Semiconductor device

摘要

Aspects of the invention are directed to a power module including a metal base, an insulating substrate which is attached to the metal base, a semiconductor chip and a control terminal which are attached to a circuit pattern of the insulating substrate, and a resin case which is attached to the metal base. The control terminal can include a penetration portion which penetrates a cover of the resin case, an L-shaped processed portion which is connected to the penetration portion, and a connection portion which is connected to the L-shaped processed portion. A protrusion portion can be installed in a portion of the control terminal, which penetrates the cover. The protrusion portion can be in contact with a protrusion receiving portion which is configured with a front surface of the cover. The L-shaped processed portion can be in contact with a convex portion in a rear surface of the cover.

主权项

1. A semiconductor device comprising:
an insulating substrate; a control terminal which is attached to the insulating substrate to be electrically connected to a semiconductor chip mounted to the insulating substrate; a case which the control terminal penetrates; a first stopping portion which prevents movement of the control terminal in a direction toward the insulating substrate; and a second stopping portion which prevents movement of the control terminal in a direction away from the insulating substrate, wherein the control terminal includes: a penetration portion which penetrates a cover of the case; and an L-shaped member which is connected to the penetration portion to be substantially perpendicular to the penetration portion to form an L shape together with the penetration portion and is in contact with a rear surface of the cover of the case, wherein the control terminal includes a protrusion portion which is installed in the penetration portion and is in contact with a front surface of the cover of the case, wherein the first stopping portion is the protrusion portion, and wherein the second stopping portion is the L-shaped member; wherein the control terminal further includes a connection portion of which one end is connected to a bottom surface portion of the L-shaped member and of which another end is attached to the insulating substrate, with the connection portion having a straight shape, wherein a side surface of the L-shaped member is substantially perpendicular to a side surface of the penetration portion, wherein a side surface of the connection portion is substantially perpendicular to the side surface of the L-shaped member and is substantially parallel to the side surface of the penetration portion, and wherein the protrusion portion is formed with the side surface of the penetration portion.
