Chinese Startup Prinano Bypasses DUV Constraints with Nanoimprint Photonic Chips

Prinano Validates 8 Inch Photonic Chip Fabrication Using Nanoimprint Lithography to Bypass ASML Equipment and Strengthen China Domestic Semiconductor Supply Chain

Prinano , a Chinese startup specializing in semiconductor equipment, has announced that they have successfully validated a process for fabricating photonic chips on 8 inch silicon wafers without using traditional deep ultraviolet lithography machines. The South China Morning Post reports that this method completely bypasses the need for expensive, optically based projection equipment from Dutch company ASML that is currently restricted under international export controls. Prinano is based in Hangzhou and partnered with Shenzhen Litra Technology for this fabrication process.
