Patent JP-H03224273-A (JP)
Title: Manufacture of semiconductor device
Inventor: INOUE FUMIHIKO
IPC: H01L29/788
Filed: 1990-01-30
Abstract: PURPOSE:To form a tunnel oxide film over a prescribed area under a condition where the formation of the film is well controlled and the thickness of the film is easily controlled by adding a heat treatment process after ion implantation is made to a substrate so as to reduce the etching rate of a gate oxide film. CONSTITUTION:After a gate oxide film 3 is formed on the element forming area of a p-Si substrate 1, ions of a conductivity type opposite to that of the substrate 1 are implanted into the film 3 by using a resist 11 with an opening in corresponding with a drain area 10 as a mask and a high-concentration layer is formed. After the high-concentration layer is formed, the resist 11 is removed. When the substrate 1 is heat-treated in an inactive atmosphere under such condition, the etching rate of the high-concentration film 3 is reduced. Therefore, when etching treatment is performed by using the second resist 12 as a mask, the etching to the opening of the mask in the lateral direction is prevented and a tunnel oxide film 3T is formed over a prescribed area with high controllability. In addition, the thickness of the film 3T can easily be controlled.

Title: Leak detecting method for double heat conduction tube vapor generator
Inventor: WATABE ICHIRO
IPC: G01M3/26
Filed: 1986-01-31
Abstract: PURPOSE:To detect damages to both internal and external tubes of a heat conduction tube with simple constitution by charging helium having pressure higher than the pressure in the internal tube between the internal and external tubes, and detecting variation in the pressure of the helium. CONSTITUTION:Helium He of about 160kg/cm<2> higher than the pressure in the internal tube 8 is charged in spaces 9 and 10 and the gap between the internal and external tubes which communicate with both spaces. A pressure gage 17 is linked with either of the spaces and analyzers 15 and 16 are linked with a vapor outlet passage 13 and an outlet flow passage 14 for liquid sodium respectively. For example, if the internal tube 8 cracks, the He leaks to the vapor side because the pressure of the He is higher than the vapor pressure and the leak is detected by the pressure gage 17 from a drop in He pressure. Further, the He concentration in vapor increases, so that damage to the internal tube 8 is found by the analyzer 15. If the external tube 7 cracks, on the other hand, the He leaks to the liquid sodium and the pressure drops. The leak is also detected in this case as well and the damage to the external tube 7 is known through the analyzer 16.

Title: Hall element using gallium arsenide crystal
Inventor: HOUJIYOU AKIMICHI
IPC: H01L43/06
Filed: 1978-02-24
Abstract: PURPOSE:To obtain the Hall output voltage which is as high as that obtained through the high-quality substrate by growing the GaAs active layer featuring the product of carrier density n/cm<3> and thickness mum of more than 5 X 10<16> on the low-quality semi-insulating GaAs substrate featuring the displacement density of more than 2 X 10<4>/cm and the specific resistance of more than 1 X 10<4>OMEGAcm. CONSTITUTION:The GaAs active layer composed of layer 2 whose carrier density increases as the temperature increases and layer 3 whose carrier density does not change with the temperature is grown by the vapor growth or the liquid-phase growth on semi-insulating GaAs substrate 1. In this case, substrate 1 must feature the displacement density of more than 2 X 10<4>/cm<3> and the specific resistance of more than 1 X 10<4>OMEGAcm, which means the low quality. At the same time, the active layer is prescribed to feature the product of more than 5 X 10<16> between carrier density n/cm<3> and thickness mum. As a result, the temperature dependence to the normalized output voltage shows more than 95% of the room temperature at 200 deg.C and more than 90% even at 250 deg.C respectively, thus lowering the production cost.
