Core Viewpoint - China was one of the earliest countries to produce lithography machines, with significant advancements made in the 1960s and 1970s, showcasing a strong foundation in semiconductor technology that has since been overshadowed by later developments in other countries [2][4]. Group 1 - In the mid-1960s, the Chinese Academy of Sciences developed the 65-type contact lithography machine, marking China's early entry into lithography technology [2]. - By the 1970s, factories like Baoji's 4503 and Shangzhou's 877 were producing advanced semiconductor equipment, including lithography machines that were actively used and well-regarded by research institutions [2]. - The 4503 factory, established during the Third Front Movement, created the first generation of lithography machines, progressively narrowing the gap with international standards [2]. Group 2 - The 877 factory, known for producing integrated circuit chips for satellite control systems, represents a significant historical achievement in China's semiconductor history, although its current state is a reminder of lost potential [4][6]. - In the early 1980s, a shift in policy led to the cancellation of several key projects, including lithography machines, under the rationale that it was better to rent or buy technology rather than develop it domestically [6]. - The abrupt termination of these projects occurred just as Chinese research was on the verge of significant breakthroughs, with advancements in lithography technology that could have positioned China among the global leaders [6].
