Title: Static induction type thyristor
Inventor: MIYAMOTO YASUNORI
IPC: H01L29/739
Filed: 1986-01-27
Abstract: PURPOSE:To shorten the turn-on time of a static induction type thyristor by forming a gradient of a direction that a density increases at an anode region side in an impurity density of a base region. CONSTITUTION:A thyristor 1 has a P<+> type anode region 2, an N<-> type base region 3, an N<+> type cathode region 5 and a P<+> type gate region 4. An impurity density between A-A' of the thyristor 1 is formed with a gradient in a direction that a density increases at the region 2 side like a curve M. When the impurity density has the gradient, an inner electric field is generated in the region 3 at a breaking state. The direction of the electric field is a direction for accelerating electrons flowing from the region 5 and holes flowing from the region 2. Thus, the start of feeding a main current is advanced to shorten the turn-on time.
