Title: Semiconductor device and manufacture thereof
Inventor: UEMOTO TSUTOMU
IPC: H01L29/786
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device of CMOS configuration, together with a method for manufacturing it, wherein a desired threshold voltage is set for stable circuit operation. SOLUTION: Related to a semiconductor device comprising p-type and n-type TFTs, a different impurity concentration is separately set for a channel layer of p-type TFT and that of n-type TFT. Thus, the threshold voltages of p-type TFT and n-type TFT come to be optimum values, respectively. A device like this is provided by performing ion-implantation, for example of boron, with an amorphous silicon film 3, and then patterning to form island-like semiconductor films 4a and 4b, and selectively implanting, for example, boron or phosphorous into either of them.

Title: Resist material
Inventor: KASAMA KUNIHIKO
IPC: G03F7/039
Filed: 1991-10-31
Abstract: PURPOSE:To provide a resist material capable of preventing the lowering of dimensional controllability of a chemical amplification system resist near the resolution limits and the generation of resist scums. CONSTITUTION:An organic material which acts as a base on acid formed by an acid generating agent, such as aniline, pyridine, imidazole or ammonium derivatives is added to the conventional chemical amplification system resist by a trace quantity or on the order of mu mole/gr. to constitute a resist material. That is to say, when the conventional resist is given photoirradiation through a mask pattern, the concentration distribution like that as shown in the figure (a) is obtained. When a trace quantity of basic organic substances is added to the conventional resist as shown in the figure (b), the distribution of the difference between the acid concentration and the base concentration is obtained as shown in the figure (c). Even if light contrast of the mask pattern near the resolution limits is lowered, since the acid concentration distribution in a mask edge part is made steep, dimensional controllability is improved. Further, since acid formed in the mask light shielding part by light interference is completely neutralized by a basic material, a problem of resist scums is dissolved.

Patent JP-H04162213-A (JP)
Title: Magnetic recording medium inspection device
Inventor: ITAYA MASARU
IPC: G11B5/84
Filed: 1990-10-26
Abstract: PURPOSE:To prevent thermal harm and the variation of the amount of light, and to enable detection having high sensitivity by using a light-emitting diode having a wavelength of 600nm-1000nm as a light source and irradiating the upper section of a magnetic recording medium with light from the light source while inspecting the state of coating by light transmitted through the magnetic recording medium. CONSTITUTION:When a light-emitting diode 5 having a wavelength of 600nm-1000nm as a light source and the upper section of a magnetic recording medium 1 is irradiated with light from the light source, the amount of transmitted light from the magnetic recording medium 1 changes while depending upon the film thickness of the magnetic recording medium 1. Since light has proper transmittance to the magnetic recording medium 1 at that time, the amount of transmitted light required for detecting the unevenness of film thickness can be ensured sufficiently. Since the light-emitting diode 5 does not dissipate excess heat energy, it does not give thermal harm, and the emission unit is reduced, thus inhibiting the variation of the amount of light of the light source. Accordingly, detection having high sensitivity is enabled.

Title: Control method for grinder grinding robot
Inventor: OKI NOBUAKI
IPC: B24B49/16
Filed: 1990-10-26
Abstract: PURPOSE:To make a finishing face a pretty one, by accelerating and decelerating the feeding of a grinder in multi-stage, according to the load current of the grinder. CONSTITUTION:At least more than one current levels lower than the rated current and higher than a control start level with respect to a grinder 2 are set, the feeding of the grinder 2 is accelerated in the case of the load current whose current level is detected by a sensor 8 being below, and it is decelerated in case of being above vice versa. Thus the feeding of the grinder 2 is accelerated in case of the load current of the grinder 2 being found below the current level, and decelerated in case of being found above vice versa, so the load current is always maintained at the rated current vicinity. Consequently, grinding can be performed at a high speed with the capacity of the grinder 2 being utilized enough, and also the range of the disposable burr quantity is widened.

Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a luminaire for tunnels having a cover glass which can keep cleaning property against pollution with such as soot and smoke by forming a surface layer with a specified composition on the surface of the cover glass of the luminaire for tunnels. SOLUTION: A surface layer 20 containing photocatalytic particles, silicone, a water-repelling fluoro-resin is formed on the surface of a substrate of a cover glass 18 of a luminaire 10 for tunnels. When light rays which can photoelectrically excite a photocatalyst are irradiated, organic groups forming bonds with silicon atoms in the silicone molecule are at least partially substituted with hydroxyl group due to the photocatalytic function in at least a part of the silicone exposed to the outside atmosphere. Consequently, the resultant silicone is provided with a structure in which parts having hydrophilic property in the silicone exposed to the outside atmosphere and parts having water repelling property in the water-repelling fluoro-resin exposed to the outside atmosphere are microscopically dispersed.  As a result, not only hydrophilic substances but also the hydrophobic substances are not stuck to the surface, leaving the surface in clean state.
