Field of Industrial Application The present invention relates to a resin-sealed semiconductor device in which a heat sink is insulated in a manner such that metal parts other than electrodes do not protrude to the outside. The present invention relates to a so-called fully insulated resin-sealed semiconductor device.

の関係から、該突出部分に別途絶縁保饅材′を塗布する
必要があった。Conventional technology Conventionally, semiconductor devices of the type in which the heat dissipation body is insulated with a sealing resin require molding in addition to electrodes due to the necessity of mold tightening during sealing.
There is a metal wire part that protrudes from the resin part, and care must be taken not to touch the protruding part with other parts when mounting it on an electric circuit.
Furthermore, even when an external heat radiator or the like is attached, it is necessary to separately apply an insulation retaining material to the protruding portion due to the insulation distance.

FIG. In Fig. 1, l is a heat sink;

じめ突出部7とがしめられて位置決めと樹脂もれを防い
でいる。4 is a resin sealing space where the sealing resin is placed, 5 is a mold shed,
6 is the lower mold. The external electrode 9 and the mold retaining protrusion 7 are clamped by the molds 5 and 6 to prevent positioning and resin leakage.

樹脂厚をできるだけ薄く、シかも、均一な厚さにしなけ
ればならない。Here, the reason why not only the external extraction electrode 9 but also the mold-clamping protrusion 7 is required is that insulators have poor thermal conductivity, so in order to improve the heat dissipation performance of the element, it is necessary to use mold-clamping protrusions 7. The resin thickness in the gap 8 between the bottom surface of the enclosed space of the mold 6 and the bottom surface of the heat sink 1 must be made as thin as possible and evenly uniform.
そのためには、高圧で押圧されてくる封止用樹脂に対し

型しめでは不5J能であり、反対側の型じめ用突出7も
必要となる。その結果、型しめ用突出70部分は、第2

してし1い、上記のような不都合を生じる。For this purpose, it is impossible to mold only the external lead electrode 9 to mold the sealing resin that is pressed under high pressure with the target through-hole. 7 is also required. As a result, the molding protrusion 70 portion
As seen in the perspective view of the product shown in the figure, the resin part 1O protrudes slightly, causing the above-mentioned inconvenience.

え、高温に酎える絶縁物の入手難などのため、高価格に
なってしまうという欠点がある。In order to avoid the disadvantage of protruding conductors, it is recommended to insert an insulator τ between the semiconductor element and the heat dissipation body. However, in addition to increasing the number of parts and the number of installation steps, such a method also increases the risk of high temperatures. The drawback is that it is expensive because it is difficult to obtain suitable insulators.

Everything else is the same. That is, the molded part 17 of the heat sink shown in FIG. The molding member 20 is projected into the enclosed space 4, and is supported on the heat radiator 11 by fitting the molding portion 17 of the heat radiator into the heat radiator 11 through the fitting of the peaks and valleys, so that the heat radiator 1it is accurately placed in the enclosed space 4. position. After the resin sealing is completed, the movable mold clamping member 20 is pulled out horizontally, and the sealed product is pushed out of the mold.

It has become. However, since it can be manufactured using the same process as before, high costs are not incurred. And when implementing it in place of conventional products,
There is no need to pay attention to insulation for the protruding portions as in the past, and it is possible to reduce mounting costs and achieve high-density mounting, which can greatly contribute to the miniaturization of devices using this structure.
