Abstract: PURPOSE:To enable dry etching without damaging a gate insulating film, by forming, on a substrate, an auxiliary electrode electrically connected with a gate, and eliminating a resist film left on the gate electrode by dry etching. CONSTITUTION:An auxiliary electrode 13c electrically connected with a gate electrode 13b directly or via an insulating film having a thickness nearly equal to a gate insulating film 11a is formed in the other region of the surface of a substrate 10. In this state, a resist film 14b left on the gate electrode 13b is eliminated by dry etching. As a result, the electric potential of the gate electrode 13b becomes almost equal to that of the substrate 10 by the effect of the auxiliary electrode 13c, so that the electric field applied to the gate insulating film 11a at the time of dry etching becomes sufficiently small. Thereby the dry etching of the resist film 14b is enabled without damaging the gate film 11a.
