| 20090001508 | Semiconductor device including fuse elements and bonding pad - A semiconductor device includes a lower-layer substrate, a fuse above the lower-layer substrate and blown by radiation with light, a silicon oxide film on the fuse and on an exposed portion of the surface of the lower-layer substrate, and a silicon nitride film on the silicon oxide film. The portion of the silicon oxide film on the surface of the lower-layer substrate is thicker than the fuse, and the silicon oxide film has an opening opposite the fuse. | 01-01-2009 |
| 20100052062 | SEMICONDUCTOR DEVICE, AND MANUFACTURING METHOD THEREOF - To provide a manufacturing method of a semiconductor device which can improve the reliability of the semiconductor device. A first insulating film for covering a semiconductor element formed in a semiconductor substrate is formed by a thermal CVD method or the like which has a good embedding property. A second insulating film is formed to cover the first insulating film by a plasma CVD method which has excellent humidity resistance. A plug is formed to penetrate the first insulating film and the second insulating film. A third insulating film comprised of a low-k film having a relatively low dielectric constant is formed over the second insulating film. A wiring is formed in the third insulating film by a damascene technique to be electrically coupled to the plug. | 03-04-2010 |
