Title: Package for containing semiconductor element
Inventor: OGAWA NAOTO
IPC: H01L23/34
Filed: 1987-03-18
Abstract: PURPOSE:To prevent the occurrence of cracks and breakings due to thermal expansion difference, and to operate a semiconductor element normally and stably for a prolonged term by applying and forming a radiator consisting of a composite metallic body onto the outer surface of a ceramic vessel housing the element. CONSTITUTION:A metallic layer 8 is mounted onto the base of a ceramic base body 1, and a metallic radiator 9 is set up to the metallic layer 8 through a solder material. The radiator 9 is shaped by a composite metallic body in which copper plates 9b are joined with a plate 9a composed of an invar alloy, and absorbs and dissipates the heat of a semiconductor element 4. The alloy plate 9a inhibits the thermal expansion of the copper plates 9b by the difference of the thermal expansion coefficients of the alloy plate 9a and the copper plates 9b, and the thermal expansion coefficient as a whole is brought close to the thermal expansion coefficient of ceramics. Consequently, the generation of cracks and breakings due to stress resulting from thermal expansion difference is prevented in the base body 1 made of ceramics. Accordingly, the element can normally be operated stably for a prolonged term.

Filed: 1986-03-20
Abstract: PURPOSE:To form a groove efficiently on the circumferential surface with less burrs generated by cutting gear shaped member with plural pairs of cutting tools which are rotated relatively to the opposite direction while being fed by one pitch of its tooth profile. CONSTITUTION:A timing pulley 1 is rotated while being divided at a pitch P equivalent to its one tooth profile 1a, 1a... No.1 and No.2 cutting tools 7 and 7, and 8 and 8 are provided in the pulley 1 while they can be advanced/ retreated whereby the tool 7 is reversely rotated against the tool 8.

Title: Manufacture of semiconductor device
Inventor: KASAHARA OSAMU
IPC: H01L23/52
Filed: 1982-04-19
Abstract: PURPOSE:To obtain a bonding pad with large adhesive strength by providing a first wiring layer on a first dielectric film on the Si substrate, covering this layer with a second dielectric film, and introducing the pad, which is connected over the second dielectric film with the first wiring layer, in the portion where no wiring layer exists. CONSTITUTION:A diffusion layer is formed through the window of SiO24 to a Si substrate 1. In this window Mo7, Al9 are stacked up and are simultaneously patterned to form a first wiring layer, which is covered by a CVDSiO210. Openings 11, 10a are provided to the SiO210 and Al12 is evaporated on the surface. Using the photo etching a second layer wiring pattern 12a and a bonding pad 12b are made simultaneously. This constitution enables direct connection to Al to be used in most of the pad-SiO2 connection, eliminating the danger of separation. The use of the thermal oxidation film can make wire bonding perfect. Since the first wiring layer 7, 9 is covered by the dielectric film 10, the etching for opening the window 10a does not affect the film 4 thereunder, thus preventing the second layer wiring from being broken at that portion.

Title: Measuring method for radioactivity of tritium
Inventor: SAITOU TOMOO
IPC: B01D59/28
Filed: 1981-04-30
Abstract: PURPOSE: To detect a very small amount of  3 H safely with high precision by adding gazeous H 2 , H 2 O and low-rank hydrocarbon to a sample gas containing tritium  3 H, passing a mixture thus obtained through an isotope exchange reaction catalyst layer, and measuring the radioactivity in the H 2  and hydrocarbon containing  3 H wherefrom H 2 O is excluded.  
     CONSTITUTION: H 2 , H 2 O and low-rank hydrocarbon of C 1 WC 3  are added in gaseous forms to a sample gas containing  3 H. H 2 O may not be added when  3 H-containing water  is measured. A mixture thus obtained is passed through an isotope exchange reaction catalyst layer, such as Pt-Al 2 O 3 ,  3 H is transformed into H 2  containing  3 H and hydrocarbon containing  3 H at the temperature of 200W300°C, and water is excluded by cooling or adsorption in an H 2 O excluding device subsequent to the catalyst layer. A gas thus obtained is sent to a gas counting tube unit and thereby the radioactivity in the gas is measured. In this way, a very small amount of  3 H is detected with far higher  sensitivity than before. In addition, it is unnecessary to heat the device at high  temperature, and therefore, safe measurement can be conducted without generation of a large amount of radioactivity-containing substance. The presence of H 2 O and H 2  promote catalysis and thus the isotope exchange reaction is made rapidly.
