Abstract
A semiconductor device and a semiconductor storage device having an SOI structure and being enable sufficient gettering performance without imposing limitations on the freedom of design of an LSI circuit. A semiconductor device includes a semiconductor wafer of SOI structure which has a insulation layer and a silicon layer provided thereon, wherein the semiconductor wafer includes a plurality of element fabrication regions where semiconductor elements are fabricated, and a cutting region provided between the element fabrication regions. Gettering sites are formed in the cutting region by means of embedding a gettering member into grooves of predetermined depth.
