Title: Projection aligner
Inventor: KAMON KAZUYA
IPC: H01L21/027
Filed: 1989-12-08
Abstract: PURPOSE:To prevent the occurrence of irregularities in strength of light even if coherence is approximate to 0 by changing the areas of openings, and thereby changing the coherence of an optical system. CONSTITUTION:A plurality of openings 21-23 are provided in an aperture 3. The openings 22 and 23 have meshes whose roughnesses are different. The areas of the openings are adjusted based on the roughnesses of the meshes, and the coherence is changed. That is, when the radius of the opening is reduced, the intensity of the light in the vicinity of a chip is decreased, and irregularities in intensity occur. Since the areas of the openings are reduced by the suitable meshes or dots at this time, the optical system whose coherence value is small without irregularities in intensity is obtained. Therefore, even if the coherence is approximated to 0, the occurrence of irregularities in intensity distribution of light on a wafer is prevented.

Filed: 1987-12-17
Abstract: PURPOSE:To realize a position correction mechanism with a simple structure and thereby make a screen printing machine by correcting a position of a base plate in Y direction and a position in theta direction using a plurality of correction elements provided on a support means which supports a suction table. CONSTITUTION:Correction elements 15, 16 are actuated by driving the first and second correction motors 17, 18 until marks M, M are identified by identification cameras 20, 21 at a specified position. In this way, the position of a suction table 7 is corrected in a Y direction and a theta direction by operation of correction elements 15, 16. That is, the correction in the theta direction is made by a difference between a correction value Y1 obtained by the correction element 15 and a correction value Y2 by the correction element 16. Consequently, a positional shift of a base plate 6 in the Y and theta directions is corrected. After this, the correction elements 15, 16 are separated from engagement members 12, 13 by operation of the correction motors 17, 18 after the suction table 7 is fixed to a support table 8. The support table 7 is sent to a screen printing part 22 by means of an X direction drive motor 19 following the correction of the position in the Y direction. The feed value of the support table 7 as described above is adjusted in accordance with a shift value identified by the identification cameras 20, 21 and the base plate 6 is correctly set to a specified position in the screen printing part 22.

Filed: 1987-12-18
Abstract: PURPOSE:To make it possible to perform epitaxial growth in the state the occurrence of slip is suppressed even if the diameter of a water is large and to make it possible to implement the wafers for high quality VISI substrates, by providing an infrared-ray emitting source away from silicon wafers placed in a reaction furnace. CONSTITUTION:A rotatable susceptor 2 is disposed at an upper part in a quartz bell jar (reaction furnace) 1. An infrared-ray emitting source 3 is disposed at a lower part. A heating coil 4 is disposed at a lower part of the infrared-ray emitting source 3. It is preferable that the susceptor 2 holds silicon wafers 5... with the mirror surfaces of the wafers 5... down. As the material of the emitting source, materials which can emit infrared-ray whose intensity hardly changes even if silicon is deposited on the surface with the progress of an epitaxial process are desirable. For example, carbon graphite or carbon graphite which is coated with SiC is used. Since the infrared-ray emitting source 3 is provided at the position separated from the wafers 5 and the infrared rays are used as the heating source for the wafers, slip is hard to occur in the wafers in comparison with a conventional method.

IPC: H02P5/46
Filed: 1989-12-12
Abstract: PURPOSE:To prevent occurrence of over or under voltage in a DC circuit at the time of abrupt acceleration or deceleration by adding output power to a voltage control circuit in the control system for a phase control rectifier thereby performing feedforward control. CONSTITUTION:A speed control circuit 6 receives a difference between the speed of an induction motor 4 and a speed reference and produces a torque reference which is provided to a subtractor 11 in order to obtain a torque current reference. The torque current reference is provided to an inverter control circuit 7 and a multiplier 12, and the torque reference of the induction motor 4 is multiplied by the terminal voltage to obtain the output power of an inverter 3. The output power is then added to the output of a voltage control circuit 8 thus obtaining the current reference of a phase control rectifier 1. Input corrent to the phase control rectifier 1 is proportional to the output power of the inverter 3. Consequently, powering and regenerating state of the induction motor 4 can be subjected to feedforward control based on the current reference derived from the torque current reference. By such arrangement, occurrence of over or under voltage in the DC circuit can be prevented at the time of abrupt acceleration or deceleration.

Title: Probe equipment
Inventor: KONO RYUJI
IPC: G01R31/28
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To enable excellently following a probe forming surface even when the total pressing load is increased in order to collectively and simultaneously inspect a large region, by arranging pressing mechanism constituted of a plurality of springs and a function which bears reaction to pressing and cancels the effect after contact with a wafer, in the part directly above. SOLUTION: It is explained about the state that a wafer 1 has not been in contact with a probe 31. The wafer 1 is obliged to be slantingly mounted on a probe equipment. In the probe equipment, a reaction bearing mechanism 36 prevents the drop of a pressing board 33, against the force that spring mechanism 35 presses the pressing board 33 downward. By this relation, the pressing board 33 is stabilized, and tension is not applied to a thin film. It is necessary that the reaction bearing mechanism 36 has at least probe 31 pushing-up amount of the wafer 1, i.e., operational margin d1 , d2 which are larger than or equal to stroke amount. After the wafer 1 is brought into contact with the probe 31, inconvenience is not generated since mechanism for cancelling the effect of bearing is arranged.

Abstract: PURPOSE:To obtain a dryer in which clothing or the like is not made wet with water drops again after drying is completed, by setting a water bearing section for storing water flowing through the internal surface of a cover, near the side of a rotary shaft on the internal surface of the cover. CONSTITUTION:When water content evaporated from clothing or the like under drying comes in contact with the internal surface 7a of a cover 7, then the temperature of the internal surface 7a approximates an ambient temperature, and so steam is cooled, and is condensed on the internal surface 7a, and is turned into water drops to be attached to. When the cover 7 is opened in order to take out the clothing or the like after it is dried, then the water drops attached to the internal surface 7a flow to the lower side of the cover (in the direction of an arrow head A), and flow into a water bearing groove 7b, and are collected. Besides, when the cover 7 is closed after the taking-out of the clothing is completed, then the water collected in the water bearing groove 7b has the angle of theta directed upward to the horizontal direction, and so the water is automatically dropped in the direction of an arrow head B. Accordingly, self cleaning can be performed.
