Patent Images
1. A method of forming a thin film field effect transistor (FET) device, comprising:
- etching a single crystal silicon thin film layer on an insulating thin film layer of an silicon-on-insulator (SOI) substrate, wherein the etched single crystal silicon thin film layer is used as a channel;
forming a gate insulating layer on the SOI substrate that has the single crystal silicon channel formed thereon; and
forming a gate electrode, a drain electrode, and a source electrode.
