High voltage deep diode power semiconductor switch

摘要

A semiconductor switch is a lamellar body of semiconductor material having two major opposed surfaces and at least one group of four regions of alternate type conductivity. At least three of the four regions have recrystallized semiconductor material having a solid solubility of metal therein to impart the type conductivity thereto. Each of the first and third regions have the same type conductivity but different levels of impurity concentration. Each of the second and fourth regions have the same type conductivity but different levels of impurity concentration.
