12" Dummy Grade / Mechanical Grade Silicon Wafer DSP Thickness 650-700/700-750/750μm No Scratch Films Etch Patterns
PAM-XIAMEN develops advanced crystal growth and epitaxy technologies, range from the silicon substrate to compound semiconductor, PAM-XIAMEN offer semiconductor silicon substrate with diameters from 1’’ (25.4 mm) to 12’’ (300 mm). We work either Cz (Czochralski) or FZ (Float Zone) silicon substrate. The polishing process is also made according to SEMI standard( the Semiconductor Equipment and Materials International standards). We also work ultra thin wafer, silicon oxide wafer SiO2 thin film, silicon nitride wafer Si3N4 thin film, metallization on silicon substrate, and epi wafer service.

What is a Silicon Wafer?
Silicon wafer is the most common semiconductor and the most widely used in the electronic and technology sector, which is a key component in integrated circuits, during the growth process intentional additions of dopants can be added to the to change the purity of the silicon depending on what the purpose of it will be, boron, aluminum, nitrogen, gallium and indium are common silicon dopants. Depending on what level the silicon has been doped, the semiconductor can be considered extrinsic or degenerate. Extrinsic would be lightly to moderately doped whereas degenerate semiconductors act more as conductors because of the high levels of doping that occurs during the fabrication.
PAM-XIAMEN can offer you technology and wafer support, for more information, please visit our website: https://www.powerwaywafer.com,

Quality is our first priority. PAM-XIAMEN has been ISO9001:2008, owns and shares four modern facories which can provide quite a big range of qualified products to meet different needs of our customers, and every order has to be handled through our rigorous quality system. Test report is provided for each shipment, and each wafer are warranty.Before 1990, we are stated owned condensed matter physics research center. In 1990, center launched Xiamen Powerway Advanced Material Co., Ltd (PAM-XIAMEN), now it is a leading manufacturer of compound semiconductor material in China.
