Abstract

PURPOSE:To offset the loop height of a bonding wire with the thickness of a tab part so as to thin the thickness of a entire semiconductor device by pelleting and bonding the inner structure of a package on the main face of a semiconductor chip. CONSTITUTION:An outer lead part 2C is bent in U shape at the rear side of a resin sealing material 4 and stored within the thickness of a package main body. Accordingly, the thickness of a semiconductor device can be thinned by offsetting the height of a bonding wire 3 with the thickness of a tab part 2, and it can be made thinner by the amount of the thickness that the groove 5 for setting the outer lead part 2C to the bottom of the resin sealing material 4 is provided, and further a soldering part can be secured. And by making small space 6 between the outer lead part 2C and the bottom of the resin sealing material 4, the outer lead part 2C is made to have elasticity, whereby thermal fatigue at the outer lead part 2C can be reduced.

Note that the former wire bonding method is low cost and is often used. However, if the lead frame 2 is placed under the semiconductor chip 1 as in the conventional case because the height of the bonding wire 3 is high, it is difficult to ensure the overall thickness of the package is 0.6 m. In the example package, as shown in FIG. 1, in order to make the package dimensions within O and G nu at the outer lead portion 2C, a predetermined distance is set for fitting the outer lead portion 2C into the lower surface of the resin sealing material 4. By providing a deep groove 5 and fitting the outer lead portion 2C into the groove 5,
The thickness of the entire semiconductor device can be Q, 6 nm. At this time, the outer lead part 2C and the resin sealing material 4
By creating a small gap 6 between the outer lead part 2C and the lower surface of the outer lead part 2C, the outer lead part 2C can be given elastic force and the degree of thermal fatigue of the outer lead part 2C can be reduced. Although the elastic force is slightly reduced, it is also possible to bond the outer lead portion 2C and the lower surface of the resin sealing material 4 with the adhesive 6A or the like.
The tab portion 2A of the lead frame 2 may be firmly fixed to the package body.
Since the corner portions of the semiconductor chip 1 are held, the semiconductor chip 1 will not be destroyed even if stress is applied to the package.
