SEMICONDUCTOR DEVICE

摘要

An electrode includes an extending portion extending such that both ends thereof get into a first recessed portion and a second recessed portion provided in a first inner wall and a second inner wall, respectively, facing each other in a lateral direction of a case. The extent to which both the ends of the extending portion get into is set such that positions of both the ends thereof in a case where both the ends are narrowed toward a midpoint therebetween to reduce a length of the extending portion to 70% of the length of the extending portion exist between positions of the first and second inner walls in a case where the first and second inner walls are each narrowed toward a midpoint therebetween by 10% of the distance between the first and second inner walls.

主权项

1. A semiconductor device, comprising:
a substrate on which a semiconductor element is mounted; an electrode that is electrically connected to said semiconductor element; and a case that covers said substrate and a remaining portion except for an upper portion of said electrode, wherein said remaining portion of said electrode includes an extending portion extending such that both ends thereof get into a first recessed portion and a second recessed portion provided in a first inner wall and a second inner wall, respectively, facing each other in a lateral direction of said case, and the extent to which said both ends of said extending portion get into is set such that positions of said both ends thereof in a case where said both ends are narrowed toward a midpoint therebetween to reduce a length of said extending portion to 70% of the length of said extending portion exist between positions of said first and second inner walls in a case where said first and second inner walls are each narrowed toward a midpoint therebetween by 10% of the distance between said first and second inner walls.
