Abstract
Abstract A semiconductor device includes a package having opposing surfaces, a first terminal for an outer connection supported by said package and electronic components supported by said package, and the opposing surfaces of the package having slits so that a shape of the package can be changed in a mounted state. Therefore, stress applied to soldered junctions of the first and second terminals is decreased.
