Sony is aggressively attacking CIS and placing orders with TSMC Xiong's main factory. With the arrival of the AI wave, CMOS sensors (CIS) are expected to face a new wave of specification updates, and the global CIS leader, Japanese company Sony, is sprinting towards related layouts. Sony has placed a large order at TSMC's new Kumamoto plant in Japan. The industry points out that image sensors are important photosensitive components. CIS, due to its small size, low cost, and higher market share than CCD (photosensitive coupling element), is widely used in multiple fields such as mobile phones, automobiles, security, and medical care.
