Taiwanese foundry (semiconductor contract manufacturing) company TSMC is rapidly securing patents in the field of "silicon photonics," a core technology for next-generation artificial intelligence (AI) chips, as it moves to take the lead in the market. This is seen as a strategy to solidify its position as the world’s number one foundry.
On September 8, local media including Taiwan Economic Daily News, citing Japanese reports, stated that TSMC is significantly increasing its patent applications related to silicon photonics in the United States. The number of applications filed so far this year is more than double that of Intel, marking a sharp increase compared to 2023, when the gap between the two companies was not significant.
