The Secret Weapon of Tech Giants

• A lead-tin anti-etch layer is pre-plated on the graphic part of the circuit, and then the remaining copper foil is chemically corroded, a process known as etching. The quality requirement for etching is to completely remove all copper layers except those under the anti-etch layer.

 

 

• Etching technology is the core semiconductor manufacturing process second only to photolithography.

From a market perspective, the global production of etching solutions is currently concentrated in Europe, America, Japan, South Korea, and China, with European and American companies holding more than 30% of the global market share; Japan accounts for about 26% of the global share; the combined total of South Korea and China reaches 40%.
