摘要: A method of fabricating an Emode HIGFET semiconductor device, and the device, is disclosed including epitaxially growing by metal-organic chemical vapor deposition an epitaxial buffer. The buffer includes a layer of short-lifetime gallium arsenide on a gallium arsenide substrate and a layer of aluminum gallium arsenide on the layer of short-lifetime gallium arsenide. The short-lifetime gallium arsenide is grown at a temperature below approximately 550° C. so as to have a lifetime less than approximately 500 picoseconds. A stack of compound semiconductor layers is then epitaxially grown on the layer of aluminum gallium arsenide of the buffer and an Emode field effect transistor is formed in the stack.
