Title: Device for forming multilayered thin film by photochemical vapor deposition
Inventor: SUZUKI YOSHIHIKO
IPC: C23C16/48
Filed: 1989-12-25
Abstract: PURPOSE:To stably form a multilayered thin film of desired periodical structure with high precision at the time of forming the film by photochemical vapor deposition by reflecting a part of a laser beam to be used, transducing the light energy into a voltage and thereby adjusting an excimer laser through a pulse generator. CONSTITUTION:An excimer laser beam from an ArF excimer laser 1 is introduced into a reaction vessel 7 to decompose the internal raw gas, and a multilayered thin film in which a heavy element and a light element are alternately and periodically arranged is formed. In this case, a part of the excimer laser beam is reflected by a beam splitter 2 and injected into a calorimeter 3, and the light energy is transduced into a voltage by a thermopile. The transduced value is read by a computer 5 through a digital voltmeter 4 to calculate the pulse rate in order to obtain a specified excimer laser output. The requisite number of pulses are generated by a pulse generator 6, the pulse rate is adjusted to a requisite value as the trigger of the excimer laser 1, and a multilayered film of the desired periodical structures is formed with high precision.

Title: Circuit board and its manufacture
Inventor: FUKUDA MAKOTO
IPC: H05K3/38
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To obtain a circuit board which enhances bonding reliability of a conductor circuit to an insulating layer by a method wherein the face of the conductor circuit on the side of a metal plate comes into contact with the insulating layer via a copper-plated layer and a copper oxide film. SOLUTION: The surface on the side coming into contact with an insulating layer 2 of a conductor circuit 3 comprises a copper-plated layer 4, an oxide film 5 exists on the surface of the copper-plated layer 4, and a circuit board whose bonding reliability is extremely excellent can be obtained. The copper- plated layer 4 comprises a proper uneven surface, a so-called anchor effect is displayed, and the bonding force of the conductor circuit 3 to the insulating layer 2 is increased. In addition, since the oxide film 5 is formed on the surface, its affinity with the insulating layer 2 is increased further when the copper- plated layer 4 and the insulating layer 2 come into contact via the oxide film 5, and their high bonding reliability is achieved.  That is to say, when the oxide film 5 is heated and treated under a condition that it is held, e.g. in the air, at 80 to 200 deg.C for a prescribed time, it is formed on the copper-plated layer 4, and the bonding force of the conductor circuit 3 to the insulating layer 2 is not lowered even after a heat treatment of a humidifying treatment.

Title: Wafer carrier mechanism
Inventor: KANETOMO MASABUMI
IPC: B65G49/07
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To confirm presence or absence of a wafer and confirm also the location by detecting weight when the wafer is mounted on a holder. SOLUTION: Before a wafer 1 is mounted on a holder 22, a plate spring 23 is mounted on the holder 22 and a distortion guage 24 is stuck to this plate spring 23. The tip of the plate spring 23 is made to have a structure that the tip slightly springs out from the upper surface of the holder 22. If the wafer 1 is placed on the holder 22, the lower surface of the wafer 1 and the plate spring 23 come into contact with each other. If the plate spring 23 is made to have a dimension to sufficiently perform deformation by weight of the wafer 1, distortion amount due to the deformation can be detected by a distortion gauge 24. Thus, presence or absence of the wafer 1 on a wafer carrier mechanism can be confirmed and also a prescribed location of the wafer can be confirmed.

Title: Magnetic graduation and its manufacture
Inventor: TSUKAMOTO TAKASHI
IPC: G01D5/245
Filed: 1990-11-30
Abstract: PURPOSE:To enlarge a difference in magnetic property between a base and graduation portion by melting and quenching a preset local point on the surface of the base mainly formed with a perlite layer to form the graduation portion with an austenite and martensite mixed phase. CONSTITUTION:A steel rod as a base is heated at about 900 deg.C, gas-carburized in a carburizing furnace for about five hours and then exposed to air for gradual cool-down to obtain a magnetic graduation steel rod 1 formed with a perlite phase. A laser beam 4 is radiated to a preset local point on the surface carburized layer 2 of the steel rod 1 to melt and graduation portion 3 while carefully viewing it and the melted portion is rapidly cooled down and solidified. As the volume of the melted portion of the carburized layer 2 as the graduation portion 3 is relatively very small, rapid cooling is allowed to form an organization containing sufficiently residual austenite. In this case, if the residual austenite has about 20vol.% or more, it shows a significant difference in relative magnetic property from the base so that the mixture of martensite is allowable up to 80vol.%. Then, the graduation portion 3 is polished to complete the magnetic graduation steel rod 1.

Title: A/d converter
Inventor: SUETAKA HIROYUKI
IPC: H04N11/04
Filed: 1990-11-30
Abstract: PURPOSE:To simplify an analog circuit by converting plural analog input signals to digital data in a time division with an A/D converter, processing this digital data converted in a time division with a logic circuit and obtaining the data in a desired timing. CONSTITUTION:In the case of deriving the data in a necessary timing, for instance, the timing of An from the data An-1, Bn-1, Cn-1, An, Bn, Cn... subjected to A/D conversion by different timings, An is used as data DA as it is, (Bn-1+2Bn) obtained by adding Bn-1 preceding by two of An and 2Bn doubling Bn succeeding by one of An is used as data DB, and (2Cn-1+Cn) obtained by adding 2Cn-1 doubling Cn-1 preceding by one of An and Cn succeeding by two of An is used as data DC. In such a manner, data in a necessary timing can be derived by interpolation from the data subjected to A/D conversion by different timings. Thus, by executing the interpolating executed by a logic circuit instead of a sample-holding circuit, an analog circuit is simplified, and S/N is improved.

Abstract: PURPOSE:To achieve a uniform development and prevent falling-off of a substrate due to surface tension of a developer by enabling a light-sensitive film which is subjected to exposure treatment on the substrate and the developer to contact each other securely over the entire region to be developed by a porous plate. CONSTITUTION:A porous plate 1 is installed horizontally over the entire surface of the upper part of a developer storage bath 8 which is placed at the lower part of a wafer 3. The porous plate 1 has a slightly larger diameter than the wafer 3 and is in disc shape and has an area for fully covering the entire region to be developed of the wafer 3. Then, the developer is made seep onto the upper surface of the porous plate 1 for forming a layer L of the developer on the entire surface of the porous plate 1, thus enabling the light-sensitive film surface to contact this developer layer L. Thus, the entire region to be developed is allowed to contact the developer positively, thereby preventing air bubbles from being generated, achieving a uniform development, and preventing falling-off of the substrate due to surface tension of the developer even if the substrate is retained by a vacuum absorption system chuck.
