Etch (Etch) is a technique for selectively etching the surface of a semiconductor substrate or a surface covering film according to mask patterns or design requirements. It is one of semiconductor manufacturing processes, microelectronic IC manufacturing processes, and micro-nano manufacturing processes Quite an important step. It is a main process of pattern processing related to photolithography. Etching is divided into dry etching and wet etching. Beike Nano currently masters various etching processes, and will design etching solutions with good etching effect and high cost performance according to customer needs.
Etching technology is mainly used in the processing of semiconductor devices, integrated circuit manufacturing, thin film circuits, printed circuits and other fine patterns.
