Title: Manufacture of semiconductor device
Inventor: HIGUCHI TOSHIHIKO
IPC: H01L21/3205
Filed: 1988-07-08
Abstract: PURPOSE:To form a wiring layer having no step by oxidizing a metal film formed on a board with the part formed with wirings as a mask, and forming a conductive metal region and a metal oxide insulating region. CONSTITUTION:A metal film made, for example, of titanium 102 is formed on an insulating film 101 of a semiconductor device by sputtering technique. It is then coated with photoresist 103, and the photoresist except a position to be formed with wirings is removed by photolithography technique. Thereafter, a semiconductor substrate is introduced into oxygen plasma 104. The titanium metal is easily oxidized in the oxygen plasma. Since the titanium oxide 105 is not conductive different from that at the time of titanium metal, the position not covered with the photoresist after this step becomes an insulator for isolating the wirings. The photoresist after oxidation with the oxygen plasma is dissolved to be removed with a organic solvent thereby to form wirings of the titanium metal and an insulating region of titanium oxide on the insulating film.

Title: Probe and probe card using this probe
Inventor: OKUBO MASAO
IPC: G01R1/067
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To improve measuring accuracy of electric characteristics of a measuring object LSI chip by a probe card without requiring to improve manufacturing accuracy of a probe by forming the contact part of the probe and the connecting part so as not to exist on the same perpendicular, and arranging the deforming part deformed when vertical force is applied to the connecting part. SOLUTION: The tip of a probe 100 is the contact part 111 of an LSI chip to an electrode pad, the deforming part 122 is arranged to be deformed when vertical force is applied to the connecting part 121 on the rear end, and the contact part 111 and the connecting part 121 do not exist on the same perpendicular. Thus, since a dimensional tolerance of the probe 100 is absorbed by the deforming part 122, contact resistance can be kept constant. In a large number of probes 100 used for a probe card, height positional accuracy of the connecting part 121 can be roughened more than usual. Actually, even in coping with a chip having an electrode pad of a narrow pitch, a height position of the connecting part can be roughened, so that measuring accuracy of various electric characteristics of the same degree can be secured without further enhancing manufacturing accuracy of the probe 100.

Title: Manufacture of oxide superconductive wire rod material and device therefor
Inventor: TOMOMATSU KAZUHIKO
IPC: H01B12/04
Filed: 1989-06-30
Abstract: PURPOSE:To stably obtain a long oxide superconductive wire rod with high composition accuracy by indirectly heating a raw wire rod through a pipe arrangedly installed at a laser beam condensing portion to form a melting potion inside the pipe. CONSTITUTION:A raw wire rod 11 of an oxide superconductive composition is made to be inserted into the inside of a pipe 16, and a laser beam 1a is made to be condensed in the pipe 16 to locally melt the raw wire rod 11 so that a molten solution is polled up from the upper end of a melting portion of the raw wire rod 11 formed inside the pipe 16 to be coagulated. As a pipe will exists, therefore, between the melting portion and each mirror 15, the evaporated material of component elements produced from the melting portion as a result of heating is never splashed toward the respective mirrors 15 so that pollution of the surfaces of the mirrors 15 can be reduced. As the spaces excluding the upward and downward directions are closed by the 16, the evaporation of composition components at the melting portion can be reduced and a change in the composition of the molten solution is a little. Thereby, it is possible to stably get a long oxide superconductive wire rod with a prescribed composition.

Title: Semiconductor device
Inventor: KIMURA NAOKI
IPC: H01L23/36
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To reduce a warp owing to the rise of a temperature and to improve electric capacity by arranging substrates on both faces of a semiconductor element. SOLUTION: The metal coating parts of the composite substrates 11 and 15, in which at least each face on ceramic plates is coated with metal, are joined to both faces of the semiconductor element 13 through semiconductor layers 12 and 14. When the temperature rises, two thermal stresses operate on both faces of the semiconductor element 13 so that the direction of the warps becomes opposite, and the thermal stresses are balanced so as to reduce the warp. In the semiconductor device which is mounted on a cooling member and is used, the thickness of a composite member positioned on the opposite side of the cooling member is set to be not less than 1.5 times the thickness of the composite substrate jointed to the cooling member. Thus, the warp owing to thermal stress can be reduced much more. Consequently, the materials of the composite substrates 11 and 15 are not necessary to be regulated, the calorific value of the semiconductor element 13 can be increased and electric capacity can be improved.

Filed: 1990-06-28
Abstract: PURPOSE:To prevent crack and enhance the power generating efficiency by making an air electrode in the form of a cylinder of porous structure in which reinforcement is embedded, and putting a solid electrolyte and fuel electrode one over another on the outside surface of this cylindrical air electrode. CONSTITUTION:A layer of solid electrolyte 21 and a fuel electrode 22 are put one over another on the outside surface of an air electrode 20 formed cylindrically. The cylindrical air elecrode 20 on the central side works also as a supporting tube and is of porous structure in which reinforcement 23 is embedded. Thereby the air electrode 20 as supporting tube is prevented from cracking, which might lead to damage of the whole fuel cell, due to temp. change during or before/ after power generation or due to heating to be made when the layer 21 of solid electrolyte or fuel electrode 22 is formed on the periphery. Further because the air electrode 20 can be embodied with large wall thickness, the electroconductivity is increased to result in enhancement of the power generating efficiencuy.

Title: Voltage controlled oscillating circuit
Inventor: YAMAKIDO KAZUO
IPC: H03K7/06
Filed: 1982-10-01
Abstract: PURPOSE:To reduce a well current being a cause to the production of latchup by splitting a charging capacitor into two and grounding each end. CONSTITUTION:When an FF12 is set, transistors (TR) 6, 7 are turned on, a current I4 flows as shown in solid lines to charge a capacitor 91 being one of two-split capacitors. Thus, a voltage at a point VA increases linearly, but the potential at a point VB is kept to a ground potential. When the potential of the point VA reaches a prescribed value VTH, a voltage comparator 11 outputs a high level signal and the FF12 is reset. Thus, the TRs 6, 7 turn off, TRs 5, 8 turn on, a voltage of the capacitor 91 is discharged at the TR8, the flowing of the current I4 is changed into dotted lines, the charging of other capacitor 92 being one of the two-split capacitors is started, and when a voltage at a point VB reaches the VTH the same as above, the FF12 is set and the state is restored to the initial state.
