Patent JP-H03173125-A (JP)
Title: Manufacture of semiconductor device
Inventor: KAJI SHIGEHIKO
IPC: H01L21/3205
Filed: 1989-11-30
Abstract: PURPOSE:To reduce a contact resistance of an interconnection layer and to form an electrode interconnection whose reliability is high by a method wherein, before a second conductor layer is formed so as to come into contact with the surface of a substrate of a conductor layer such as a first interconnection layer or the like, the surface of the conductor layer is exposed to an atmosphere of a mixed gas composed of hydrogen gas and a gas containing at least one kind of halogen atoms while it is being irradiated with light. CONSTITUTION:An element isolation and insulating film 2 is first formed on the surface of a p-type silicon substrate 1; an element region is formed; then, a diffusion layer 3 is formed. At this time, a spontaneous oxide film 6 is formed on the surface. In addition, a silicon oxide film 4 is formed by a CVD method or the like; a contact hole 5 is made in the film; a resist is stripped off and removed. At this time, the spontaneous oxide film 6 is formed on the diffusion layer 3 at the bottom. The substrate 1 is placed in a vacuum container; a gas atmosphere of hydrogen and chlorine is formed; the diffusion layer 3 and the silicon oxide film 4 are etched when they are irradiated with light of a mercury lamp; the spontaneous oxide film 6 is removed. The substrate 1 is transferred to a CVD apparatus; a tungsten film 7 is filled into the contact hole 5. Thereby, an interconnection layer which is uniform and whose contact resistance is small is formed.

Title: Production of thin-magnetic film
Inventor: SAKAI YUICHI
IPC: G11B5/31
Filed: 1990-11-16
Abstract: PURPOSE:To easily and rapidly expose a magnetic gap surface by etching the rear surface of a substrate near to the depth at which a magnetic gap is exposed and further executing chemical etching again by using an etchant of the etching rate lower than the etching rate thereof. CONSTITUTION:For example, upper and lower magnetic cores 7, 4 are formed of Ni-Fe and a magnetic gap 3 and protective film 2 of a sliding surface of diamond-like carbon. The surface is thereafter polished to flatten and to expose a juncture. An element supporting substrate 10 is adhered and the rear surface of the substrate is immersed into a soln. mixture composed of hydrofluoric acid and nitric acid and is dissolved away at a high speed down near to the depth at which the head element is exposed. The substrate down to the gap surface is removed by using the etchant or precision mechanical polishing which does not affect the head element of the low etching rate and, therefore, the gap surface of the head element is exposed easily and rapidly even if the thickness of the substrate is increased in order to prevent the warp of the substrate arising from the element formation.

Title: Scan conversion executing device for graphic display system
Inventor: LARSON RONALD D
IPC: G06T15/40
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To execute scan conversion for calculating pixel position in a screen space corresponding to a primitive during the scan conversion by converting a specified area into the pixel position in the screen space, when the specified area is decided to exist completely in the primitive. SOLUTION: The screen space corresponding to a display monitor is divided finely into plural N×N areas. Coordinates corresponding to corners of respective N×N areas are judged as to whether or not they exist outside the primitive by using a plane equation corresponding to sides of a first primitive, to which the scan conversion is performed. After that, all the corners of the next area of a level of the screen space are judged whether or not they exist outside the primitive. Then when not all corners of the areas are judged to exist outside the primitive and furthermore, all the corners of the areas are judged to exist in the primitive, the areas are converted into pixels, and the pixels are further transmitted to the downstream side.

Title: Coaxial network transmission equipment
Inventor: OUE YUJI
IPC: H04Q5/00
Filed: 1988-12-12
Abstract: PURPOSE:To increase the using efficiency of frequencies by providing exclusive RF MODEMs for two B channels and one D channel in a terminal adapter, allocating the frequencies only to the D channel and the B channel where signals exist, and allowing only the RF MODEM to actuate. CONSTITUTION:Terminal adapters 103 and 105 respectively consist of a MODEM control part 121, a D channel RF MODEM 122, B1 and B2 channel RF MODEMs 123 and 124, and an interface part 125 of an ISDN terminal 106. The RF MODEMs 122 to 124 can respectively and individually use the arbitrary frequencies out of f0 to fn by the control of a MODEM control part 121. When a terminal 1 uses only the B1 channel, a MODEM control part 110 of a center device 100 instructs the MODEM control part 121 of the terminal adapter of the terminal 1 to use the MODEM 122 at f0 and to use the MODEM 123 at f1, and instructs it not to use the MODEM 124. Thus, only the frequency bands corresponding to the D and B1 are used, and the wasteful use of the frequency band corresponding to the B2 where the signals do not exist can be prevented.

Title: Ultrasonic flaw detection
Inventor: SUYAMA SHOJI
IPC: G01N29/44
Filed: 1990-11-19
Abstract: PURPOSE:To carry out flaw detection enhanced in flaw detection capacity and reduced in erroneous diagnosis by extracting a reflected wave exceeding a specific level from flaw detection data composed of reflected waves obtained by a horizontal wave vertical probe. CONSTITUTION:A ultrasonic flaw detection apparatus 6 drives a horizontal wave vertical probe 5 to perform the transmission and reception of ultrasonic waves and a data recording apparatus 7 records the peak generating time of the flaw detection signal obtained in a time detection part 64 and the echo level obtained in a level converting part 65 as flaw detection data to send out the same to an operational processing apparatus 8. The apparatus 8 performs the time reversal of a signal, subtraction processing and the identification of an echo on the basis of the flaw detection data from the apparatus 7 and the estimation data from an input apparatus 10. When fundamental flaw detection data preliminarily collected and having no flaw is recorded on a recording medium, a data regeneration apparatus 11 reads the data to regenerate the same and sends out the same to the apparatus 8. An output apparatus 9 allows an echo exceeding a threshold level to correspond to the shape of an object to be inspected and outputs whether the echo is generated by a flaw, a shape or noise.

Filed: 1989-12-01
Abstract: PURPOSE:To improve the processing efficiency of the function simulation by providing a signal value storage means and a flag storage means which stores a flag showing that all bits have the same specific value to set the flag when all bits has the specific value and to write each bit if all bits have no specific value. CONSTITUTION:A flag is set to a flag storage means 5 when the signal values having the fixed number of bits to be written into a signal value storage means 4 have the same signal value, e.g., the unfixed value, the high impedance value, 1 or 0, etc. Then only the set-up of a flag is decided at a flag storage means 5 as long as all signal values have the same unfixed value, the high impedance value, 1 or 0 when the signal value having a fixed bit is read out as the input signal value. Thus the function simulation is carried out at a high speed.

Title: Tape sticking equipment for semiconductor wafer
Inventor: HAYASHI ICHIRO
IPC: H01L21/683
Filed: 1986-12-27
Abstract: PURPOSE:To prevent the damage on a surface by forming a supporter which attracts and holds a semiconductor wafer in the periphery and a pressurizer which pressurizes the inner surface of the semiconductor wafer in a noncontact state on a wafer susceptor on which the semiconductor wafer is mounted with the surface facing down. CONSTITUTION:A semiconductor wafer 2 mounted on a wafer susceptor 7 with the surface facing down makes a contact with a supporter 8 only in the periphery of the wafer and is held on the supporter 8 by attracting the semiconductor wafer 2 with a hole 9 for attracting. Then, air is ejected from a nozzle 10 and the inside of a pressurizer 11 is made a pressurized state. In such a state, when an adhesive tape 5 is stuck by the horizontal movement of an adhesive roller 6, the adhesive tape 5 is stuck from the upheaved center of the semiconductor wafer 2 toward the periphery. As a result, the air between the semiconductor wafer 2 and the adhesive tape 5 is smoothly exhausted from the center of the wafer toward the periphery. This can reduce the damage on the semiconductor wafer and the entrainment of bubbles.
