摘要
A method for forming a strained silicon layer device with improved wafer throughput and low defect density including providing a silicon substrate; epitaxially growing a first silicon layer using at least one deposition precursor selected from the group consisting of disilane and trisilane; epitaxially growing a step-grade SiGe buffer layer over and contacting the first silicon layer using at least one deposition precursor selected from the group consisting of disilane and trisilane; epitaxially growing a SiGe capping layer over and contacting the step-grade SiGe buffer layer using at least one deposition precursor selected from the group consisting of disilane and trisilane; and, epitaxially growing a second silicon layer using at least one deposition precursor selected from the group consisting of disilane and silane.
