Welcome Shop LED Lights from LED Online store. Here you can buy Silicon Epitaxial Wafer Epitaxy is the process of depositing a thin layer on substrate, Epitaxy layer can be as the same as the basis(Si/Si) or different with the basis (SiGe/Si or SiC/S) ,Silicon epitaxy is a layer of single-crystal silicon on wafer,The epitaxial layer can be doped, as it is deposited, to the precise doping concentration while continuing the substrate's crystalline structure. We can offer Silicon epitaxial wafer and SiGe Epitaxial Wafer,diameter 4", 5", 6", 8". Wafer Type: Blanket Epitaxial Wafer, Patterned Epitaxial Wafer with Burried Layer. Application: Bipolar device, Power MOSFET,IGBT,Detectors and rectifier, IC and As-doped substrate. We supply Silicon Epitaxial wafers to all customers promptly. We can adjust the specification as you need. Silicon Wafer Diameters: 4", 5", 6", 8". 125 mm, 150 mm, 200mm.
