Definitions
- the present invention relates to a silicone adhesive (die bonding agent) for joining a semiconductor pellet to a semiconductor pellet mounting member such as a tab.
- a silicone adhesive die bonding agent
- a semiconductor pellet made of silicon is bonded to a semiconductor pellet mounting member such as a tab, which is a support member thereof, with an adhesive (a die pond agent) such as an epoxy resin or a polyimide resin.
- an adhesive such as an epoxy resin or a polyimide resin.
- the lead frame is electrically connected and these integral parts are sealed with a sealing resin such as an epoxy resin, the silicone adhesive is used in consideration of cracks and other problems caused by the conventional die pond.
- a semiconductor device in which a semiconductor pellet and a tab are adhered to each other (Japanese Patent Laid-Open No. Sho 61-550300 '). This is an attempt to alleviate internal strain caused by the difference in the coefficient of thermal expansion between the semiconductor belt and the tab by using a silicone rubber elastic body.
- Japanese Patent Application Laid-Open No. 61-550300 discloses an addition reaction curing method in which the content of a low-molecular siloxane having a vapor pressure of 10 mmHg or more at 200 ° C is 500 ppm or less.
- the use of a silicone rubber composition is disclosed in Japanese Patent Application Laid-Open No. 2002-60719, in which a cyclic or linear low-molecular compound having 11 to 50 silicon atoms is used. It has been proposed to use an adhesive silicone rubber with a functional siloxane content of 3% by weight or less. Disclosure of the invention
- the reliability of the joining property can be also improved by the method disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 61-550000 and the method disclosed in Japanese Patent Application Laid-Open No. It was found that there was room for improvement.
- An object of the present invention is to solve the drawbacks of the prior art and to provide a silicone adhesive which does not reduce wire bondability and further does not reduce the adhesion between the semiconductor bellet surface and the lead frame and the sealing resin. It is.
- a silicone adhesive composed of a specific addition reaction-curable silicone rubber composition is used as an adhesive for joining a semiconductor bellet and the pellet mounting member. It was found that it was very effective to complete the present invention.
