Title: Semiconductor device
Inventor: BABA YOSHIAKI
IPC: H01L21/763
Filed: 1989-10-13
Abstract: PURPOSE:To obtain isolation breakdown strength corresponding to the thickness of a side wall oxide film, by forming a cavity (air) part at the bottom part of a trench, and burying a polysilicon film only in the upper part of the trench. CONSTITUTION:A cavity part 26 is formed at the bottom part of a trench 24, and a film 27 composed of a second material (polysilicon) is buried only in the upper part of the trench. As a result, the film 27 composed of the second material is not stuck along the undercut shape at the trench bottom part caused by, e.g. rounding treatment. Hence, as compared with the case where the trench 24 is filled with the film 27 composed of the second material, the electric field concentration at the trench bottom part and the corner part thereof can be restrained. Thereby sufficient isolation breakdown strength corresponding to the thickness of a side wall oxide film 25 in the trench can be obtained.

Title: Pointing device
Inventor: SAKAMOTO HIDETO
IPC: G06F3/0354
Filed: 1993-10-25
Abstract: PURPOSE:To improve the operability and facilitate one maintenance by bringing a material which prevents the entry of rust into contact with the whole part of a ring, supporting a ball in a partially exposed state, which comes into contact with the ball. CONSTITUTION:The material 5 which prevents the entry of dust is brought into contact with the whole part of the ring 3, supporting the ball 2 in the partially exposed state, which comes into contact with the ball 2. Even if dust 7 sticks on the ball 2 when the ball 2 is rotated on a plane, the reverse- directional material prevents the entry of the dust and even if the dust enters the inside, the material 5 which faces from the inside to the outside is forward in grain, so the dust is easily discharged from the inside to the outside. Therefore, even when the dust 7 is present on the plane, the dust never stays by sticking on the ball 2 and entering the ball embedded part and there is no influence on rollers which detect the rotating direction and distance of the ball 2; and the rotating direction and distance of the ball 2 are always detected accurately and inputted.
