Abstract

A molecular beam epitaxy system wherein the molybdenum substrate holder and the molybdenum ring which assembles to the substrate holder to hold the wafer are kept in vacuum essentially all the time. Wafers are not pre-mounted to substrate holders, but the wafer mounting step is performed in ultrahigh vacuum after a cassette of wafers has already been loaded and outgassed, under ultrahigh vacuum. Thus, the substrate holder can be outgassed separately at high temperatures, and can remain under high vacuum.
