Abstract
In this work, the fabrication and characteristics of p-type and n-type MODFETs on a relaxed-SiGe buffer was investigated. Record-performance was achieved for the p-type MODFETs. The fabrication of enhancement-mode n-type MODFETs with three different capping layer configurations was also investigated. A novel super-self-aligned process for the fabrication of enhancement-mode MODFETs on uncapped, depleted heterostructures with ion-implanted source and drain was developed.
