Title: Etching technique for metallic film
Inventor: AKAZAWA KAZUHIKO
IPC: H01L21/302
Filed: 1992-03-25
Abstract: PURPOSE:To control the wafer transmittance of a wafer patter surface, and to inhibit dispersion after etching due to the difference of a metallic-film pattern by setting the wafer transmittance of a reference pattern section for etching at a fixed value. CONSTITUTION:Reference patterns 4 for etching are formed previously onto all pattern surfaces of a metallic-film pattern forming wafer 5, an etching sensor 1 and a slit 3 are set so that sensor light 2 emitted from the etching sensor 1 is hit only on the reference patterns 4 for etching through the slit 3, and the metallic-film pattern forming wafer 5 is rotated and etching operation is conducted. The transmittance of the reference patterns 4 for etching is sensed by the etching sensor 1 at that time, and the transmittance of the patter surface of the metallic-film forming wafer 5 as an object to be etched must also reach a normal value when the transmittance previously reaches a fixed value. Accordingly, the dispersion of the states of the patterns after etching can be prevented even when the metallic-film patterns differ.

Title: Purification of solid phase and antibody
Inventor: FUJITA ISAO
IPC: C07K16/00
Filed: 1982-04-21
Abstract: PURPOSE:To advantageously recover an anti-human chorionic gonadotropin antibody (anti-hcG antibody), by a method wherein a liquid containing a crude anti-hcG antibody is brought into contact with a solid phase supporting crude protein derived from human serum or human urine. CONSTITUTION:A liquid containing a crude anti-hcG antibody is brought into contact with a solid phase supporting crude protein derived from human serum or human urine. By this operation, because an antibody other than the anti-hcG antibody coexistent in the liquid containing the crude anti-hcG antibody is absorbed by the solid phase and only the anti-hcG antibody is not absorbed, anti- hcG antibody is advantageously recovered. The liquid containing the crude anti- hcG antibody used in this method is obtained by a method wherein a stock liquid containing said anti-hcG antibody is for example brought into contact with a hcG-supporting solid phase and an anti-hcG antibody part is subsequently eluted. As hcG in the hcG supporting solid phase and hcG used in preparing the anti-hcG antibody part, hcG obtained by purifying commercially available hcG obtained from the urine of a pregnant woman to about 8,000-10,000IU/mg is used.

Title: Formation of soi crystal
Inventor: EGAMI KOUJI
IPC: H01L21/20
Filed: 1984-04-05
Abstract: PURPOSE:To improve the controllability by grooving the surface of Si film and scanning the laser beam parallel with the groove, after the Si film is deposited on an insulation substrate. CONSTITUTION:The polycrystal Si film 2 is deposited on the quartz glass substrate 1 and the groove 3 is worked. In case which the groove with depth X is installed on the Si film, the thickness of this film is (t-x), the formula 2n(t- x)=Nlambda is satisfied within the error of 1.9% if 7 is selected an integral number N. That corresponds to min. of the reflection interference peek as compared with the wavelength of argon laser. Accordingly, the Si film whereon the groove is provided enables to absorb energy per unit of volume more than the non- grooved Si film. Subsequently, if the sample material is heated to 300 deg.C and annealed using CW-Ar<+> laser (wavelength 0.5mum), the crystal grain boundary is found only under the region processed by the groove 3 previously, and then the grain boundary is extended parallel to the groove 3 and the width is corresponded to the cycle L of the groove 3. Thus, the large Si single crystal film has been formed. Owing to this, about 3-5mm. length of single crystal Si film is enabled to be produced, by controlling only the depth of the silicon film.
