Growth Methods:MOCVD,MBE

epitaxy = growth of film with a crystallographic relationship between film and substrate homoepitaxy (autoepitaxy, isoepitaxy) = film and substrate are same material  heteroepitaxy = film and substrate are different materialsPlease more information of growth methods, please click the following:http://www.powerwaywafer.com/Wafer-Technology.html
