The litography equipment being bought-up (apparently, 90% of the available supply is headed to China) mostly churns out 200 mm wafers, as opposed to today's most modern processes' 300 mm. This means that it's not only the wafer etching machines that are required, but also all the other peripheral equipment that is indispensable to the manufacturing process, such as etching and cleansing machines. This has prompted certain companies, such as Canon, to re-release litography equipment for 200 mm processes - nine years after their last offering was put to sale. This could actually be a way to supplement existing semiconductor requirements, as not everything has to be in the cutting edge of semiconductor capabilities - the old "satisficing" adage could indeed prove a good solution to the increasing demand for semiconductors.

China Gobbling Up Supply of Used Semiconductor Manufacturing Machines
As the tensions between China and the US seem to have come to stay for the foreseeable future, Chinese companies are now opting to resort to older technologies so as to shore up their semiconductor manufacturing capability and reduce dependency from US-based imports. With several companies feeling the tight rope of US-imposed sanctions on their ability to purchase critical supplies (which brought even giant Huawei to its proverbial knees), it seems like a safe bet that China doesn't really care to be on the cutting edge for all but the most mission-critical applications. This happens at a time when the world is still reeling from general semiconductor shortages (some 30% below demand levels). This results in used semiconductor manufacturing equipment - which according to some sources, was "worthless several years ago" - to now be flying from storage warehouses and directly onto factory floors as fast humanly possible. And sometimes, that equipment is acquired for a cool $1 million.The litography equipment being bought-up (apparently, 90% of the available supply is headed to China) mostly churns out 200 mm wafers, as opposed to today's most modern processes' 300 mm.
