Title: Baking treatment of resist coated film
Inventor: MIMURA YOSHIAKI
IPC: H01L21/027
Filed: 1988-06-29
Abstract: PURPOSE:To obtain a stable resist film by coating a film essentially consisting of a cresol novolak resin and o-naphthoquinonediazide photosensitive agent on a substrate and irradiating the film with weak UV rays while heating up the film gradually and further by irradiating the film with strong UV rays. CONSTITUTION:The positive type photoresist film essentially consisting of the cresol novolak resin and the o-naphthoquinonediazide photosensitive agent is coated on the semiconductor substrate and thereafter, while the substrate is gradually heated up, the film is irradiated with the weak UV rays to photodecompose the photosensitive agent. The film is in succession irradiated with the strong UV rays to effect a crosslinking reaction and to cure the film. Further, this positive type photoresist film is irradiated with the weak UV rays while the substrate is slowly heated up in succession to the coating of the film to photodecompose the photosensitive agent. The generation of bubbles in the resist film to adversely affect the production yield of integrated circuits and electronic devices is suppressed in this way and the resist film having the excellent surface smoothness and mechanical and thermal stability is obtd.

Title: Circuit for stabilizing light-source wavelength
Inventor: OKADA KENICHI
IPC: H01L33/00
Filed: 1986-07-09
Abstract: PURPOSE:To eliminate the reference light source such as He-Ne laser with stabilized wavelength simplifying the structure for making it compact and lightweight by a method wherein the photowavelength of a light source is controlled to be almost constant by control signal from a fluctuation detecting means. CONSTITUTION:The light from a light source (wide band longitudinal mode) 38 enters a Michelson interferometer 46 to be bisected and is divided into two components by a photodistribution coupler 47. The respective components are reflected by edges 51, and 52 and combined with each other again by the coupler 47 before reaching a photodetector 53. The intensity of interfered light is photoelectrically converted by the photodetector 53 and compared with the reference signal from a reference power supply 55 by a comparator 54. If the temperature in light source 38 is raized by any cause and the wavelength of light increases, the intensity of interfered light is increased and the photoelectric conversion signal is enhanced, thereby causing the comparator 54 to produce a negative erroneous signal. The negative erroneous signal from the comparator 54 is integrated by an integrator 56 and transmitted to a temperature controller 57 lowering the temperature of light source 38. Resultantly the wavelength of light emitted from the light source 38 can be shortened.

Title: Ic lead frame
Inventor: MIYAMOTO KOJI
IPC: H01L23/50
Filed: 1989-06-22
Abstract: PURPOSE:To eliminate the sag of a loop at the time of wire bonding process without changing the manufacturing method of an IC lead frame, by starting coining process for correcting material deformation at the time of punching, from the interior of an inner lead tip. CONSTITUTION:The tip part of a gold wire 4 is formed in a sphere type, which is pressed against a semiconductor element 3 with a bonding tool 6 fixed to a horn 5. After bonding is performed by applying heat and ultrasonic wave, a loop is formed while the gold wire 4 is sent out from the bonding tool 6. When the bonding tool 6 is pressed against the tip of the inner lead 2, a point 7 is retained and the loop is formed, which point serves as a fulcrum when a part 2b at the tip of the inner lead 2, which part has not yet been subjected to coining, forms the loop. After that, the horn 5 is lifted while grasping the gold wire 4, thereby tearing off the gold wire 4. The tip of the tore gold wire 4 is turned into a sphere type. Thereby stable loop formation is enabled at the time of wire bonding without changing the conventional manufacturing method.

Title: Rolling method for pure titanium material
Inventor: YAMASHITA SUMIO
IPC: B21B3/00
Filed: 1987-06-30
Abstract: PURPOSE:To prevent the generation of surface flaw by regulating a rolling starting temp. to a specified low temp. zone and regulating a finish rolling temp. to over a specified temp. CONSTITUTION:An industrial pure titanium (purity: >=99wt.%) is used as a blank rolling material and it is heated to 500-800 deg.C, the rolling temp. is set 500-700 deg.C, then the hot rolling is performed at the finish rolling temp. to be over 450 deg.C. In this stage, the upper heating temp. of the blank material is limited to 800 deg.C, for suppressing the generation of oxidized scale. As for the rolling starting temp., when it is <500 deg.C, the rolling is difficult because its deforming resistance is too large and when it exceeds >700 deg.C, the surface flaws such as craters, bald spots etc., are increased. Furthermore, when the finish rolling temp. is 450 deg.C, the rolling is difficult because the deforming resistance becomes too large. In this way, the surface flaws are significantly reduced and an excellent rolling is performed.
