Patent number: 8350269Abstract: Disclosed is a method of forming a semiconductor-on-insulator (SOI) structure on bulk semiconductor starting wafer. Parallel semiconductor bodies are formed at the top surface of the wafer. An insulator layer is deposited and recessed. Exposed upper portions of the semiconductor bodies are used as seed material for growing epitaxial layers of semiconductor material laterally over the insulator layer, thereby creating a semiconductor layer. This semiconductor layer can be used to form one or more SOI devices (e.g., single-fin or multi-fin MUGFET, multiple series-connected single-fin, multi-fin MUGFETs). However, placement of SOI device components in and/or on portions of the semiconductor layer should be predetermined to avoid locations which might impact device performance (e.g., placement of any FET gate on a semiconductor fin formed from the semiconductor layer can be predetermined to avoid interfaces between joined epitaxial semiconductor material sections).Type: GrantFiled: April 25, 2012Date of Patent: January 8, 2013Assignee: International Business Machines CorporationInventors: Subramanian S. Iyer, Edward J. Nowak
