本発明は半導体装置用キャップに関し、1r7fに低融
点の封着ガラスにより気密封止されるセラミックチップ
キャリア(LCC)のキャップKlaする。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cap for a semiconductor device, and relates to a cap for a ceramic chip carrier (LCC) that is hermetically sealed with a sealing glass having a low melting point.

シ小さい平板状のセラミック材が用いられている。Conventionally, for this type of cap, a sealing glass for airtight sealing with the seal pass part of the ceramic case is printed on the sealing part of the cap using a screen printing method, and then is fired and glazed at a temperature below the working temperature. ing. This cap is made of a flat ceramic material that is the same as or one size smaller than the outer edge of the ceramic case.
しかしながら、このようなキャップを使って半導体装置
を封止する際、下記の様な欠点が生じる。However, when such a cap is used to seal a semiconductor device, the following drawbacks occur.

′の状態になシ、半導体装置は正常に気密封止される。To explain this using the cross-sectional view of a conventional semiconductor device shown in FIG. As shown in the figure, a ceramic cap 5 with a sealing glass 4 glazed is placed on a ceramic case 3 to which a semiconductor element 1 is fixed and bonding wires 2 are connected, and the ceramic cap 5 is gradually heated by applying weight with a clip from above. In this way, when the temperature of the sealing glass 4 becomes higher than the working temperature of the sealing glass, the sealing glass 4 melts as shown in figure (b).
′, the semiconductor device is normally hermetically sealed.

部6は極所的に小盲〈なシ、半導体装置の封着強度の劣
化をもたらす原因となっている。At this time, the internal pressure inside the semiconductor device becomes high due to the load, the working temperature, and the higher maximum temperature of the belt furnace. Furthermore, the cuffed sealing glass, which has a low viscosity, flows outward due to the atmospheric pressure inside the semiconductor device, resulting in a 4# state, which is a drawback of the conventional method, as shown in Figure (C). void)
7, and when the internal pressure is high, a through hole is formed in the sealing glass so that gas can pass through the sealing glass and escape to the outside of the semiconductor device. Since the through hole is enlarged and then closed again while the semiconductor device passes through the belt furnace, the airtightness of the semiconductor device is maintained. However, the seal pass portion 6 caused by sealing is partially blind, which causes deterioration of the sealing strength of the semiconductor device.
上記の欠点は、半導体素子にポリイミド等の高分子樹脂
をコーティングした場合には顕著となる。The above-mentioned drawbacks become more noticeable when a semiconductor element is coated with a polymer resin such as polyimide.

うして発生したガスによル、半導体装置内の内圧は増加
し、前記欠点は一層顕著となる。This is because gas is generated from the polymer resin due to heating in the belt furnace during sealing. The resin is heated and sealed in advance, but if this is the case, the polymerization of the resin will re-axis during sealing. Due to the gas generated in this way, the internal pressure within the semiconductor device increases, and the above-mentioned drawback becomes even more noticeable.

The ceramic cap 5 is provided with at least one through hole 8 for discharging gas inside the semiconductor device at a location corresponding to the seal path portion of the ceramic case, and one side of the cap including this location is sealed with a low melting point. Glass 4 is glazed in a ring shape.

It may be installed slightly inside the glazed sealing glass 4. Its position is determined by the flow of the sealing glass] through hole 8

完成する。FIG. 2 is a sectional view of a semiconductor device using the cap of the present invention. That is, when the ceramic cap 5 and the ceramic case 3 are overlapped in the state before sealing (as shown in Figure A1) and passed through a belt furnace, the sealing glass 4 begins to melt when the temperature reaches the sealing operation temperature or higher. After that, the pressure inside the semiconductor device increases due to the maximum temperature of the belt furnace or gas generated by polyimide, etc., and the heating plate is sealed as shown in Figure (b), and the gas melts. The sealing glass 4 is pushed aside, the sealing glass 4 is pushed aside, and the sealing glass 4 is pulled down by the through-hole K to form a section 9, which is discharged to the outside of the semiconductor device through a through hole 8 provided at a location corresponding to the sealing pass section 6. Thereafter, the gas continues to be discharged as the temperature rises, but once the pressure difference between the inside and outside of the gas is alleviated, the sealing glass 4 is moved to the seal pass portion 6 as shown in the figure (c). are uniformly sealed, and the through hole 8 is also sealed to complete hermetic sealing.

ができるので封着強度の安定した半導体装置を得ること
ができる。As explained above, one aspect of the present invention is that by providing a through hole in the low melting point glass sealing part of a cap for a semiconductor device, the air pressure inside the semiconductor device can be suppressed, and the seal pass part can be reduced as the air pressure inside the semiconductor device increases. Since pulling down of the sealing glass can be avoided, a semiconductor device with stable sealing strength can be obtained.
さらに本発明はLCCのキャップに限らず、セラミック
キャップを用いてカラス封着するパッケージ全般に適用
できることはもちろんである。Furthermore, it goes without saying that the present invention is applicable not only to LCC caps but also to any package that is glass-sealed using a ceramic cap.
