Title: Power semiconductor element
Inventor: KOGA TAKEHARU
IPC: H01L27/08
Filed: 1993-03-26
Abstract: PURPOSE:To ensure the stable breakdown strength of the title semiconductor element by the minimum area of a guard ring region by a method wherein the interval between a guard ring layer at the outermost circumference and a channel stopper layer in the edge part of a semiconductor substrate is set to a half or higher of the interval between a layer coming into contact with a main electrode and the channel stopper layer. CONSTITUTION:An experiment in which the number of stages of guard rings and the interval between a guard ring layer 32 at the outermost circumference and a channel stopper layer 4 are changed is carried out. As a result, it is found out that the breakdown strength of the title semiconductor element can be ensured stably when intervals l1, l2, between the p-layer 32 and the p-layer 4 are set to a half or higher of distances W1, W2 between the p-layer 2 coming into contact with a main electrode and the channel stopper 4. In addition, when the l2 is by 50mum larger than l1 in the arc part of a contour, the concentration of an electric field in the arc part of a chip can be reduced. When l1=l2, the ratio of a dielectric breakdown in a linear part is increased. Thereby, when the l2 is made larger than the l1, the concentration of the electric field can be reduced, an increase in a leakage current is prevented, an avalanche breakdown is prevented and the breakdown strength of the title semiconductor element can be enhanced.
