Webepitaxy, the process of growing a crystal of a particular orientation on top of another crystal, where the orientation is determined by the underlying crystal. The creation of various layers in semiconductor wafers, such as those used in integrated circuits, is a typical application for the process. In addition, epitaxy is often used to ...
WebEpitaxy is the growth of a crystalline film suitably oriented onto a substrate: the first advantage in pursuing such a condition is to force the crystal in exposing free surfaces, which are not naturally obtained by cleavage or by conventional bulk growth.
WebIn simple terms. The term epitaxy comes from the Greek roots epi, meaning "above", and taxis, meaning "in ordered manner". It can be translated "to arrange upon". Epitaxy refers to the deposition of an overlayer on a crystalline substrate, where the overlayer is in registry with the substrate.

WebFeb 14, 2019 · What is Epitaxy? Derived from the Greek epi, meaning above, and taxis, an ordered manner, the process results in the formation of one or several crystalline thin films that may be of the same or different chemical compositions and structure as the substrate. The deposited film locks into one or more crystallographic orientations with respect to ...
Epitaxy - Semiconductor Engineering
WebEpitaxy is a method to grow or deposit monocrystalline films on a structure or surface. There are two types of epitaxy-homoepitaxy and heteroepitaxy. Homoepitaxy is a process in which a film is grown on a substrate of the same composition. Heteroepitaxy is a film that is grown on a substrate, which has a different composition.
