Abstract
A wiring formed in the uppermost level of a plastic encapsulated semiconductor device is fixed by connecting it to anchor wirings provided in a lower level via through holes in order to suppress a shear deformation of the uppermost level wiring. The independent wirings are formed in an islandshaped pattern and have no electrical connection to any circuit elements per se.
