Semiconductor integrated circuit device comprising a dielectric isolation structure.

摘要

A semiconductor integrated circuit has a multilayered supporter (2, 22, 23) and one or more semiconductor islands (1) being disposed on the supporter (2, 22, 23) and being insulated against it by an insulating film (21). Within the islands (1), circuit elements are formed. The circuit further comprises an auxiliary electrode (33) provided at the supporter (2, 22, 23).
