Title: Semiconductor device
Inventor: OKINAGA TAKAYUKI
IPC: H01L21/56
Filed: 1995-12-28
Abstract: PURPOSE: To enhance the bonding strength between the resin of a package and the lead even for a semiconductor device mounting a large pellet by providing a first lead traversing one side of a semiconductor pellet toward a bonding pad, and a second lead traversing the extension of one side and facing the bonding pad. CONSTITUTION: Outer leads are arranged on the side of a pellet where the bonding pad is not arranged and the inner leads of the leads 2a are extended along the major surface of the pellet 1 where the circuit is not formed. The forward end 2b thereof is extended over the side of the pellet where bonding pads 7 are arranged. Since the inner lead of the lead 2a is very long, bonding strength can be enhanced significantly between the lead and the package resin 4. Furthermore, even when a large pellet is mounted, delamination can be prevented effectively at the interface of lead when the outer lead is bent, for example.

IPC: H01L21/66
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To notify the generation of abnormality in a production line with high reliability by outputting the number of defects detected extending over a plurality of processes at the same places on the same wafer. SOLUTION: A wafer through each manufacturing process is checked by using a foreign-matter inspection device and an appearance inspection device 202 as required. Inspection data are stored in a data base 203 through a network 205. Inspection data are extracted from the data base 203 and analyzed and processed by an analyzer 204. That is, when the place of a defect in an (n) process and the place of a defect in an (m) process coincide, it is judged to be incoming defects. The processing is conducted regarding all wafer defects in the (n) process, and the number of the coinciding defects is stored as the number of the incoming defects of the water. The processing is performed regarding each wafer. The number of the obtained incoming defects is plotted in order of the processed wafers, and the transition of the number of the incoming defects is displayed. Accordingly, the generation of the abnormality in a production line is notified.

IPC: B43K25/02
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To improve the durability, and provide an appearance having a high class impression without increasing the number of components by forming a clip by a deformation processing of a metal plate, and forming the bent section in such a manner that a vertical cross sectional shape may have a U-shaped approx. uniform curvature, and a lateral cross sectional shape may become an approx. flat plate shape. SOLUTION: A clip 4 is formed in such a manner that after deformation processing a metal by a press working, the metal is cured by a heat treatment, and the main body section L1, the bent section L2 and the attaching section L3 are integrated. Then, for the bent section L2, the vertical cross sectional shape is made an approx. uniform curvature, and a lateral cross sectional shape between them is made a flat plate shape. When the clip 4 is lifted, a stress is properly dispersed without being concentrated, and even when the stress is repeatedly applied, a trouble such as breakage does not occur. The larger the dimension of the bending is, the more obvious the effect is, but in order to prevent the height of the clip 4 from becoming large, the dimension is set at approx. 0.5 to 3 mm, and the plate thickness is set at approx. 0.2 to 1.0 mm.
