Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: (a) providing a lead frame including: (b) after the step (a), sealing the semiconductor chip with sealing resin by supplying the sealing resin to the device forming portion via a first region of the frame portion in which the through hole is formed in plan view, thereby forming a sealing body sealing the device forming portion and the first region of the frame portion; and (c) after the step (b), removing a first part of the sealing body located at the first region of the frame portion from the lead frame by inserting a pin into the through hole, wherein in plan view, the through hole has a pair of sides that extend divergently from a first end portion of the through hole toward an arcuate second end portion of the through hole such that the first end portion is located closer than the arcuate second end portion to the device forming portion.
