Abstract
A semiconductor device includes a substrate, a buried insulating film formed on the substrate, an SOI layer formed on the buried insulating film, an insulating film formed to extend from a top surface of the SOI layer to the buried insulating film and to divide the SOI layer into a first SOI layer and a second SOI layer isolated from the first SOI layer, an element formed in the first SOI layer, and an electrode having at one end thereof a pad located directly above the second SOI layer, the other end of the electrode being connected to the first SOI layer. A cavity region is formed between the buried insulating film and the substrate directly below the first SOI layer. The portion of the buried insulating film directly below the second SOI layer is at least partially in direct contact with the substrate.
