On August 10, Shanghai Xinshang Microelectronics Technology Co., Ltd. revealed that its self-developed 350nm step-and-repeat projection lithography machine, the AST6200, has successfully undergone full-process workmanship (Note: The term 'workmanship' is retained here as it represents a specific technical nuance that may not have a precise one-to-one translation in English. However, if a more detailed translation is desired, 'manufacturing process' could be considered as an alternative) verification by a premier domestic compound semiconductor customer. This achievement has paved the way for securing substantial repeat purchase orders, marking the official commencement of commercial large-scale deliveries. Tailored specifically for third-generation semiconductor production lines, this equipment adeptly fulfills the lithography process demands across diverse compound substrate types.
