METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE
摘要:
A method of manufacturing a semiconductor device for forming an n-type FET has forming an isolation insulating film on a surface of the semiconductor substrate consisting primarily of silicon, the isolation insulating film partitioning a device region of the semiconductor substrate; forming a gate insulating film on the device region of the semiconductor substrate; forming a gate electrode on the gate insulating film; amorphizing regions to be source/drain contact regions adjacent to the gate electrode, of the device region, by ion implanting of one of a carbon cluster ion, a carbon monomer ion and a molecular ion containing carbon into the regions to be the source/drain contact regions; forming an impurity-implanted layer to be the source/drain contact regions by ion implanting at least one of arsenic and phosphorus as an n-type impurity into the amorphized regions; and activating the carbon and the impurity in the impurity-implanted layer by heat treatment.
