Researchers at Zhejiang University in Hangzhou have created China's first commercial electron beam lithography machine. The device, named Xizhi, represents a significant advancement for the country's semiconductor manufacturing sector. Chinese scientists achieved this breakthrough despite facing restrictions on accessing advanced Western lithography equipment from companies like ASML. The machine demonstrates precision capabilities reaching 0.6 nanometers, which approaches the specifications of high-end European tools. However, the technology suffers from severe throughput limitations that prevent commercial viability.

The electron beam approach requires point-by-point wafer processing, which extends production times to several hours per unit. This constraint makes the technology unsuitable for large-scale manufacturing operations. Chinese manufacturers currently depend on deep ultraviolet machines for standard chip production. The new equipment could accelerate research and development efforts while enabling prototype creation of advanced semiconductors. Export controls on electron beam lithography tools previously prevented Chinese access to this technology. The development may reduce the technological gap between Chinese and Western semiconductor capabilities, though substantial differences remain in mass production efficiency.
