Patent JP-H1154749-A (JP)
Title: Manufacture of semiconductor device
Inventor: MATSUMOTO KOICHI
IPC: H01L29/78
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To suppress the decrease of impurities in an impurity injected layer, by forming the impurity injected layer on the surface of a semiconductor substrate, forming a diffusion prevention layer on the surface of that layer after that, oxidizing the semiconductor subatrate, and forming an oxide film in the interface between the semiconductor substrate and a diffusion prevention layer. SOLUTION: Since thermal oxidation for forming a gate oxide film 8 is performed after a diffusion prevention layer 7 has been formed on the surface of an Si substrate 1, it is possible to prevent B being the P-type impurities of the counter doped layer 6 of the Si substrate 1 at the time of the oxidation from diffusing outwards. Besides, it is also possible to suppress the quantity of B of the counter doped layer 6 to be sucked into the gate oxide film 8 to be formed at the time of this thermal oxidation, since outward diffusion is prevented by the diffusion prevention layer 7. As the result, it becomes possible to suppress the decrease of the quantity of B impurities in the counter doped layer 6. Accordingly, it becomes possible to obtain a buried channel MOSFET which suppresses a short channel effect and has a stable threshold value Vth.

Title: Synchronizer ring
Inventor: KATO SHINJI
IPC: F16H3/12
Filed: 1985-09-21
Abstract: PURPOSE:To produce such a sliding part that has proper frictional force and being excellent in abrasion resistance at that, by forming a plating film, where hard grains are dispersed, in the sliding part situated in an inner circumference of a synchronizer ring. CONSTITUTION:Plating treatment takes place for a sliding part 50 existing in a contact surface of a top land part 40 of a synchronizer ring 10. This plating takes place in the following process that fine grains of metal or ceramic of bout 1-3mum in average grain size are dispersed in a plating solution whereby a plating film of 5-100mum in thickness is produced. Since hardness of a hard grain is higher than that of a ferrophosohorus plating film and excellent in abrasion resistance, the ferrophosohorus plating film is worn out due to slide motion with a gear cone whereby the hard grain comes forth to the surface so that a high friction factor is stably secured. In addition, surface roughness of the plating film is set to below Rz3mum or so whereby the initial friction factor is reduced and, what is more, any hitch at the time of shifting will not occur at all.

Inventor: NORIKI TOSHIKI
IPC: H05B37/02
Filed: 1988-08-24
Abstract: PURPOSE:To make cyclic check easy by installing a photocell, a flip flop and a display circuit and, when a drop of illuminence that is lower than the criterion level is detected, keeping the illuminence stored and displayed. CONSTITUTION:A lighting-up discriminator for street lighting 10 is constituted of a photoelectric cell PC, a flip flop FF and a display circuit 30. When the photoelectric cell PC detects a prescribed level is higher than the lighting-up level of street light, the flip flop FF is reset. When the cell PC detects a prescribed level is lower than the lighting-up level and the light-out level, an output of a converter C1 is reversed and the flip flop FF is reset. Thereby, AND gate 31 of the display circuit 30 is opened and a light emission diode LD comes to be in a flickering condition. As the setting of the flip flop FF is held, it is in a flickering condition even at the time of the day-time round, and stored and displayed so that a trouble of non-lighting-up at night can be detected. Thereby, the night round and the grievance procedure become unnecessary and the maintenance, easy.

Title: Complementary thin film transistor
Inventor: KURIKI MASATO
IPC: H01L21/8238
Filed: 1990-08-08
Abstract: PURPOSE:To simply highly integrate without developing a new device or processing technique by sharing to use active regions of a plurality of thin film transistors, and reducing an area for occupying the transistors. CONSTITUTION:Two n-type and p-type thin film transistors are formed, for example, on an insulating board 12 such as a glass board, etc. Since a gate electrode 3, a gate insulating film 2 and an active region 1 are shared for use of the two transistors, their occupying area is reduced. This is because p-channel and n-channel conductive channels are respectively formed in the vicinity of a boundary between the region 1 and the film 2 by a predetermined voltage level to be applied to the gate electrode. That is, since other type channel is not formed under the condition that either one conductive channel is formed, only p- or n-type transistor is interrupted, and an inverter operation as a complementary thin film transistor is realized.

Title: Production of high hardness and/or friction reduced layer
Inventor: DETOREFU REPENNINGU
IPC: C23C14/32
Filed: 1988-08-26
Abstract: In a process for producing layers with high-hardness and/or low-friction properties, a target material under an electrical potential is transferred in vacuo into a target plasma. The target plasma passes onto a substrate which is under a higher electrical potential than the target material, in order to form the desired layer thereon. The target material is formed from metal, the metal being vaporised by means of an electric arc to form a metal plasma. The transfer of the target material metal into the plasma takes place in the gas phase of ionised carbon.

Abstract: PURPOSE:To contrive increase in the efficiency of ionization as well as to enable the titled device to form a highly efficient thin film having a large area by a method wherein the electrons sent from an ionized filament are effectively used for the ionization of substance using an electric field shielding plate. CONSTITUTION:An electric field shielding plate 19 is provided behind an ionized filament 8. A negative potential is given to the electric field shielding plate 19 by the ionized filament 8, the electrons discharged from the ionized filament 8 are jumped out to the center part of a vacuum vessel and collided with the evaporative substance coming from a crucible. As a result, a potentials distribution is generated around the ionized filament 8 by the infiltration of the electric field formed by an accelerating electrode 13 and a grid electrode 12. Consequently, the electrons (e) discharged from the ionized filament 8 are brought out to the center part of the vacuum vessel, and they are collided with vapor 4. Accordingly, as most of the electrons coming from the ionized filament is used for the ionization of vapor and cluster, the rate of ionization is increased. As a result, the upper limit of ionic current density can be formed in a wide area, and a uniform and highly efficient thin film can be formed in a wide range of area.
