摘要:
The back side of a strip substrate with plural semiconductor chips mounted thereon is vacuum-chucked to a lower mold half of a mold, and in this state the plural semiconductor chips are sealed with resin simultaneously to form a seal member. Thereafter, the strip substrate and the seal member are released from the mold and are cut into plural semiconductor devices. The semiconductor devices thus obtained are improved in their mounting reliability.

The semiconductor device comprises: a tub for supporting a semiconductor chip; a sealing body formed by sealing the semiconductor chip with a resin; a plurality of leads made of a copper alloy, exposed to the back face of the sealing body, and having a soldered layer on the exposed mounted face; and wires for connecting the pads of the semiconductor chip and the corresponding leads. In the manufacture method, the sealing body is polished, after resin-molded, at its back face with a brush to form the two widthwise edge portions, as exposed from the back face of the sealing body, of the lead into rounded faces, and the mounted face of the lead including the rounded faces is protruded at its central portion from the back face of the sealing body thereby to improve the connection reliability at the packaging time.

摘要:
A thermosetting tape is adopted as a dicing tape and, after package dicing, the thermosetting tape is heated, then a desired one of divided CSPs is picked up by an inverting collet. Since the thermosetting tape is heated o a predetermined temperature so that its adhesive force becomes zero, the CSP can be picked up by the inverting collet without peeling it off from the thermosetting tape. Thus, peel-off charging does not occur and therefore it is not necessary to perform a destaticizing process. As a result, it is possible to improve the production efficiency in assembling the semiconductor device (CSP).
