Title: Plasma etching method
Inventor: TANUMA YUKIO
IPC: H01L21/3065
Filed: 1979-10-01
Abstract: PURPOSE: To adequately remove the defect layer of the etched surface by plasma- etching the film of the surface of a semiconductor substrate then subjecting the same repeatedly to oxidation, oxide removal and heavy metal removal treatments.  
     CONSTITUTION: A silicon oxide film, a silicon nitride film for selective oxidation and a resist mask are formed on a silicon substrate or the like, and the silicon nitride film and silicon oxide film are etched by using a CF 4 +H 2  gas etc. This etched surface is subjected to oxidation treatment by using sulfuric acid + hydrogen peroxide solution or the like, thence the thus formed oxide film is removed by using a dilute hydrofluoric acid or the like. In succession to this, the remained heavy metals are removed by using aqua regia. This operation is repeated several times. The induction of huge crystal defects called "stacking fault" in the semiconductor production process is decreased by this treatment.

Title: Manufacture of semiconductor device
Inventor: KADOTA YASUO
IPC: H01L21/318
Filed: 1978-10-12
Abstract: PURPOSE: To provide semiconductor devices comprising a conductor layer, a PCVD.Si 3 N 4  film, and a wiring in which occurrence of inaccurate contact to the surface of the conductor exposed to the atmosphere where the PCVD.Si 3 N 4  film is plasma-etched is prevented by providing a conductive oxide film over the conductor surface prior to the plasma-etching.  
     CONSTITUTION: On top of a silicon substrate 1 is formed a silicon oxide film 2, which is overlaid with aluminum 3 by evaporation. The surface of aluminum 3 is subjected to the anodic oxidation treatment to be converted to an alumina film 4, which is then partly and selectively removed to form a metallic wiring of aluminum,  followed by growing a silicon nitride film 5 in accordance with the vapor growth process by plasma excitation. The silicon nitride film 5 is treated in a plasma of Freon to be selectively removed to form an opening 6, exposing the alumina film 4. The alumina film 4 is then removed out of the opening 6, resulting in exposing the aluminum layer 3. A wire 7 is bonded to the exposed aluminum layer 3. According to the above method, good contact can be produced between the wire 7 and the aluminum surface, since the aluminum surface as the electrode remains unexposed when the silicon nitride film is treated by the plasma etching.

IPC: G01B5/02
Filed: 1994-04-27
Abstract: PURPOSE:To measure the inner length, outer length, width, thickness, etc., easily with high accuracy using a single measuring apparatus. CONSTITUTION:Inner and outer measuring pieces 3, 2 are attached to a measuring shaft 1 and a groove 4 for sinking the inner measuring piece 3 is made on a reference plane 5.

Title: Apparatus and method for adjusting weft inserting in warp opening in-line arranging loom
Inventor: URUSU SHIYAIHA
IPC: B65H51/00
Filed: 1995-05-25
Abstract: PURPOSE: To provide a device and method for delivering a weft yarn to a weaving rotor of a series shed type loom capable of automatically correcting the interruption of its weaving process caused by a disorder in its weft yarn insertion. CONSTITUTION: This method for weft yarn insertion involves drawing a length of weft yarn 7 from a supplying unit 2 and delivering the weft yarn to the loom in synchronicity with the weaving cycle. The weft yarn-delivering device 4 following behind the weft yarn-storing device 4a, decides the delivering direction of the weft yarn 7. The inserted length of the weft yarn 7 is measured by the number of rotation of a conveyer roller 40. In the case of an interruption of the weft yarn between the spool of the supplying unit 2 and the weft yarn-delivering device 4, it is detected by using sensors 46, 46a. On detecting the interruption of the weft yarn, the conveyer 40 continues to convey the weft yarn 7 stored in the weft yarn-storing means 4a until the complete weft yarn insertion into the loom has taken place.  Then the weft yarn 7 is cut at the end part 10 of the weft yarn-insertion side 100a and the loom is stopped. The remaining weft yarn 7 in a weft yarn-preparing unit 6 is drawn back by the conveyer roller 40 and discharged into a waste container 55.
