发明名称 Lead frame and manufacturing method thereof, and semiconductor apparatus and manufacturing method thereof
摘要 The present invention includes a plurality of mounting portions on which a semiconductor element is mounted, a plurality of electrodes to which the semiconductor elements that are mounted on each of the mounting portions are electrically connected, a corner portion which connects the plurality of mounting portions and which has a hanging lead piece that supports the mounting portions and an electrode connection piece that connects the plurality of electrodes, and a half-blanking portion that has a concave portion formed in a thickness direction of the lead frame and a protrusion formed at a position corresponding to the concave portion, and which is covered with a sealing resin material that seals the semiconductor element. A stress-dispersing portion for dispersing stress that arises, when the half-blanking portion is formed, is provided in the corner portion.
