Epitaxial grade wafers have a single crystalline layer of silicon deposited on the surface. This layer is typically a different resistivity or dopant than the underlying substrate. This is done to provide multiple layers of resistivity and a pure flat surface for device manufacturing.
SVM can provide epitaxial grade wafers from our inventory or can grow custom EPI layers to meet your exact specifications.
Please CONTACT SVM for further information on epitaxial grade wafers (EPI), to place an order or to discuss your current requirements.
