Abstract
Transistor devices comprise a gate electrode, a channel region formed beneath the gate electrode, a source region in contact with one side of the channel region, a first conductive region formed in a semiconductor layer at the outer side of the source region and made of a metal or metal compound, a drain region formed in contact with the other side of the channel region, and a second conductive region formed in the semiconductor layer at the outer side of the drain region and consisting of a metal or a metal compound. The transistor has an SOI structure which has an improved breakdown voltage between the source region and the drain region with low sheet resistances of the source and drain regions. Methods for making the transistor devices are also described.
