  • Patent number: 10184185
    Abstract: In a gas flow monitoring method using a MFC (a flow control device) for controlling a flow rate of process gas from a process gas supply source and supply the process gas to a predetermined process chamber, a start shut-off valve placed upstream of the MFC, and a pressure gauge placed between the start shut-off valve and the MFC, the start shut-off valve is closed and a drop of pressure on an upstream side of the MFC is measured by the pressure gauge to measure a flow rate of the MFC, thereafter, the start shut-off valve is opened to monitor the flow rate of the MFC. The MFC is switched from an ON state to an OFF state before the start shut-off valve is opened. The method enables in-line monitoring a low rate of process gas without affecting a semiconductor manufacturing process.

  • Patent number: 8871363
    Abstract: Provided is a resistor film comprising vanadium oxide as a main component, wherein metal-to-insulator transition is indicated in the vicinity of room temperature in temperature variations of electric resistance, there is no hysteresis in a resistance change in response to temperature variations or the temperature width is small at less than 1.5K even if there is hysteresis, and highly accurate measurement can be provided when used in a bolometer. Upon producing the resistor film comprising vanadium oxide as a main component by treating a coating film of an organovanadium compound via laser irradiation or the like, a crystalline phase and a noncrystalline (amorphous) phase are caused to coexist in the resistor film.
