Etching wafer

The etching wafer has the characteristics of low roughness, good glossiness and relatively low cost, and directly substitutes the polished wafer or epitaxial wafer which has relatively high cost to p...

Polished wafer

FZ polished wafers, mainly for the production of silicon rectifier (SR), silicon controlled rectifier (SCR), Giant Transistor (GTR), thyristor (GRO).

Float-zone mono-crystalline silicon wafer

The mono-crystalline silicon with the characteristics of low foreign-material content, low defect density and perfect crystal structure is produced with the float-zone process; no foreign material is...

Czochralski mono-crystalline silicon wafer

The heavily/lightly-doped CZ mono-crystalline silicon is suitable for producing various integrated circuits (IC), diodes, triodes, green-energy solar panel.
