Title: Method of wafer alignment with reducing projection aligner
Inventor: YAMAGUCHI TOSHIYA
IPC: H01L21/30
Filed: 1990-06-18
Abstract: PURPOSE:To avoid the degradation in asymmetry of alignment marks and the degrada tion in an alignment accuracy by a method wherein only the alignment marks which are so provided as to have their longitudinal directions directed toward the center of a wafer are used. CONSTITUTION:X-direction alignment marks 3A whose longitudinal directions are directed toward the center of a wafer 7 are scanned by a He-Ne laser beam 2A whose spot has an oblong shape. The longer diameter of the spot of the laser beam 2A is shorter than the longitudinal length of the X-direction alignment mark 3A by about 1mum. The signal intensity of a diffracted an scattered light beam produced by scanning is varied and an X-direction position is calculated. Then, in order to obtain a Y- direction position, the X-direction alignment marks 3A are scanned several turns while the laser beam 2A is shifted by a certain interval at every turn. The signal intensity of a diffracted and scattered beam is varied and the position on an X-axis where the maximum peak value is detected is obtained to obtain the Y-direction position. An alignment correction value, expansion and contraction, a perpendicularity, a rotation and a position deviation can be obtained only by the information of the alignment marks whose longitudinal directions are directed toward the center of the wafer.

Abstract: PURPOSE: To minimize loss amount as far as possible, prevent the occurrence of underweight products and improve yield by determining a minumum required ingot cutting length for each of the ingots to be cut from the strand which is extracted from a continuous casting machine.  
     CONSTITUTION: Molten steel in a ladle 1 is led via a tundish 2 to a mold 3, and the pass length of a formed strand 4 is measured with a measuring device 5, then it is cut with a cutter 6 and the cut ingots are carried out. In this case, the strand 4 is dividedly recognized as multiple small areas in which the drawing length is (l) shorter than the anticipated cutting length, and the movement of each small area is tracked from the time when it was cast until it is cut out as an ingot of a required length with the cutter 6. At the instant when the leading end of the strand 4 first reaches the measuring device 5, the specific region of a memory device 7 is assigned for every small area of the length (l) from that leading end and the codes specifying the small area are corresponded. Thereafter, at every drawing of the strand by (l), this is recognized by the output data of the measuring device 5, and a new region is assured for the new small area formed on the mold 3 side.

Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To output video signals for which pixels are thinned out by switching the processing amount of a processing amount variable video processing means and sending the output to a video output terminal. SOLUTION: By the detection of a video cable pull-off state, a video cable insertion/detachment detector 14 outputs first signals and sets linked switches S2a and S2b to a solid line position. Thus, the video signals in a PDMix mode obtained from a CCD 4 are sent through an A/D converter 6, a first processing circuit 10 and a D/A converter 22 to a liquid crystal display device 26 provided in a camera main body. The first processing circuit 10 thins out many pixel signals and performs picture processing. Also, by the detection of a video cable insertion state, the video cable insertion/detachment detector 14 outputs second signals and sets the linked switches S2a and S2b to a dotted line position. Thus, the video signals in the PDMix mode are sent through the A/D converter 6, a second processing circuit 12 and the D/A converter 22 to a monitor display device 28.  The second processing circuit 12 thins out relatively few pixel signals and performs picture processing.

Abstract: PURPOSE:To remove water drops deposited on a board-like member nearly uniformly over the whole face of the board-like member by fixing an oscillator having an annular electrostrictive element to a part of the swingably supported board-like member and oscillating the oscillator to repeatedly bend the board- like member. CONSTITUTION:A piezoelectric oscillator 20 in which electrodes 21, 22 are integrally provided on both end faces of an annular electrostrictive element 24 is fixed nearly to the center portion of the mirror 11 of each vehicle side mirror by means of an adhesive. The electrodes 21, 22 are connected to an oscillating circuit via lead wires 31, 32 and AC power is applied to the piezoelectric oscillator 20, expanding/contracting same in the thickness and radial directions to repeatedly bend the mirror 11. Thereby, water drops deposited on the surface of the mirror 11 are shaken off and removed. In this case, the frequency of the AC power is selected to be in the vicinity of the integral multiples of the minimum resonance frequency of the mirror 11 to resonate the mirror 11, thereby generating uniform standing waves with a large amplitude on the whole mirror 11 to improve the removing efficiency of water drops.

Abstract: PURPOSE:To constitute the titled reader so that a user can confirm visually without fail even a small character, by bringing a mobile base to a moving control, when a character which cannot be read exists, and irradiating its character by a spot light. CONSTITUTION:The titled reader can be manufactured at a comparatively low cost since an image sensor 1, etc. are provided on the mobile base 10 of a printer, and the read data of one character is compared with a data stored in advance in a character data storage part 32 and discriminated by a comparing and discriminating part 31. Also, when reading program, etc. of an original 20 by the image sensor 1, if a character (containing a symbol, as well) which cannot be read exists, the mobile base 10 stops the reverse, and the character which cannot be read is irradiated by the light emission of an LED 5 by using the colors of red, green, etc., therefore, the character which cannot be read can be confirmed visually without fail, and an input can be executed quickly from a keyboard part (containing a touch panel, etc., as well). Also, the light of the LED 5 irradiates the character which cannot be read exactly by a block cursor-shaped form, therefore, even in case of a small character, a character to be inputted can be known without fail.

Title: Manufacture of semiconductor device
Inventor: ITO RYOICHI
IPC: H01L29/73
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To prevent a diffusion layer parasitic capacity from increasing by forming a P-type diffusion layer that also plays a role of the side surface collector region of a vertical PNP transistor by forming a vertical groove through etching and by performing filling with a polycrystalline silicon layer, including a diffusion impurity for decreasing resistance. SOLUTION: A P-type diffused layer 3' of the entire portion of the surrounding part of the side surface collector region of a vertical PNP transistor is formed by performing the vertical groove etching of an N-type epitaxial layer 2 until a P-type embedded layer 3 is reached and further filling a polycrystalline silicon 23 whose resistance is decreased containing the P-type diffusion impurity. Therefore, the diffusion spread in the horizontal direction is determined less by the width of a groove 20 formed by the vertical groove etching, as compared with a case when a side surface collector region is formed due to thermal diffusion, thus suppressing the increase in the diffusion layer parasitic capacity of the side surface collector and improving the cut-off frequency of the vertical PNP transistor.

Abstract: PURPOSE:To prevent the rechargeable battery from excessively being discharged by stopping the power supply to the cold storage fan motor upon detecting the temperature of the heat storage material, and stopping the operation of the fan motor at a predetermined level of discharge capacity by counting the fan motor operation time. CONSTITUTION:When all the heat storage material melts, both the cabinet temperature A and heat storage material temperature B rise. If the temperature of the heat storage material at a moment t3 becomes higher than the set temperature T3 due to the fact that the ambient temperature is high, the heat storage material temperature detecting means 13 goes off to stop the power supply from a rechargeable battery 10 to a fan motor 7. If the ambient temperature is low, a cumulative timer 14 determines the time for starting the operation of the fan motor 7, and switches off its contact point 14a at the predetermined elapsed time. The cumulative timer 14 is reset when the power supply via lead wires 14b, 14c is ceased, that is, when the cold storage switch 11 goes off.
