Abstract:
1. A semiconductor device having a Silicon-On-Insulator structure which includes a semiconductor layer formed on an insulator, and having at least one Metal-Oxide-Semiconductor-Field-Effect-Transistor (MOSFET) element, the MOSFET element comprising: a source region; a drain region which is opposed to said source region; a body region disposed between said source region and said drain region; a gate region positioned on or close to a surface of said body region, so as to form an electrically conducting channel in said body region; an extracting region being in contact with both of said body region and said source region, said extracting region having a conductivity type which is the same as a conductivity type of said body region, and having an impurity concentration higher than that of said body region; and a defect layer in which lattice defects are formed, said defect layer being formed in a neighborhood of said extracting region.
