Title: Manufacture of superconducting film
Inventor: TANAKA ATSUSHI
IPC: H01L39/24
Filed: 1988-11-30
Abstract: PURPOSE:To enable the manufacture of a superconducting film having a high critical temperature and current density on an alumina substrate by forming the reaction layer of the substrate and an oxide film at the interface of a ceramic substrate and the oxide film via heating treatment. CONSTITUTION:The reaction layer of a ceramic substrate and an oxide film is formed at the interface of the substrate and the film via beating treatment. For example, when a thin film of YBa2Cu3O7-d (d>0.5) is formed, an alumina substrate 1 with a 4mum thick oxide film 2 formed thereon using an oxide of Y:Ba:Cu=1 as a target is subjected to heating treatment in the atmosphere of oxygen. The film 2 reacts with the substrate 1 near the interface thereof and BaAl2 and Y2BaCuO5 are produced, thereby forming a reaction layer 3 containing the aforesaid materials. The substrate 1 is further heated and baked in the atmosphere of oxygen. Ac cording to the aforesaid construction, the unreacted layer 2 begins to react and a superconducting film 4 composed of YBa2Cu3O7-d is formed. In this case, the aluminum of the substrate 1 and the superconducting film 4 are prevented from reaction with each other due to the existence of the reaction layer 3.

Title: Manufacture of charge transfer device
Inventor: YAMAKAWA SATOSHI
IPC: H01L29/762
Filed: 1989-11-22
Abstract: PURPOSE:To decrease the resistance of an electrode by providing a double- layered structure of a polysilicon film and a silicide film for the first and second electrodes of a charge transfer device. CONSTITUTION:A polysilicon film 4 and a silicide film 11 are sequentially deposited on a silicon dioxide film 5a on the surface of a P-type silicon substrate 1 on which an N<-> impurity layer 2 is formed. Then a resist pattern 8 formed on the silicide film 11 is used as a mask, and multilayered films of silicide patterns 11a and 4a are formed by machining. Thereafter, a polysilicon film 23a is deposited on the entire surface. With the resist as a mask, the polysilicone film 23a is machined so as to cover the silicide patterns 11a and 4a. Thereafter, a polysilicon film 6 as a second layer and a silicide film 24 are sequentially deposited on a silicon dioxide film 5 which is formed on the entire surface. Then, a resist pattern 9 is formed on the silicide film 24, and multilayered films of polysilicone patterns 6a and 24a are formed by machining. Then, with the polysilicon patterns 6a and 24a as mask, an interlayer insulating film 7 is formed on the entire surface. Thus, the resistance of a gate electrode is decreased, and the potential difference between the gate electrodes can be eliminated.

Title: Heating apparatus for semiconductor manufacturing apparatus
Inventor: HAMANO MASATSUYA
IPC: H01L21/68
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a heating apparatus for a semiconductor manufacturing apparatus, esp., of its substrate housing, or reduce the wt. of a panel heater of the heating apparatus and the time required for pre-heating substrates to improve the throughput. SOLUTION: The apparatus comprises a vacuum chamber 1, housing a panel heater housing frame 10 having vertical stages of panel heaters horizontally laid across the panel heater housing frame, to support and heat substrates 8 between the panel heaters. Both ends 13 of each panel heater are thick, and its middle 12 is thin. Resistance-heating elements 6 are buried in the ends of the heater to heat a semiconductor fabrication apparatus. Since the middle of the panel heater having influence on the substrate housing is made thin, the vertical pitch of the panel heater can be small, and since no resistance- heating element exists at the middle, the panel heater itself can be light in wt. to reduce its bending.

Title: Digital data receiver
Inventor: YUUSUKE OOTA
IPC: H04B10/158
Filed: 1993-11-12
Abstract: PURPOSE: To lower the sensitivity of a data receiver to dc dark level light and to improve the input data signal detection sensitivity and precision by removing a direct current or low-frequency current generated by a photodiode at a data receiver input terminal. CONSTITUTION: Peak detecting circuits A2 P and A2 N convert positive and negative outputs Vo <+> and Vo <-> of an input amplifier A1 into a direct-current(dc) difference signal Icomp through a comparing amplifier A4 . This signal is subtracted from an input signal Iin and a dc feedback loop is established in a dark level compensator circuit 600. This loop cancels an input dark current as well as all dc offset signals to eliminate the difference output of the dc signal of an amplifier A1 to zero. Once the circuit A2 P sets IinZr/2 as a threshold value, the difference output of the amplifier A1 vibrates vertically symmetrically about the logical threshold value. Therefore, the positive and negative peak vibrations and the outputs of the circuits A2 P and A2 N become uniform.  Those become difference voltages to the amplifier A4 , and consequently the signal Icomp of the output of the amplifier A4 does not vary.

Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To improve the light projecting efficiency, and while to lower the driving voltage, and to simplify the structure by forming two pairs of electrodes to be used for maintaining electrode in separate layers, and providing a dielectric layer between them, and while providing a MgO film at a pact, which contacts with a discharge gap of a front surface board. SOLUTION: Two pairs of maintaining electrodes, an X-electrode 7 and a Y-electrode 8 to be arranged in a front surface board 1 are formed in separate layers of the front surface board 1, and a dielectric layer 11 is formed between them. With this structure, two pairs of the electrodes can be arranged sufficient close to each other, and finally, they can be overlapped with each other. Discharge is started in the condition that the discharge starting voltage is always at the minimum, and since discharge is spread to the whole area of the electrode width, discharge in a wide range can be generated at a remarkably low starting voltage. Discharge starting voltage is lowered and lifetime of a panel can be prolonged by forming the Y electrode 8 of a transparent electrode and providing a MgO film 12 at a part, which contacts with a discharge gap of the front surface board l.

Title: Electromagnet driving equipment
Inventor: UCHIDA KAZUMI
IPC: H01F7/18
Filed: 1986-12-23
Abstract: PURPOSE:To prevent the external radiation of a switching noise by making a metal frame absorb the noise by electrically connecting the metal frame to the circuit of a coil for operating an electromagnet rather than to a switch for making. CONSTITUTION:A metal frame 24 which is made of an aluminum die casting and contains a coil 5 for operating an electromagnet, an iron core, etc., and a terminal A1 are electrically connected by a connecting wire 50. By connecting the metal frame 24 to the terminal A1 in this way, a switching noise generated from the coil 5 for operating the electromagnet by the switching operation of a switching transistor 6 and radiated in the air is absorbed by the metal frame 24 and is returned to a condenser 3 for absorbing noise through the metal frame 24, the connecting wire 50 and the terminal A1. This prevents the propagation of the switching noise in the air from the coil 5 for operating the electromagnet.
