Title: Evaluation method for semiconductor device
Inventor: SHIMOYAMA NOBUHIRO
IPC: H01L21/66
Filed: 1995-04-13
Abstract: PURPOSE: To grasp the damage on a produced semiconductor device due to plasma more accurately by comparing the transconductance life indicative of a specified variation in the transconductance of MOSFET and the substrate current dependency of the varied state. CONSTITUTION: A voltage is applied to a gate electrode 3 and the drain in a heavily doped source-drain region 6 and the threshold voltage variation life and the substrate current dependency of gm variation life are compared. In other words, a voltage is applied to the gate electrode 3 and the drain terminal 6 of an MOSFET and the threshold life at the time and the substrate current dependency of the state of variation thereof are compared with a transconductance lifetime and the substrate current dependency of the state of variation thereof. With such a method, damaged on the MOSFET due to plasma can be grasped.

Title: Gear structure
Inventor: IIJIMA AKIRA
IPC: F16H55/18
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of tooth hammering noise by a method wherein a backlash between a subgear and a mating gear is reduced to a value smaller than a backlashbetween a main gear and a mating gear and a fit-in gap between the subgear and a shaft is set to a value larger than the backlash between the subgear and the mating gear. SOLUTION: A backlash of a main gear 3 is set to a value higher than a backlash of a subgear 7. A force of press of the subgear 7 against a main gear 3 through the force of a disc spring 12 is set to a value at which, when the tooth 7d of the main gear 7 is collided with the tooth 9d of a mating gear 9, the main gear 3 is prevented from sliding-over the side of the subgear 7 and collision with the tooth 9d of the mating gear 9. A fitting gap X between the inside diameter part 7a of the subgear 7 and the outer peripheral surface 3e of the inner peripheral cylinder part 3a of the main gear is set to a value higher than a backlash between the subgear 7 and the mating gear 9. This constitution prevents the generation of hammering noise and reduces the generation of noise.

Title: Formation of single crystal silicon film on insulating film
Inventor: NAMURA TAKASHI
IPC: H01L21/84
Filed: 1988-04-11
Abstract: PURPOSE:To reduce manufacturing cost and to solve problems of crystallinity, by a method wherein on a multilayer film produced by forming a silicon oxide film and a silicon nitride film in turn on a silicon substrate, a first to a third single crystal silicon films are formed, in this order. CONSTITUTION:As with a pattern width of a multilayer film consisting of a first silicon oxide film 2, a first silicon nitride film 3 and a second silicon oxide film 4, a short size is selected therefor so as to be suitable for crystal growth regardless of the element size, a single crystal silicon film 5 is produced which contains small amounts of crystal defects. In separating a second single crystal silicon film 9 from a silicon substrate 1, a fourth silicon oxide film 8 has already been formed on the first single crystal silicon film 5 in the preceding process, so that when the second single crystal silicon film 9 is formed, a step configuration is generated on the surface of the single crystal silicon film 5 in a self-alignment manner. Since such a configuration is effectively utilized, only one time of pattern formation of the multilayer film is needed over all the processes in addition to high processing accuracy. As a result, a single crystal silicon film can be formed which contains small amounts of crystal defects, and manufacturing cost can be also reduced.

Title: Positive temperature coefficient thermistor
Inventor: MINATO TAKESHI
IPC: H01C7/02
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To improve reliability by soldering a lead to a positive temperature coefficient thermistor element and coating it with a phenol resin. SOLUTION: An uncoated product in which a lead 4 of a CP wire is soldered by a solder 5 to a positive temperature coefficient thermistor element 1 having a tin plated electrode for nickel plating and soldering provided on both sides thereof is impregnated with a phenolic resin 6, and plating is carried out, for example, for 30 minutes at 150 deg.C. Then, with this product coated with the phenolic resin, the flash pressure resistance and on-off cycle are measured. (The flash pressure resistance is measured by instantaneously applying a voltage to the element and measuring the voltage until the element breaks down, and the on-off cycle is measured by repeating a cycle consisting of application of an AC of 140 V to the element for one minute at the room temperature and cooling of the element for five minutes, and checking the solder fragility state).  As a result, the flash pressure resistance is higher than that of a product with a silicone resin, and with respect to the on-off cycle, too, the life can be made longer than that of a silicone resin.
