  • Patent number: 10366933
    Abstract: A semiconductor device includes: a base plate; an insulating substrate provided on an upper surface of the base plate; a conductive pattern provided on an upper surface of the insulating substrate; a semiconductor chip mounted on an upper surface of the conductive pattern; a case surrounding the base plate, the insulating substrate, the conductive pattern, and the semiconductor chip; a sealing resin sealing an interior of the case; and an external connection terminal provided to the case. One end portion of the external connection terminal is connected to the conductive pattern, the case has a terminal insertion portion enabling insertion of the other end portion of the external connection terminal in a peripheral wall portion thereof, and a portion of the external connection terminal other than the other end portion is sealed by the sealing resin with the other end portion being inserted in the terminal insertion portion.

  • Patent number: 10319661
    Abstract: In a semiconductor device, an outer peripheral case body has guiding portions formed therein as a plurality of recesses. The plurality of guiding portions each include an upper end opening. The outer peripheral case body has inner peripheral side openings formed in its inner peripheral surface, each of which is continuous with the upper end opening, extends from an upper end face toward a base body and is continuous with the guiding portion. The first insertion portion is inserted into a first guiding portion of the plurality of guiding portions. The first external terminal portion is continuous with the first insertion portion and extends through the upper end opening in the first guiding portion to outside of the outer peripheral case body. The first connection terminal portion is continuous with the first insertion portion and connected to a conductive pattern through the inner peripheral side opening.
