Abstract

In a field effect transistor, an Si layer, an SiC (Si1-yCy) channel layer, a CN gate insulating film made of a carbon nitride layer (CN) and a gate electrode are deposited in this order on an Si substrate. The thickness of the SiC channel layer is set to a value that is less than or equal to the critical thickness so that a dislocation due to a strain does not occur according to the carbon content. A source region and a drain region are formed on opposite sides of the SiC channel layer, and a source electrode and a drain electrode are provided on the source region and the drain region, respectively.
