Filed: 2000-01-28
Abstract: PROBLEM TO BE SOLVED: To suppress pattern defects due to deposits, when patterning a ground layer such as a wiring layer, where a titanium nitride layer is provided at the uppermost part using a hard mask. SOLUTION: A ground layer where the uppermost part, such as a metal lamination film 20 that is composed of a titanium nitride film 12, an aluminum film 13, and a titanium nitride film 14 is composed of the titanium nitride film, and an insulation film such as a silicon oxide film 15 are formed, and a resist pattern 17 is formed on it. Although a deposit 18 that is made of reaction products between titanium and fluorine is generated, when forming the hard mask 17 by patterning the insulation film, washing is made by using washing liquid containing an inorganic acid which contains no fluorine, thus removing a deposit 19 and at the same time, suppressing the generation of a new deposit at the time of washing. Then, when the metal lamination film 20 is etched by the hard mask 17, a metal wiring pattern 19 having few pattern defects can be obtained.

Title: Electrooptical device and projection type display device
Inventor: IIZAKA HIDETO
IPC: G02F1/1368
Filed: 2000-02-09
Abstract: PROBLEM TO BE SOLVED: To provide an electrooptical device capable of performing a display which is bright and whose contrast is high by controlling a direction along which a transverse electric field is generated between adjacent pixels or by restricting areas where its effect reaches and a projection type display device in which the same device is used. SOLUTION: In the reflection type electrooptical device 1, each pixel electrode 9 made of aluminum film has projecting areas 92 projecting in a rectangular plane shape toward adjacent pixel electrodes 9 in X direction. An interelectrode distance GY in a direction (Y direction) orthogonal to the projecting direction (X direction) of the projecting areas 92 is shorter than an interelectrode distance GX in the stretching direction (X direction) of the projecting areas 92. As a result, when the transverse electric field is generated between the adjacent pixels 1A in the X direction, since the traverse electric field acting between the adjacent pixel electrodes 9 in the X direction acts mainly in the Y direction and, also, its effect concentrates at areas where the projecting parts 92 are formed, the effect does not reach the central part of the pixel 9.

Title: Method for manufacturing semiconductor wafer
Inventor: MATAGAWA SATOSHI
IPC: H01L21/304
Filed: 2000-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor wafer where nanotopology is small, flatness is superior, and the amount of polishing in the mirror-surface polishing process of a wafer surface is small. SOLUTION: A lapped wafer is etched by alkali. Therefore, nanotopology appearing on a wafer surface can be reduced, thus suppressing the decrease in a yield in the CMP process. After etching, surface polishing with low damage is executed onto the wafer surface, thus obtaining superior flatness, preventing the decrease in resolution in an exposure process, at the same time reducing the amount of polishing in mirror surface polishing to less than 10 μm, and reducing polishing time. After that, the reverse side of a wafer is polished lightly, thus preventing the roughness of the reverse side of the wafer from being deteriorated by alkali etching. Also, the front and the rear cannot be identified due to light polishing.

Title: Energy absorbing mechanism
Inventor: BAYER FRANZ JOSEF
IPC: F16F13/00
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To increase hardness, and to improve an absorbing characteristic by connecting a communicating tube to a negative pressure source, and connecting an energy absorbing mechanism connected to a valve mechanism capable of setting pressure of an inside space of a bag body to both negative pressure and normal pressure to a collision detecting sensor mechanism. SOLUTION: A large number of granular bodies 3 are sealed as a filler, and an inside space of a flexible bage body 1 is connected to a negative pressure source via a communicating tube 2 and a valve mechanism. An engine intake pipe or an optional thing can be used as a negative pressure source. The valve mechanism connected to a collision detecting sensor mechanism normally puts the bag body 1 and the negative pressure source in a nonconnective state, and while the inside space of the bag body 1 is kept under normal pressure, the inside space of the bag body 1 is set to negative pressure through the communicating tube 2 when detecting a collision in the collision detecting sensor mechanism.  Thus, the bag body 1 tightly sticks to the periphery of the granular bodies 3 being the filler, and since the individual granular bodies 3 are crowded and put in a mutually pushing state, an energy absorbing mechanism can be hardened.
