Title: Measuring method of deterioration degree of ferrite heat-resisting steel
Inventor: KOMATSU SHIYUUICHI
IPC: G01N3/32
Filed: 1979-08-20
Abstract: PURPOSE: To easily and surely measure the deterioration of time aging for heat- resisting steel, by measuring the size of subgrain near the initial austenite bondary of ferrite heat-resisting steel used at high temperature, and comparing it with the criterion.  
     CONSTITUTION: The ferrite heat-resisting steel used at high temperatures such as steam turbine members forms the subgrain with the rearrangement of transformation introduced at heat treatment near ex-austenite. The subgrain size is measured, and the degree of deterioration formed from the fatigue deterioration test is compared with the deterioration criterion chart showing the relation between the subgrain size and the deterioration to estimate the deterioration of heat-resisting steel. For example, if the subgrain size is 2.5μ at point A, and the ratio of the creep deterioration of steel to fatigue deterioration is analyzed as 6:4 from the operation pattern, the life expectancy can be estimated from the figure as about 40%. This value is well in agreement with the simulated deterioration test.

Inventor: KOMATSU YUJI
IPC: H01L21/285
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device and a fabrication method thereof in which the gate electrode can be made thick enough to block implantation of ions into a channel when a self-aligned diffusion layer is formed by ion implantation even if a material having a work function close to the midgap of silicon is employed in the gate electrode and an undue tensile stress is not applied to a gate oxide. SOLUTION: A gate electrode 11 is composed of WSix 13 and polysilicon 14 and the lower layer of WSix touches a gate oxide 12. Since the work function of WSix is close to the midgap of silicon, threshold voltage Vth can be controlled to a correct level. Tensile stress being applied to the gate oxide can be lessened by making thin the WSix layer and the entire gate electrode can be made thick enough by depositing polysilicon on the WSix .
