Patent JP-H07235668-A (JP)
Title: Mos type transistor
Inventor: SAITO TATSU
IPC: H01L29/08
Filed: 1994-02-23
Abstract: PURPOSE:To improve breakdown strength at the time of avalanche without increasing ON resistance by diffusing impurities having the reverse conductivity forming action into the central part of a channel diffusing region at the central part of a unit cell structure, and enhancing the electric field of the central part of a p-n junction. CONSTITUTION:An n<+> well layer 8 is formed by the diffusion of donor impurities from the surface of an n<+> silicon substrate l. Then, polycrystalline silicon is deposited on the surface through an oxide film. The silicon is patterned so that the n<+> well 8 comes to the intermediate part of a gate electrode 6 comprising the polycrystalline silicon. When a p-type channel region 2 is formed by the diffusion of acceptor impurities with the gate electrode 6 as a mask, the p-n junction is curved to the surface side at the part of the n<+> well 8, wherein the donor impurities are diffused. Therefore,the voltage drop directly beneath a source region by the inflow of the avalanche current from the peripheral part of the channel diffused region is prevented by making the avalanche current flow into the wide area part at the center. Thus, the avalanche breakdown strength can be improved without increasing the ON resistance.

Title: Press forming device
Inventor: TAKATANI MASARU
IPC: B21D22/20
Filed: 1983-02-18
Abstract: PURPOSE:To perform press forming which generates no plane distortion at all by heating locally at least one point in a partial forming section or plane distortion generating section to the temp. higher by a specific temp. or above than the periphery thereof. CONSTITUTION:The plane distortion generated in a press-forming article in which a plane occupies a greater part and which is formed partially is possibly the light buckling owing to a residual compressive stress. Therefore if said part is shrunk, the residual compressive stress can be relieved and the plane distortion can be eliminated. More specifically at least one point in the partially forming section or the plane distortion generating section is locally heated during forming and is formed by providing a temp. difference from the non-heated part, by which the locally heated part is deformed while said part is kept thermally expanded during forming. When the temp. is made uniform upon ending of the forming, the thermally expanded section is shrunk and the residual compressive stress which is ought to be generated by elastic recovery after the forming is removed. The above-described temp. difference is essentially regulated to >=20 deg.C.

Title: Manufacture of compound semiconductor element and manufacturing device therefor
Inventor: SHIMAZU MITSURU
IPC: H01L21/338
Filed: 1985-02-15
Abstract: PURPOSE:To produce a compound semiconductor element preventing the short channel effect from occurring by a method wherein a semiinsulating compound semiconductor substrate implanted with ions is annealed at 400-500 deg.C in an N2 and/or H2 atmosphere to be activated. CONSTITUTION:A semiinsulating GaAs substrate 1 is implanted with Si ion utilizing an SiO2 mask 17 to make a channel 2. Firstly a gate electrode 6 is selectively formed implanting the channel 2 with ion utilizing the electrode 6 as a mask to form N<+> layers 3. At this time, vacancies of interstitial atoms are produced in the N<+> layers 3 at high concentration. The surface is covered with a CVD SiO2 film 16 to prevent the constituent elements from evaporating out of the substrate 1 during activation process at 800-900 deg.C. Secondly, the N<+> layers 3 are annealed in N2 and/or H2 at 400-500 deg.C for 20-30min to extinguish the vacancies. Finally the N<+> layers 3 are processed at 800-900 deg.C for 20-30min leading any implanted impurity atoms to lattice points to active them electrically. Through these procedures, any short channel effect may be prevented from occurring due to no channel current at OFF state of FET since no impurity atoms are diffused below a gate due to extinguished vacancies by means of preliminary annealing process.

Title: Fixing device
Inventor: OTSUKA YASUMASA
IPC: G03G15/20
Filed: 1993-02-16
Abstract: PURPOSE:To prevent the occurrence of a defective fixing and a high temperature offset even if working and stopping are repeated through the use of the heater of high capacity of heating-up and cooling-down by setting a fixing temperature based on the temperature of the heating member before the control of the fixing temperature is started and a change in the temperature at the time of completing the supply of prescribed power to the heating member. CONSTITUTION:When an image forming signal is inputted, the energization of a heat generating zone is started and the energization of a heating element 6 is controlled so as to maintain a prescribed fixing control temperature with the detection temperature of a temperature detecting element. In other words, the detection temperature T1 of the temperature detecting element 4 just before an action has been started, is classified into three levels. When the detection temperature T1 is <50 deg.C, it is judged that a device is in cooled state and the higher fixing temperature of 190 deg.C is selected and when the temperature T1 is >=50 deg.C and <=70 deg.C, 180 deg.C is selected and when the temperature T1 is >=70 deg.C, it is judged that the device is in warmed up state and 170 deg.C is selected. A c ontrol temperature Tc is set in this manner, so that both of the defective fixing and a hot offset can be prevented.
