Patent JP-H0228322-A (JP)
Title: Preliminary treatment of semiconductor substrate
Inventor: ITO HIROMI
IPC: H01L21/302
Filed: 1988-10-24
Abstract: PURPOSE:To remove a natural oxidation film or contaminant applying on the surface of a semiconductor substrate by a method wherein the surface of the semiconductor substrate is irradiated with light having wavelength by which photochemical reaction occurs with the natural oxidation film or contaminant which has applied on the substrate surface under specific conditions when the semiconductor substrate is heated. CONSTITUTION:A silicon substrate 4 mounted on a substrate table 5 has undergone solution treatment: it carries a natural oxidation film in exposure to air. By feeding HCl gas into a chamber 3, supplying the HCl gas to the surface of the silicon substrate 4 and lighting low pressure mercury lamp 1, ultraviolet rays fall on the surface of the silicon substrate 4 through an ultraviolet rays injection window 2. At the same time with this irradiation with ultraviolet rays, the silicon substrate 4 is heated to 200 to 700 deg.C. This facilitates reaction between reaction gas and the natural oxidation film due to synergistic effect of light and heat so that the natural oxidation film can be removed with reaction gas which cannot be activated only by light.

IPC: B65H37/04
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To apply a paste to a predetermined position correctly on a surface particularly near a spine of an internal book being bound, by providing a paste supplying device for attaching a liquid paste to peripheral faces of roller flanges which come in contact with a paper product during conveyance and a scraper device for adjusting the position and length of the paste attached to the peripheral faces of the roller flanges. SOLUTION: When an internal book pasting device 10 is started, a large number of internal books H are sent with their spines downward on a conveying passage S at predetermined intervals. To a pair of rotary bodies 18 and 19, a paste is attached while peripheral faces of roller flanges 20 and 21 are passing a paste reservoir. A sensor detects a position of each of the moving internal books H and calculates a position of the peripheral face where the top side of the internal book H begins to come into contact with the peripheral faces of the roller flanges 20 and 21. By scraping the paste on the peripheral face by a length of H1 from the contact point, a non- attaching part is formed.  For making a state that the paste is attached on the peripheral face by a length of H3, each of scraper devices 23 and 24 is operated in synchronization with the conveyance of the internal book H so as to attach the paste to a predetermined position correctly.

Abstract: PROBLEM TO BE SOLVED: To shorten the time needed for processing and calculate timing characteristics with high precision by returning to a waveform determination step and repeatedly calculating the characteristics value of a waveform until necessary precision is obtained, and outputting the characteristic value. SOLUTION: In addition to information needed for a circuit simulation step, e.g. circuit connection information and input information on an input waveform, etc., a result analytic indication needed for a result analytic step, necessary convergence conditions, etc., are inputted. An input waveform to be used next is determined according to the inputted information. Then an input waveform is generated and an input disk is generated. The circuit simulation of this input disk is performed, only information needed to calculate characteristics is extracted, and the circuit simulation result is analyzed. When the analytic result do not meet convergence conditions, the same process is repeated until the convergence conditions are satisfied. When the convergence conditions are satisfied, a timing characteristic value is outputted.  In this case, input waveforms (b)-(d) are generated in addition to the initial value (a) of the input waveform and the final value (e) of the input waveform.
