Abstract: PURPOSE:To reduce a reversal direction leakage current of a Schottky junction by a method wherein Al is deposited on a main surface of a gallium arsenite wafer and, after a heat-treatment, the aluminium layer and a reactive product layer are removed by etching and then a junction electrode is formed. CONSTITUTION:A thin N type layer 5 is formed on the main surface of an N<+> GaAs substrate 4 by an epitaxial growth. An SiO2 film 2 is formed on the surface of the thin layer 5 and a part of the SiO2 film where a Schottky junction is to be formed is removed by etching and the N type layer is exposed. After an aluminium layer 6 is formed on the whole surface, a thin GaAlAs layer 7 is formed by a heat-treatment of the GaAs wafer. Because of a diffusion during the heat-treatment, impurities of the surface of the N type layer 5 and heavy metals are captured into the GaAlAs layer 7 and removed with the aluminium layer 6 and the GaAlAs layer 7 by a hydrochloric acid etching. The tantallum layer 8 is deposited and a metal layer 9 is deposited on the tantalum layer 8 and the metal layer 9 and the tantallum layer 8 other than the electrode part are removed by an etching. Then on the backside of the substrate 4, an ohmic electrode 10 made of a gold/germanium alloy is formed. With this constitution, a reversal direction leakage current of the Schottky junction can be reduced and a contact resistance between the electrode metal and the GaAs wafer can be made uniform with low resistance.

Abstract: PROBLEM TO BE SOLVED: To detect a sample gas by, with the use of a sensor of a crystal vibrator which has an adsorption film on its surface, finding a change in resonance frequency of the vibrator due to adsorption of the sample gas by the adsorption film. SOLUTION: When each oscillation circuit 5 and 6 are made into an operating condition, a reference crystal vibrator 1, a crystal vibrator 3 and a crystal vibrator 4 with a cover start vibrating. When a gas is generated, a gas adsorption film 2 on each vibrator 3 starts to adsorb a sample gas molecule, and resonance frequency of each vibrator 3 shifts according to the adsorption amount, and vibration frequency of each circuit 5 shifts. Meanwhile, an adsorption film 2 on the vibrator 4 with a cover does not adsorb the gas, so that the resonance frequency does not change and the adsorption amount changes.  The adsorption amount to each vibrator 3 changes according to temperature, meanwhile the changing amount is constant magnification of an output of the vibrator 4 with cover, so that, by subtracting constant magnification of the output of the vibrator 4 from the output of the vibrator 3, a component corresponding to temperature change of the output of each vibrator is negated.

Title: Data carrier system
Inventor: MASUI SHOICHI
IPC: G06K17/00
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To solve the problem of carrier cancellation in the case of performing anti-collision by allowing each data carrier (slave unit) to store a collision detection state at the time of not receiving a response confirmation signal from an interrogator regardless it returns a response or not. SOLUTION: A slave unit 30 which returns a response decides that carrier cancellation is performed by such a manner that a response confirmation signal does not arrive regardless of its responding and erects a carrier cancellation flag in a RAM 35b. When a flag is set, the unit 30 takes measures to carrier cancellation. That is, the unit 30 decides whether or not the unit 30 performs transmission according to whether one bit is zero or one by using a 1-bit random number generation circuit that exists in the unit 30 itself. Thus, it is possible to avoid carrier cancellation by such a manner that a slave unit 30 in which carrier cancellation occurs stops transmission with a certain probability.
