategies of the different Korean chaebols—Samsung, Goldstar, Daewoo, Hyundai—to break into the chip market were quite different, with some being more cautious than others. The conglomerates had varying levels of success. By the early-1990s, Samsung’s approach had proven to be superior.

How Governments Helped

Mathews and Cho point out that the common perception—that East Asian governments’ financial support was crucial to the growth of a domestic semiconductor industry—is incorrect. Certainly, financial support was important, but it was not the deciding factor. “Investments in major semiconductor fabrication activities by East Asian firms were financed almost entirely by the companies themselves from external loans, government credit agencies or, in the case of business groups in Korea and Taiwan, from cross-investment by one part of the business group in another. The evidence on this point is incontrovertible… By the stage of high-technology industrialization, companies are sufficiently sophisticated to be able to arrange most of their financing for themselves.”

What was extra essential have been different types of authorities help—public sector analysis and growth institutes akin to ITRI in Taiwan, and the federal government coordination and encouragement of funding within the early levels as in South Korea.

Whether or not international locations like India achieve constructing a long-lasting and sustainable semiconductor manufacturing business might effectively rely upon these different ‘investments’ than within the precise measurement of economic incentives and hand-outs.
