A silicon nitride film and a silicon oxide film are formed on a glass substrate. On the silicon oxide film is formed a thin film transistor T including a source region, a drain region, a channel region having a predetermined channel length, a first GOLD region having an impurity concentration lower than the impurity concentration of the source region, a second GOLD region having an impurity concentration lower than the impurity concentration of the drain region, a gate insulation film, and a gate electrode. The length of an overlapping portion in plane between the gate electrode and the second GOLD region in the direction of the channel length is set longer than the length in the direction of the channel region of an overlapping portion in plane between the gate electrode and the first GOLD region.

摘要:
A field-effect transistor including N−-extension regions, an N+-drain region, an N+-source region and a gate electrode at a surface of a silicon substrate. A sidewall insulating film on one of the side surfaces of the gate electrode partially covers the surface of the N−-extension region, and a sidewall insulating film on the other side surface entirely covers the N−-extension region. Further, a silicon oxide film covers the surface of N−-extension region not covered by the sidewall insulating film. Thereby, resistances of the gate electrode, source region, and drain region can be easily reduced in a transistor having extension regions, which are asymmetrical with respect to the gate electrode.
