4" Silicon Epitaxial Wafer Substrate Thickness 525 ± 25µm / Resistivity 0.002 - 0.003Ωcm , 2 Epitaxial Layers

PAM-XIAMEN custom epitaxial or EPI wafer services on silicon wafers for research and development or mass production. PAM-XIAMEN processes single crystalline EPI layers on wafer diameters from 50mm to 150mm. Epitaxy is offered on bare wafers or those with buried layers, patterns or advanced device structures. For epitaxial layer deposition, it is important to determine what type EPI layer the application requires before determining how to deposit it. Homoepitaxy is when a crystalline film is grown with the same material as the substrate. Heteroepitaxy is more common, and grows a crystalline film made of a different material than the substrate. Depending on the type epi layer, there are three different ways that they can be deposited. PAM-XIAMEN offers epitaxial wafers with diameters up to 300mm. While 300mm EPI wafers are primarily used in highly integrated semiconductor elements (ICs), smaller diameters are also used for power applications. In order to satisfy the various requirements, substrates and epitaxial layers are designed according to customer specifications.

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.
