Silicon (Si) wafers

DESO Technology Limited (Hong Kong) Silicon Wafers

DESO offers a wide range of Silicon (Si) wafers, including Float-Zone Mono-Crystalline Silicon wafers, Test grade (dummy) Silicon wafers, Test grade (dummy) Monnitor wafers, Cz Mono-Crystalline Silicon wafers, epitaxial Silicon wafers, polished Silicon wafers, and etching Silicon wafers.

Silicon wafers manufacturing process steps include crystal pulling, dicing, grinding, chamfering, etching, polishing, cleaning and inspection.

Stringent quality requirements include high purity of Silicon, high surface flatness of the wafer, and absence of impurity contamination. The four critical steps of the manufacturing process encompase polysilicon purification, polysilicon ingot casting, single crystal Si wafer growth, and Si wafer cutting and shaping. Large-size silicon wafers have become the state-of-the-art solution for integrated circuit manufacturers, as they strive to optimize production output in an efficient manner.
