Epitaxial Transistor

[lubbie]

Can anyone explain what these are.. I've found lots of Epitaxial transistors but haven't found any referance to why these are better/worse then a traditional transistor.

Thanks.

Found my answer...


a transistor made by depositing a thin pure layer of semiconductor material (epitaxial layer) onto a crystalline support by epitaxy. The layer acts as one of the electrode regions, usually the collector



Now.. Are they better then any other transistor ????

Epitxial technology is the main technology since decades back. 99.9999% of all transistors are epitaxial...
