Sulfuric acid (H2SO4, 96% concentration)

It can be used to remove metal and organic matter on the surface of silicon wafer, and also can be used for wet etching and final degumming in photolithography. metal ion <50ppt,particle:0.5um<10、0.3um<20、0.2um<100。

Hubei Xingfu Electronic Materials Co., Ltd

Aluminum etching solution

Aluminum etching solution is composed of several acids mixed according to different ratios, which is the key material of wet etching process to remove Mo Al metal layer on thin film by chemical reaction. Metal ions < 100 ppb.



Hubei Xingfu Electronic Materials Co., Ltd

Tetramethylammonium hydroxide (TMAH, 25% concentration)

Electron grade tetramethylammonium hydroxide has strong alkalinity. 25% aqueous solution is called alkaline developer. It is mainly used to neutralize and peel off organic acids formed after photoresist exposure, leaving unreacted photoresist pattern. Metal ions < 5ppb.



Hubei Xingfu Electronic Materials Co., Ltd

Stripping solution

Stripping solution is composed of several organic solvents mixed according to different ratios, mainly to remove the complete photoresist of etching, so that the pattern protected by photoresist appears. Metal ions < 100 ppb.
