Latest Patents
Murai's latest patents include a semiconductor device and method for fabricating the same. This innovative semiconductor device comprises a semiconductor substrate of a first conductivity type and a pair of spaced diffused layers of a second conductivity type, which is different from the first. A gate electrode is formed on a channel region between the pair of diffused layers, with an intermediate gate oxide layer disposed therebetween. Additionally, a silicon dioxide film covers the upper surface and side surfaces of the gate electrode and the surface portions of the substrate where the diffused layers are formed. A side wall made of polycrystalline silicon is also included, along with an interlayer insulating film that covers the silicon dioxide film, the side wall, and the substrate. A contact hole is formed through the interlayer insulating film to reach one of the diffused layers, exposing part of the side wall within the contact hole, which is then oxidized.
Another notable patent involves a semiconductor device featuring trench-type capacitors. This device includes a silicon substrate, an insulator film formed on the substrate, a transistor provided on the insulator film, and a capacitor formed in a trench within the insulator film. The method of manufacturing this device is also outlined in the patent.
