4" Silicon Epitaxial Wafer Top Layer Instrinct Silicon Layer / Phosphorus Doped Layer Ion Implantation Layer Silicon Sub
Silicon epitaxial wafer is a layer of single crystal silicon deposited onto a single crystal silicon wafer(note: it is available to Grow a layer of poly crystalline Silicon layer on top of a highly doped Singly crystalline Silicon wafer, but it needs buffer layer (such as oxide or poly-Si) in between the bulk Si substrate and the top epitaxial layer)
The epitaxial layer can be doped, as it is deposited, to the precise doping concentration while continuing the substrate’s crystalline structure.
Epilayer resistivity: <1 ohm-cm up to 150 ohm-cm
Epilayer thickness: < 1 um up to 150 um
Structure: N/N+, N-/N/N+, N/P/N+, N/N+/P-, N/P/P+, P/P+, P-/P/P+.
Wafer Application: Digital, Linear, Power, MOS, BiCMOS Devices.

What is silicon epi wafer?
Epitaxy is a process in which an additional monocrystalline silicon layer is deposited on to the polished crystal surface of a silicon wafer. This process makes it possible to select the material properties independently of the polished substrate, and consequently to create wafers that have different properties in the substrate and the epitaxial layer. In many cases this is necessary for the semiconductor component’s function.
