On June 5, Puyi Technology announced that the company and Shenzhen are working together to achieve a breakthrough in mass production of 8-inch optical chips using vacuum pneumatic nanoimprinting solutions: Relying on the PL-AS vacuum pneumatic wafer-level nanoimprinting lithography equipment independently developed by Puyi Technology, with the customized double-layer imprinting adhesive material system and core process, it completely bypasses the deep UV lithography route, and successfully achieved large-scale mass production of 8-inch optical chip wafers, and reduced chip manufacturing costs to one-tenth of the traditional DUV solution. Among A-shares, the main concept stocks related to nanoimprinting include Sudavig, Medicai, Lihexing, Jingfang Technology, Jinghua Laser, and Crystal Optoelectronics.
