Abstract
A semiconductor rectifier device including an inner layer of semiconductor material of a first conductivity type and an outer layer of first conductivity type but having a higher doping concentration than the inner layer with the outer layer formed with a plurality of islands of opposite conductivity type which do not extend completely through the outer layer so as to provide a semiconductor rectifier device which has greatly improved resistance to high voltage breakdown particularly in the reverse direction.
