Title: Bonding method
Inventor: YAMAMOTO AKIHIRO
IPC: H01L21/52
Filed: 1986-11-20
Abstract: PURPOSE:To make it possible to perform correct working, by detecting the position of the tip of a tool by a measuring means, which is fixed at a specified position, positioning the tip at an original point, comparing the position data of the tool at that time with a preset value, and moving and controlling the tool based on the position data, whose errors are corrected. CONSTITUTION:When a nozzle is changed in a die bonding apparatus, the position of the tip is changed. At first, the tip of a tool 10 is moved to the vicinity of an original point O. The tip of the tool is detected by a means 15 and finely moved. The tip is made to agree with the original point O, and the position data of a control part in the direction (z) is corrected with the position data of the tip. The position data in the directions (x) and (y) are corrected by the same way. Then the normal die bonding operation is resumed. When the position of the tool, which is obtained by the position measuring means in this constitution, is compared with the preset position data and the errors are automatically corrected; the working time is shortened, and the working errors are excluded.

Title: Method and apparatus for x-ray exposure
Inventor: KAWASHIMA KENICHI
IPC: H01L21/027
Filed: 1984-12-26
Abstract: PURPOSE:To enhance exposure efficiency and enable the increase of throughput by giving exposure treatment that involves the displacement of a X-ray beam relative to both of the sample to be exposed and the mask, and in the direction of the short side of the radiation field, namely, in the lateral direction of the V-shaped groove for the purpose of giving the optimum contour of the radiation field. CONSTITUTION:A target 1 rotates with a high speed along the circumferential direction of the groove 2 having a V-shaped cross-section. A sample to be exposed 4 is placed on a stage 3 below the target 1 and a resist film 5 is formed by coating on the surface of the sample, above which a mask 6 is supported. A part of the X-ray source containing the target 1 undergoes reciprocating motions in the direction crossing the V-shaped groove 2, namely, that of the rotation axis of the target 1. The reciprocating a motions are uniform motions which are set to repeat reciprocations at least once an exposure. The X-ray beam 7 is shifted every reciprocation to form a roughly circular intensity distribution of X-rays. As the results, the effective radiation field forms a square, enabling effective exposures.

Title: Electromagnetic rotating device
Inventor: KIYOUTANI HIROTOMO
IPC: F16C32/04
Filed: 1987-11-02
Abstract: PURPOSE:To increase the primary bending natural frequency of a rotor shaft to make its high speed rotation possible by arranging one core coil on a radial outside of the other core coil, and partially overlapping the coils each other in their axial direction to shorten a rotating body. CONSTITUTION:A coil 13b of the primary radial electromagnet 13 is arranged on the radial outside of a coil 12b of a motor stator 12 and a coil 15b of the primary radial sensor 15, and partially overlaps with the coils 12b, 15b in its axial direction. A coil 14b of the secondary radial electromagnet 14 is similarly arranged on the radial outside of the coils 12b, 16b, and partially overlaps with the coil 12b, 16b in its axial direction. The summed up axial length of the stator 12, the electromagnets 13, 14 and the sensors 15, 16 can therefore be made shorter than their ordinary length, and a rotor shaft 11 can be shortened by the above-mentioned shortened length. Thus the primary bending natural frequency of the rotor shaft 11 increases to make its high speed rotation possible.

Title: Method and apparatus for production of thin film
Inventor: MEGURO SUSUMU
IPC: H01L41/39
Filed: 1990-10-16
Abstract: PURPOSE:To allow the independent taking out of a thin film and the prevention of the failure thereof by solidifying liquid while applying a pressure stop the thin film and thereby forming the thin film at the time of forming the thin film. CONSTITUTION:A material for forming the thin film is dissolved in a developing solvent and the pure liquid is put into a hermetically closed liquid housing container which is divided to at least two chambers. A soln. prepd. by dissolving a material for forming the thin film diluted in a solvent is dropped onto the liquid to form the thin film. The liquid in the liquid housing container is cooled to solidify while an air pressure is applied to the liquid surface and thin film surface in the hermetically closed chamber where the thin film is formed. The thin film is thereafter peeled from the surface on which the liquid is solidified. The thin film is thus formed. The liquid is cooled and solidified while the contact surface of the water and the thin film is smoothed and, therefore, the thickness of the film surface can be changed by adequately adjusting the intensity of the pressure to be applied on the film surface. In addition, the film having the smooth surface is formed by dissolving the bubbles, etc., on the liquid surface into the liquid. The peeling of the thin film formed on the liquid surface is facilitated by cooling the liquid to solidify.
