樹脂封止金型に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a resin-sealing mold for a semiconductor device that forms an outer shell of the semiconductor device.

る。FIGS. 2(a), 2(b), and 2(c) are cross-sectional views showing an example of a conventional resin-sealed mold for a semiconductor device in order of steps. Conventionally, when molding the outer body of a semiconductor device using this type of semiconductor resin mold, first, the mold shown in FIG.
), after the semiconductor chip 6 mounted on the lead frame 8 is wired with thin metal wires 7, this structure is inserted into the cavity 4 formed by the recess of the upper mold 2b and the lower mold 2b.

装置は製作されていた。Next, as shown in FIG. 2(b), molten resin is injected into the cavity 4 via the runner. Thereafter, the molten resin is hardened to form the outer shell 1. Next, as shown in FIG. 2(c), the mold is opened, and the outer shell 1 is ejected from the lower mold 2b by the ejector 3 and removed from the mold. In subsequent steps, the semiconductor device is manufactured through a lead bending step or a finishing step.

内に取り出すと、樹脂体に内部歪が生し、この樹脂体を
透過する光が内部歪に曲げられ、撮像素子としての機能
が果せないとうい欠点がある。However, with the above-mentioned conventional resin-sealing mold for semiconductor devices, for example, in the case of an image sensor such as a CCD, the resin does not contain a filler, so the mechanical strength after curing is weak, and the mold is difficult to mold. The disadvantage is that the outer shell deforms when removed from the mold and cannot be removed from the mold. Furthermore, if the resin body is taken out before it has hardened, internal distortion will occur in the resin body, and the light passing through this resin body will be bent by the internal distortion, resulting in a disadvantage that it will not be able to function as an image sensor.
本発明の目的は、かかる欠点を解消する半導体装置用樹
脂封止金型を提供することにある。An object of the present invention is to provide a resin-sealing mold for semiconductor devices that eliminates such drawbacks.

体に冷気を吹き付ける冷却機構とを有している。The resin mold for a semiconductor device of the present invention includes an upper mold and a lower mold in which a cavity is formed to form an outer shell of a semiconductor device, an ejector provided on the lower mold and for pushing up the outer shell. The mold has a cooling mechanism that blows cold air onto the outer shell when the mold is opened.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

突き出された外郭体1を冷却する冷却空気5を含き出す
ノズル4を設けたことである。FIG. 1 is a sectional view of a resin-sealing mold for a semiconductor device showing one embodiment of the present invention. As shown in the figure, this resin-sealed mold for a semiconductor device is provided with a nozzle 4 that pumps out cooling air 5 to cool the outer shell 1 projected by the ejector when the mold is opened. .

出来る。Further, this nozzle 4 is attached to the lower mold 2a or the upper mold 2b, and is designed to blow out cooling air every time the mold is opened. Furthermore, Freon or dry nitrogen may be used instead of this cooling air. By doing this, the resin gains a certain degree of strength and the resin itself does not bend, so it can be easily taken out from the mold.
また、樹脂の内部歪もなくなる。Also, internal distortion of the resin is eliminated.
以上説明したように本発明は、半導体装置を樹脂封止後

ノズルを設けることによって、外郭体に内部歪みのない
とともに収り出し易い半導体装置用樹脂封止金型が得ら
れるという効果がある。As explained above, the present invention provides a nozzle that blows out cooling air to rapidly cool the resin outer shell after the semiconductor device is sealed with resin, so that the semiconductor device can be easily stored without internal distortion in the outer shell. This has the effect that a resin-sealed mold for use can be obtained.
