Patent JP-2002118117-A (JP)
Title: Manufacturing method of insulating gate type semiconductor device
Inventor: ISHIDA HIROYASU
IPC: H01L21/336
Filed: 2000-10-10
Abstract: PROBLEM TO BE SOLVED: To overcome the problem of a prior art such that the formation of a source region requires a mask in a conventional power MOSFET, failure due to the mismatch in the mask occurs when making fine the power MOSFET, and the reduction of costs is difficult, and that trench width expands since a trench opening is formed by high-temperature dummy oxidation although the trench opening is rounded to avoid the concentration of an electric field. SOLUTION: After the trench is formed, a high-concentration impurity is introduced into a polysilicon layer for covering an entire surface before etchback, thus allowing polysilicon to remain in a sidewall shape only at the trench opening, diffusing impurities, and hence forming the source region by self-alignment. As a result, costs are reduced, thus contributing to reducing costs. Also, dummy oxidation can be made at a low temperature, thus inhibiting the spread of the finishing width of a trench.

Title: Game ball inducing member and method of inducing game ball
Inventor: KUBO KAZUNORI
IPC: A63F7/02
Filed: 2000-10-16
Abstract: PROBLEM TO BE SOLVED: To improve the fact that wide space is required for placing game ball inducing members and efficiency of producing the game ball inducing members is not good.

Title: Printed board and method of discriminating stress history thereof
Inventor: KAJIWARA EIJI
IPC: H05K3/34
Filed: 2000-10-23
Abstract: PROBLEM TO BE SOLVED: To reliably discriminate whether a specified stress or more has been exerted on a board in the past. SOLUTION: A specified stress or more exerted on a board 2 causes a part of a conductive line 3 to be broken or deformed. A measuring instrument is connected to a measuring terminal 4 to measure the resistance of the conductive line with a current flowing on this line, thereby recognizing that the specified stress or more has been exerted on the board 2 in the past. In this case the once broken or deformed conductive line 3 never recovers its original state and, even if, e.g. no stress is exerted on the board 2 at present, the history that the specified stress or more has been exerted on the board 2 is never deleted.
