Fabrication of micro - and nano-surface structures -- etching

What are metal etching and etching processes?

Etching is a technique that uses chemically strong acid corrosion, mechanical polishing or electrochemical electrolysis to treat the surface of an object. In addition to 

enhancing the aesthetic, it also adds value to the object. From traditional metal processing to high-tech semiconductor manufacturing, etching technology is in the range 

of applications.

What is metal etching?

Metal etching is a technique that removes metal materials by chemical reaction or physical shock. Metal etching technology can be divided into wet etching and dry etching.

Metal etching consists of a series of chemical processes. Different etching agents have different corrosion characteristics and strengths for different metal materials.

Metal etching, also known as photochemical etching, refers to the removal of the protective film of the metal etching area after exposure, platemaking, development, and 

contact with chemical solution in the process ofmetal etching, so as to dissolve corrosion, form convex spots, or hollowed out. The earliest used for manufacturing copper plate, 

zinc plate and other printed concave and convex plate, widely used to reduce the weight of the instrument panel, or processing nameplate and other thin workpiece. After the 

continuous improvement of technology and process equipment, etching technology has been applied to aviation, machinery, chemical,semiconductor manufacturing process, 

electronic thin parts precision metal etching products processing.
