Title: Semiconductor encapsulation and method for producing the same
Inventor: LI MING-SHIUN
IPC: H01L23/28
Filed: 2001-06-14
Granted: 2002-12-01
Abstract: The present invention relates to a semiconductor encapsulation and a method for producing the same. The method comprises forming a ground ring on a tape-type substrate and a plurality of ground vias going through the substrate. The substrate is adhered with a heat sink so that the heat sink and the ground vias are electrically connected, and the semiconductor chip, sequentially through the solder line, the ground pad, part of the ground vias, the heat sink, part of the ground vias, solder bumps and the printed circuit board, form a ground circuit. Since the grounding circuit of the chip includes the body of the heat sink, the semiconductor encapsulation will not form a floating grounding, and will not cause an excessive grounding inductance and resistance. So that the operation functions of the semiconductor chip will not be adversely affected. The semiconductor encapsulation adopts a single layer-type heat sink so that the process is simplified and the operation cost is reduced. Furthermore, the ground ring pad of the semiconductor encapsulation is not formed on the heat sink so that it will not be contaminated by the blackening process of the heat sink, and the bonding between the ground ring pad and the encapsulation sealant will not be affected. As a result, the encapsulation sealant will not form a delamination phenomenon and the quality of production can be ensured. Furthermore, the semiconductor encapsulation does not need to form a plated metal layer on the heat sink such that a poor bonding between the plated metal layer and the solder line or substrate can be avoided, the production operation can be improved, and the production cost can be reduced.
