Abstract: PURPOSE:To enhance the quality of a semiconductor device by a method wherein a through hole is made at the bottom of a groove into which a wafer is inserted and by which the wafer is supported so that the thickness of a grown film on the wafer coming into contact with the bottom of the groove can be made equal to the thickness of the grown film on the remaining surface of the wafer. CONSTITUTION:The following are installed: two parallel bars 2a, 2b; two or more grooves 3 which are made on the bars 2a, 2b in order to support two or more wafers 1 at the bars 2a, 2b; and through holes 4 which are made at the respective grooves 3, The grooves 3 are made at the bars 2a, 2b in the following way: their bottom faces are decided by a plane where two lines connecting the center O of the wafer 1 with each of points A1, A2, at which the periphery of the wafers 1 comes into contact with the periphery of the bars 2a, 2b, cross at right angles; and two or more wafers 1 can be supported in nearly parallel with one another after they have been inserted into the grooves 3. The through holes 4 are made at the bars 2a, 2b at their bottom faces of the grooves after two straight lines OA1, OA2 corresponding to their respective wafers 1 have been decided as their centers. Accordingly, a gas creeps into the through holes 4 and is exchanged through them; it is possible to make the thickness of a grown film on the wafers coming into contact with the bottom face of the grooves equal to the thickness of the grown film on the remaining surface of the wafer.

Title: Production of sintered body made of amorphous alloy powder
Inventor: KIMURA HIROSHI
IPC: C22C1/04
Filed: 1990-03-15
Abstract: PURPOSE:To produce the high-density sintered body which is suitable for production and working of magnetic parts by sealing amorphous alloy powder into a vacuum capsule and heating the capsule to a crystallization temp. or below, then subjecting the capsule to hot isotropic pressing. CONSTITUTION:The amorphous alloy powder is produced by a mechanical ironing method or mechanical gliding method. This alloy powder is sealed into the capsule which is internally evacuated. The capsule is then heated to the temp. lower by 100 deg.C than the crystallization temp. and below the crystallization and is subjected to the hot isotropic pressing within this temp. range, by which the sintered body is obtd. The crystallization of the amorphous alloy is prevented in this way. Since the sintered body is of a high density and is maintained in the amorphous state, the sintered body having high performance is produced as the magnetic parts. The high strength is thus obtd. and the machining of the parts is possible.

Title: Semiconductor manufacturing equipment and process tube for reaction chamber
Inventor: KAWACHI NOBUTAKA
IPC: H01L21/205
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent the appearance of defective wafers by suppressing the generation of a deposit in a pipe or a gas intake port due to reverse diffusion. SOLUTION: At a gas intake port 2a, (2b), an orifice 20 is formed which has such a diameter that reverse diffusion of reaction gas from a reaction chamber 1 side to the gas intake port 2a, (2b) can be prevented, based on the flow rate or the composition ratio of reaction gas, the pressure in the reaction chamber 1 and the like. When reaction gas is introduced into the reaction chamber 1 with air being sucked by an air suction port 15, the pressure is higher on the downstream side of the orifice 20 than on the upstream side, and therefore there is no reverse diffusion on the upstream side of the orifice 20.  Since a region where there is a possibility of a deposit becomes narrower, the production of a deposite can be reduced, Furthermore, a deposite can be removed relatively easily on the downstream side of the orifice 20 of the gas intake port 2a, (2b) and thereby the deterioration in the quality of a wafer caused by the blowout of a deposite can be prevented.

Title: Method for inputting image and device therefor and electronic camera
Inventor: FUNATO HIROYOSHI
IPC: H04N5/335
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To fetch a document image with high resolution. SOLUTION: An operation for forming an image of crisscross divided images of an object 4 deflected by the movable mirror 5 each time a movable mirror 5 is inclined to a two-dimensional direction on a two-dimensional solid-state image pickup element 2 by an image forming optical system 3 is repeated plural times so that the picture of the subject 4 can be crisscross divided and fetched. Then, the divided images of the object 4 fetched each time are connected so as to be synthesized in one image. Thus, resolution can be improved without increasing the number of picture elements of the two-dimensional solid image pickup element 2 even in the case of a document image.  Also, the image area of the subject 4 is divided so that the generation of any distortion or focal blur in the peripheral part of the image can be prevented by condensing the picture of the subject 4 on the movable movable mirror 5 by a condenser optical system 6 even when the inclination of the movable mirror 5 to the subject 4 is large at the time of inclining the movable mirror 5.

Title: Mos amplifier circuit
Inventor: SATOU KATSUYUKI
IPC: H03K3/356
Filed: 1984-04-06
Abstract: PURPOSE:To enhance gains of a main amplifier in a dynamic RAM with simple constitution by feeding back positively differential amplification outputs to FETs which cross and couple mutually through a current mirror circuit. CONSTITUTION:When an FETQ5 is turned on in such a condition that the reading levels of one common complementary data line CDL, etc., are higher than the other anti-CDL, etc., a current flowing in an FETQ1 becomes larger than that of an FETQ2. These currents are gain-amplified by a group of FETs Q6 and Q7 and that of Q8 and Q9, respectively, and fed back positively to the FETQ2 and Q3, which cross and couple mutually. As a result, gains of a MOS amplifier circuit are enhanced by the synergistic effect of the high gain amplification and the positive feedback, and gains of a main amplifier, etc., in a dynamic RAM can be improved with simple constitution.
