Abstract: A new glass lining application method enables stable, uniform glass lining layers to be applied to large glass-lined instruments composed of a stainless base material, the method including forming a thermal spray treatment layer by applying a thermal spray treatment to a surface of a stainless base material using a thermal spray material selected from a group composed of a stainless material identical to the base material, Ni metal, Cr metal, Fe metal, Co metal, Ni—Cr alloys, and Fe—Cr alloys, then forming a glass lining layer on the thermal spray treatment layer by means of a glass lining heat treatment using a ground coat and a cover coat, a surface roughness Rz of the thermal spray treatment layer being within a range from 5 to 100 &mgr;m, and an open pore diameter being within a range from 3 to 60 &mgr;m.

Abstract: A metal-insulator-semiconductor transistor comprises an insulator layer, a semiconductor body provided on the insulator layer and comprising a source region, a drain region and a channel region extending in a first direction between and interconnecting the source region and the drain region, a gate insulator film provided on the semiconductor body so as to cover the channel region except for the part of the channel region in contact with the insulator layer, and a gate electrode of a conductive material provided in contact with the gate insulator film so as to cover the channel region underneath the gate insulator film except for the part of the channel region in contact with the insulator layer. The channel region has a width substantially smaller than twice the maximum extension of the depletion region formed in the channel region.
