epitaxial layer

[‚ep·ə′tak·sē·əl ‚lā·ər]
(solid-state physics)
A semiconductor layer having the same crystalline orientation as the substrate on which it is grown.

epitaxial layer

In chip making, a semiconductor layer that is created on top of the silicon base rather than below it. See molecular beam epitaxy.
