Title: Manufacture of semiconductor device
Inventor: KUDO NOBORU
IPC: H01L23/52
Filed: 1987-03-26
Abstract: PURPOSE:To enable the second piling (reworking) of Al when the formation of an upper layer Al wiring is defective, by connecting the upper layer wiring with a lower layer wiring via a film which is not etched by an Al etching solution. CONSTITUTION:A first layer Al 3 is piled on an oxide film 2 and next a resist 4 is used as a mask so as to etch the first layer Al 3. In succession, after an interlayer insulating film 5 is piled on the first layered Al 3 and the oxide film 2, a resist is used as a mask to etch the interlayer insulating film 5 and form a contact hole and then the resist is removed. Next, a film 6 of e.g., W, which is not etched by an Al etching solution, is formed by a chemical vapor growth method. W is not formed not on the SiO2 5 but on only the Al 3 inside the contact hole. Even if the upper layer Al is etched by a solution which contains phosphoric acid, for example, the lower layer Al is hence protected by the W 6 and not hence etched, so that the reworking of the upper layer Al is enabled.

Abstract: PURPOSE:To prevent the deterioration of superconductive characteristics by forming a Tl group oxide superconductive thin-film onto a substrate, shaping a hole not reached to the substrate to the thin-film through sputtering etching by convergent ion beams and manufacturing a micro-bridge. CONSTITUTION:An oxide superconductive thin-film 2 is formed onto a substrate 1, an anode in the anode and a cathode as counter electrodes is grounded while the substrate 1, on which the superconductive thin-film is deposited, is placed onto the anode, the cathode is composed of a target material consisting of a superconductive sintered body, and high negative voltage is applied. MgO(100) is used as the substrate 1, and the target material is made up of Tl3Ba2Ca2Cu3 Ox so that the thin-film formed onto the substrate 1 is changed into the oxide superconductive thin-film of Tl2Ba2Ca2Cu3Ox without executing annealing treatment. A hole 3 is shaped to the thin-film 2 through sputtering etching by convergent ion beams, and micro-bridges 4, 4 are manufactured. Accordingly, the superconductivity of the oxide superconductive thin-film is not damaged.

Title: Manufacture of heat sink
Inventor: ISOYAMA KIKUO
IPC: H01L23/36
Filed: 1984-04-11
Abstract: PURPOSE:To enable the flat punching of a heat sink to be realized by a method wherein a groove is formed in the periphery in the upper surface of a flat type heat sink, and the projection produced at the time of this groove formation is then flatly punched with a flat die having a vent. CONSTITUTION:Using a copper piece as the heat sink 3, the groove 8 is formed in the periphery in the upper surface of the heat sink 3 by press. In this process, the end of the groove 8 is transformed into the projection 9. This projection 9 must be removed because of being the obstacle against power-transistor fixing and is therefore removed by flat punching. In this case, a press die 10 for flat punching is provided with a vent 12. This manner enables facile flat-punching in the presence of an escape from the vent 12 to outside even when oil 11 interposes in the space formed by the die 10 and the projection 9, resulting in the flattening of the projection 9 to approx. 5mum.

Abstract: PURPOSE:To provide a rivet type clad electric contact in which silver in a silver-oxide compound contact material and another silver forming a basic material are mutually diffused on the whole surface of a joint portion between the contact material and the basic material to prevent the joint portion from being swelled so as to heighten the conjoining strength of the two materials, and also which can stably break and make a circuit without causing the contact material to be peeled off the basic material by arc heat or Joule heat when the contact is incorporated in a relay, a switch or the like and load is applied. CONSTITUTION:Cold pressure welding is given to both of a contact material made of a silver-unoxide and a basic material made of silver so as to form a rivet type contact. Then the contact is heat-treated in an atmosphere of nitrogen gas kept at a temperature of not less than 350 deg.C, and thereafter the contact is oxidized to change the silver-unoxide forming the contact material into its corresponding silver-oxide one.

Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To greatly reduce a formation time for a stamp and eliminate the danger of damaging the stamp, by setting either a light transmission cell or a light-shutting cell, and letting light beams from a projection part pass only through the light transmission cell and illuminate the stamp. SOLUTION: Either a light transmission cell 350 or a light-shutting cell 351 is set for each cell of a liquid crystal shutter 300, and an original picture is formed. The light is started to be projected from a projecting part 301. The light from the projecting part 301 passes only through the light transmission cell 350 to reach a stamp 100 and illuminate the stamp. At the stamp 100 illuminated by the light, a black part is where the light passes the light transmission cell 350 to reach the stamp 100 and illuminate the stamp 100, and a white part is where the light is shut by the light-shutting cell 351 and therefore the stamp is not illuminated. The stamp 100 is shadowed in this manner.
