Title: Method and device for cleaning substrate
Inventor: KUNIYASU HITOSHI
IPC: H01L21/304
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To enhance drying effect and to make it passable to supply solvent to a substrate by the adequate amount, by supplying the atomized solvent to the surface of the substrate when the substrate in dried in spin cleaning. SOLUTION: As the solvent, isopropyl alcohol(IPA) is used. A IPA-mist supply nozzle 30 is arranged at the central part of the surface of a semiconductor wafer 23, which is set at a wafer chuck 24. Then, after contaminant cleaning solvent is cleaned out by super-pure water, the semiconductor wafer 23 is dried. That is to say, the semiconductor wafer 23 is dried by dispersing the water droplet on the surface by rotating the semiconductor wafer 23 at a high speed. At the same time, IPA mist 31 is supplied to the surface of the semiconductor wafer 23 from the nozzle 30 of an IPA-mist supply device 27, and dispersing drying is accellerated. At this time, for the inert gas turning to the carrier gas, the low pressure and flow rate are set without decreasing the drying effect by thinning the IPA mist 31.

Title: Resist pattern forming method
Inventor: NAKAMURA HIROYUKI
IPC: H01L21/027
Filed: 1989-06-30
Abstract: PURPOSE:To improve the productivity at the time of superposition drawing of a wide pattern and a narrow pattern, by a method wherein many alignment marks are read at the time of forming the pattern of a lower layer requiring highly precise alignment, and the mark reading is restricted to a minimum at the time of forming an upper layer wherein precision is not required so much. CONSTITUTION:While alignment marks 22 are detected for all chips 21, electron beam for a narrow punched-out pattern of, e.g. 0.25mum width is projected, thereby drawing narrow patterns on a lower resist 7 and an upper resist 8. Next, while an alignment mark 23 of only the chip 21 on the right upper end of a block is detected, electron beam for a wide pattern of 0.7mum width is projected; the wide pattern is drawn only on the upper layer resist film 8, and a pattern 11 for forming a mushroom type gate is obtained; thus an Au mushroom type gate 13 having a gate length of 0.25mum, an upper width of 0.7mum, and a length of 200mum is formed. In the case of forming a wide punched-out pattern, the alignment mark 23 for each block is detected in this manner, thereby reducing the time necessary for alignment.

Title: Enrollment of noninteractive system in voice recognition
Inventor: SHERWOOD STEFAN
IPC: G10L15/06
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To provide a method for a computer to enroll a user of a voice recognition system. SOLUTION: In the method, the data, which include plural user/utterances and represent the user voices that approximately correspond to an enrollment text, are collected and acoustic contents of the data corresponding to a certain user/utterance are analyzed. Then, based on the analysis result, the computer discriminates whether the user/utterance matches with any portions of the enrollment text or not. If a matching is observed, the computer updates the acoustic model corresponding to the portion of the enrollment text using the acoustic contents of the user/utterance. The computer is made capable of discriminating whether the user/utterance matches with any parts of the enrollment text or not even though the user misses pronouncing a word in the enrollment text while repeatedly reading the words.

Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To efficiently mold a high quality metal soap block free from cracks and cavities by using a resin mold having an extremely simple structure and not requiring a complicated temperature control device. SOLUTION: The heat conductivity of a resin mold 11 is set to 0.2-3.8kcal/ m.hr. deg.C (preferably 0.7-3.5kcal/m.hr. deg.C). The heat conductivity of the resin mold is controlled by adjusting the compounding amount of good heat-conducting material powder (e.g. metal powder, carbon powder). The procedure for molding for metal soap block comprises preliminarily heating the resin mold 11 at a temperature (e.g. 140 deg.C) near to the melting point of the metal soap, thermally melting the metal soap at a temperature of (the melting point+10 deg.C) (e.g. 140 deg.C), press-charging the melted metal soap into the resin mold 11 at a pressure of 2-7kgf/cm<2> , and subsequently naturally, gradually and uniformly cooling the whole parts of the resin mold 11 from 140 deg.C to 30 deg.C.  Thus, the high quality metal soap blocks gradually cooled and sufficiently relaxed in thermal impacts (thermal stresses) in the respective sites of the molded products and free from cracks and cavities can efficiently be molded.
