The specific composition of expitaxial wafers enable extraordinary quality. Therefore, epitaxial wafers are mostly used for discrete applications as well as for advanced and highly integrated semiconductor devices.

Epitaxial wafers are made from polished substrates growing a monocrystalline silicon layer on top of the a polished surface.

Siltronic offers epitaxial wafers with diameters from 125 to 300 mm. Tailored substrate and epitaxial layer characteristics are available to meet various application.
