TSMC shifts 25% of advanced packaging tool orders to Taiwan

Taiwan Semiconductor Manufacturing Co. Senior Vice President Cliff Hou said Nov. 12 that domestic suppliers now account for 20% to 25% of the company's advanced packaging equipment purchases.

Hou revealed the figure during a keynote speech at the 80th Industrial Day conference in Taipei. The gathering was organized by the Chinese National Federation of Industries.

The procurement share marks the first time local toolmakers have captured a quarter of TSMC's backend machinery spending. The shift reflects efforts to alleviate bottlenecks across chiplet packaging lines.

Advanced packaging combines multiple silicon dies onto a high-density interposer substrate. The architecture allows graphic processing units and high-bandwidth memory to communicate with lower power consumption and higher transmission speeds.

Demand for TSMC's Chip-on-Wafer-on-Substrate technology has surged alongside worldwide orders for artificial intelligence processors. That surge previously stretched delivery lead times for specialized packaging equipment beyond eight months.

The worldwide market for advanced packaging equipment and associated industrial software has reached roughly $50 billion, Hou said. Machinery builders in East Asia have competed aggressively for pieces of that procurement pool.

Taiwanese vendors gained ground primarily in specialized backend categories. Domestic suppliers now manufacture wet etching benches, wafer cleaning units, bake ovens and automated material handling systems used in packaging facilities.

Those tools perform essential chemical washing and wafer transport tasks between lithography steps. Local machinery shops can construct these units at lower capital expense than legacy overseas equipment vendors.

The progress in backend packaging contrasts sharply with front-end wafer fabrication. Taiwanese manufacturers supply less than 1% of the equipment used in TSMC's advanced wafer production cleanrooms, Hou said.

Front-end wafer fabrication requires extreme ultraviolet lithography scanners, complex ion implanters and atomic-layer deposition chambers. Those critical processing categories remain controlled by equipment conglomerates in the United States, Japan and the Netherlands.

Building front-end machinery requires decades of optical research and specialized materials patents. Taiwanese toolmakers chose instead to target backend packaging, where entry barriers were lower and customer production shortages were acute.

Although domestic builders have mastered structural hardware engineering, they face persistent software limitations. Taiwanese packaging machinery continues to lag in equipment automation software, digital interface integration and predictive maintenance algorithms, Hou said.

Modern packaging lines require artificial intelligence models to inspect micro-bump connections and detect microscopic die warpage in real time. Most domestic tools still depend on imported diagnostic software to manage that inspection data.

Buying one-quarter of packaging machinery from domestic vendors provides tangible cost advantages for TSMC. Local purchasing eliminates international shipping tariffs, reduces transport insurance fees and lowers initial capital outlays.

Proximity also accelerates tool commissioning and maintenance cycles. Engineers from domestic suppliers can reach TSMC packaging sites in Taichung, Tainan and Chiayi within two hours to resolve mechanical stoppages.

Rapid servicing helps TSMC keep packaging lines operating at peak capacity. Relying on overseas field engineers often introduced days of downtime during past component failures, slowing scheduled production ramps.

To correct software weaknesses, the Taiwan Semiconductor Industry Association is collaborating with the state-backed Industrial Technology Research Institute. Hou currently serves as chairman of the industry association.

The joint initiative pairs domestic software developers with precision machinery manufacturers. The partnership aims to build standardized software platforms that can link local packaging tools directly to factory automation networks.

The research institute is also assembling a dedicated verification testbed for domestic equipment. The platform allows toolmakers to test prototype machinery on production-grade silicon wafers without disrupting operational foundry lines.

TSMC has not published a breakdown of equipment procurement spending by specific toolmaker, and neither the company nor securities regulators have issued a formal regulatory filing confirming vendor-level contract values.

The industry association and the research institute plan to open their joint equipment verification platform to commercial machinery vendors in the first half of 2027, Hou said.
