Abstract:
1. A resin-encapsulated semiconductor device, comprising: a die pad portion; a semiconductor element mounted on the die pad portion; a plurality of lead portions disposed opposite to the die pad portion; a metal thin wire for connecting a plurality of electrodes of the semiconductor element to the plurality of lead portions; and an encapsulating resin for encapsulating the die pad portion, the semiconductor element, and the plurality of lead portions so that the plurality of lead portions are partially exposed, the plurality of lead portions each including a lead bottom surface part as a bottom surface, a lead outer surface part as a distal end, and a lead upper end part as a part of an upper surface, all of which are exposed from the encapsulating resin, the lead bottom surface part being flush with a bottom surface of the encapsulating resin, the lead bottom surface part and the lead upper end part each including a plated layer, the encapsulating resin being present above the lead upper end part in a vertical direction via a gap portion provided under the encapsulating resin.
