Title: Bonding method for semiconductor element
Inventor: KIYOZUKA KOUICHI
IPC: H01L21/58
Filed: 1978-01-18
Abstract: PURPOSE: To secure the highly reliable junction by giving the gold-Si eutectic only at the pellet junction time and then stopping forcedly the progress of the eutectic after the junction.  
     CONSTITUTION: Gold foil 5 is provided on tab 4, and then pellet 6 is put on the foil to be heated up. At the same time, the pellet is pressed from above with rubbing. The whole pellet is heated up to 380°C or more to form gold-Si eutectic layer 7. The N 2  gas of the normal temperature is jetted 8 right after the eutectic state is obtained, and the temperature of under the eutectic is secured within one second. The progress of the eutectic is suppressed by the sudden decrease of the temperature, reducing greatly the thickness of the alloy. As a result, the useless diffusion of the gold can be avoided into Si, and thus the minute cracks can be eliminated at the pellet sealing part. This results in enhancing the reliability of the products.

Title: Method for forming joined body of metallic plate and ceramic target and ceramic thin film
Inventor: SUMIYA KEIJI
IPC: C04B37/02
Filed: 1989-01-10
Abstract: PURPOSE:To provide the subject joined body, excellent in joining strength and suitable for producing ceramic thin films without causing warpage and peeling of a joined part by joining a metallic plate to a ceramic target with a solventless silicone adhesive containing specific powder added thereto. CONSTITUTION:One or more of powders selected from silver, copper, boron nitride and aluminum nitride are added to a solventless silicone adhesive. The resultant adhesive is then used to join a metallic plate to a ceramic target (e.g. Y-Ba-Cu-O-based superconducting ceramics). The obtained joined body of the metallic plate and the ceramic target is subsequently mounted on a sputtering device to discharge the ceramic target and form a ceramic thin film on the surface of a material. Thereby, the ceramic thin film can be produced without causing peeling of the joined part between the metallic plate and the target, cracking of the target surface, etc.

Filed: 1983-01-17
Abstract: PURPOSE:To make fine processing easy and at the same time make formation of ohmic electrode of good reproducibility by cleaning a surface of a semiconductor utilizing a physical sputtering action of a low-energy Ar ion beam. CONSTITUTION:After a surface of a semiconductor is cleaned by an etching by a low energy, for instance 50 eV, Ar ion beam, an Au.Ge/Ni/Au 3 is deposited on the surface and annealed in an atmosphere of H2 gas of the air pressure at 450 deg.C for about one minute. And an electrode is formed by depositing an electrode material which makes ohmic junction with the semiconductor. The annealed surface of the n-GaAs 2 is sputtered physically by inert Ar ion and is very clean so that the ohmic electrode, formed by depositing the Au.Ge/Ni/Au 3 on this clean surface and by processing it by thermal treatment, provides an ohmic junction of good reproducibility. A damage of several hundred Angstrom  depth is given on the surface when the GaAs surface is cleansed by sputtering. A degree of the damage becomes very slight in accordance with reduction of the kinetic energy of the sputtering ion and the damage on the GaAs surface caused by the Ar ion of 50 eV is cured by annealing in an atmosphere of N2 gas of the air pressure at 300 deg.C for 20min.

Title: Method for mask alignment
Inventor: KIMURA TATSUYA
IPC: H01L21/30
Filed: 1985-01-16
Abstract: PURPOSE:To effect the mask alignment easily when a level difference on a sample is small by minutely adjusting with the sample put on a sample table after placing a mask and the table by the placing board having a large level difference. CONSTITUTION:A mark 6 having a level difference of about 10<3>Angstrom  is formed in the center of a placing board 5. A glass mask 3 is set on a matching device and the board 5 is mounted on a sample table. The center pattern 4a of the mask is adjusted to the mark 6 of the board 5. Since a level difference of the mark 6 is large, matching is easily done by low magnification of a microscope. The sample 1 is put on the table and is transferred. In a case of the mask alignment after various processes, as a level difference is reduced, at first the glass mask 3 and the placing board 5 are mounted and matched by viewing with low magnification. Next, the sample 1 is mounted and viewing with high magnification is done to match a measurement pattern 2 of the sample 1 to a measurement pattern 4a of the mask 3. Thus the mask alignment can be easily by a narrow field of vision.

Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To perform recording while varying a sheet stably up to the rear end thereof by disposing a recording head on the downstream side in the sheet carrying direction of a platen and a pressure roller formed, at least the circumferential surface thereof, of an elastic member and the charging the sheet thereby carrying the sheet while attracting. SOLUTION: When a pressure roller 3 is pressed against the circumferential surface of a platen 2, the elastic part (silicon rubber 12, 14) of the platen 2 and the pressure roller 3 is deformed elastically. Consequently, when a sheet 1 is passed between the platen 2 and the pressure roller 3, a nip part is shifted by through distortion of the elastic members 12, 14 to generate friction between the silicon rubber 12, 14 and the sheet 1 which is thereby charged. The charged sheet 1 delivered from the platen 2 and the pressure roller 3 along a guide plate 5 while being attracted thereto and caught by a carrying roller 6 before being neutralized through a neutralization brush 7 and discharged.
