WebOptical lithography: How microchips are made. In simple terms, countless grains of sand turn into microchips in a high-precision process. The key ingredients: light and the projection optics for ZEISS SMT's production of semiconductors. The photolithography used to produced logic and memory chips is a multi-stage process.

WebThe lithography process is a process of exposing photoresist on a wafer by transmitting light through a mask in the shape of a design layout. As the miniaturization of the semiconductor process continues, the pattern of the mask also becomes small, and light passing through a narrow gap forms a photoresist with a distorted shape due to …
