On July 14 (local time), Tower Semiconductor witnessed a remarkable surge of over 19% in its stock price, outpacing other stocks within the optical communication sector. Notably, AXT Inc, Applied Optoelectronics, and several other companies also experienced upward trends. On this same day, Tower Semiconductor made a significant announcement: the initiation of a dual-track expansion strategy in Japan. This strategic move involves a comprehensive upgrade of its 300mm silicon photonics, silicon-germanium processes, and advanced packaging capabilities. The primary objective of this expansion is to cater to the long-term demands of global customers, substantially enhance production capacity, and reinforce its technological dominance in the high-end optical semiconductor market. The initial phase of the project is anticipated to achieve full-scale mass production by the fourth quarter of 2027. Furthermore, plans are underway to construct a new 300mm wafer fabrication facility, aimed at further bolstering capacities in silicon photonics and silicon-germanium, thereby meeting the escalating needs of AI data centers and high-speed optical interconnects.
