Introduction

Lijuan Huang is a prominent inventor based in Tarrytown, NY (US). She has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. Her work focuses on advanced methods for forming strained silicon and silicon-germanium (SiGe) layers, which are crucial for various electronic applications.

Latest Patents

One of her latest patents is titled "Layer transfer of low defect SiGe using an etch-back process." This innovative method describes the formation of strained Si or SiGe on relaxed SiGe on insulator (SGOI) or a SiGe on Si heterostructure. The process involves growing epitaxial SiGe layers on a semiconductor substrate, smoothing surfaces through Chemo-Mechanical Polishing, and bonding two substrates together via thermal treatments. The SiGe layer is then transferred from one substrate to another using highly selective etching, with SiGe itself serving as the etch-stop. The transferred SiGe layer can have its upper surface smoothed for epitaxial deposition of various strained materials, including strained Si, strained SiC, strained Ge, and others, facilitating the creation of electrical contacts for SiGe/Si heterojunction diodes.
