Semiconductor Silicon Wafer Prime Grade 3 Inch To 12 Inch
Silicon wafer is a material used for producing semiconductors, which can be found in all types of electronic devices that improve the lives of people. Silicon comes second as the most common element in the universe; it is mostly used as a semiconductor in the technology and electronic sector.
BonTek provide any diameters from 1’’ (25.4 mm) to 12’’ (300 mm) in order to provide the most flexibility as possible. With the aim of providing the largest range of specification, we work either Cz (Czochralski) or FZ (Float Zone) silicon wafers. Furthermore, in order to manufacture qualitative products, pure silicon (9N) raw material is used. The polishing process is also made internally in order to meet or exceed the Semiconductor Equipment and Materials International standards (SEMI).
