After TSMC fab in Japan, superior packaging facility is subsequent


Japan’s efforts to reboot its chip trade are prone to get one other enhance: a sophisticated packaging facility arrange by TSMC. That appears a logical enlargement to TSMC’s $7 billion front-end chip manufacturing fab in-built Kumamoto on Japan’s southern island Kyushu.

In different phrases, a back-end packaging facility will comply with the front-end fab to enrich the chip manufacturing ecosystem in Japan amid issues to diversify semiconductor provide chains past Taiwan as a result of geopolitical tensions. Commerce media has been abuzz about TSMC establishing a sophisticated packaging plant and a brand new Reuters report helps this premise.

Particularly when TSMC has already arrange a sophisticated packaging R&D middle in Ibaraki prefecture, northeast of Tokyo, in 2021. The demand for superior semiconductor packaging has surged as a result of high-end chips serving synthetic intelligence (AI) and high-performance computing (HPC) purposes. The rise of chiplets has additionally introduced superior packaging applied sciences into the limelight.

The above elements name TSMC, the world’s largest semiconductor manufacturing unit, to plan further packaging capability; the truth is, it’s already working to arrange a brand new packaging facility in Chiayi, southern Taiwan. Nevertheless, as TrendForce analyst Joanne Chiao notes, TSMC’s superior packaging facility in Japan will possible be restricted in scale. That’s primarily as a result of most of TSMC’s packaging prospects are based mostly in america.

Determine 1 TSMC’s superior packaging know-how encompasses front-end 3D stacking strategies equivalent to chip-on-wafer (CoW) and wafer-on-wafer (WoW) in addition to back-end packaging applied sciences like built-in fan-out (InFO) and chip-on-wafer-on-substrate (CoWoS). Supply: TSMC

with this new plant, TSMC’s CoWoS packaging know-how shall be transferred to Japan. It’s a 2.5D wafer-level packaging know-how developed by TSMC that permits a number of dies to be built-in on a single substrate, offering greater efficiency and integration density than conventional packaging applied sciences. Presently, TSMC’s CoWoS packaging capability is completely based mostly in Taiwan.

Determine 2 In CoWoS, a number of silicon dies are built-in on a passive silicon interposer, which acts as a communication layer for the lively die on high. Supply: TSMC

On TSMC’s half, the packaging facility in Japan can have nearer entry to the nation’s main semiconductor supplies and tools suppliers and a stable buyer base. TSMC will even benefit from the beneficiant subsidies from the Japanese authorities, which goals to revitalize the native semiconductor trade after dropping floor to South Korea and Taiwan.

Lastly, because the Reuters report notes, no resolution on the size and timeline of constructing the superior packaging facility has been made but. TSMC additionally declined to touch upon this story. Nonetheless, with the development of the TSMC fab in Kumamoto, trade observers firmly imagine that Taiwan’s mega fab will inevitably arrange a sophisticated packaging facility in Japan.
