  • Patent number: 10916421
    Abstract: A method for manufacturing an epitaxial silicon wafer enables to lower carbon concentration in an epitaxial film. The method forming an epitaxial silicon wafer where an epitaxial film is formed on a silicon wafer in a reaction chamber including a wafer-holding susceptor that separates an upper and lower space communicating through a predetermined gap includes steps of forming a flow of a processing gas flowing laterally along an upper surface of the wafer in the upper space and a flow of a main purging gas flowing towards the susceptor upwardly in the lower space being formed simultaneously, setting a flow rate ratio of the main purging gas flow rate to the processing gas flow rate to be 1.0/100 to 1.5/100 where the processing gas flow rate is set as 100, and controlling a pressure in the upper space to be within an atmospheric pressure ±0.2 kPa at least.

  • Patent number: 10429714
    Abstract: A driver for an electrochromic element is configured to adjust the transmittance of a solution-type electrochromic element to allow the element to display a tone. The element has a pair of electrodes and at least one organic electrochromic material mixed between the electrodes. The driver has an adjusting controller configured to adjust the transmittance of the element. The adjusting controller has controller A and controller B. Controller A is configured to saturate a change in the transmittance of the element to an initial state by applying the voltage which resets the element to the initial state. Controller B is configured to control the tone of the element by applying the voltage which adjusts the transmittance of the element following controller A.
