  • Publication number: 20250169089
    Abstract: A method of manufacturing step of a device having a gate and a silicon substrate that are insulation-isolated from each other. In the method, germanium compositions of a silicon germanium sacrificial layer for forming a stacked channel and a germanium composition of a silicon germanium sacrificial layer for insulation-isolating the gate and the substrate are not changed. After the stacked film is etched, a protective dielectric film is formed on a sidewall of the stacked film, which is repeated using different protective film materials. Thereafter, a silicon sacrificial layer and a silicon germanium sacrificial layer remaining in a lower portion are removed by isotropic etching to form a region in which the insulating isolation film is embedded. The steps from the formation of the stacked film of the protective dielectric films to the removal of the sacrificial layer by etching in the continuous process use the same apparatus.

  • Patent number: 11915951
    Abstract: A plasma processing apparatus includes a stage disposed in a processing chamber for mounting a wafer, a plasma generation chamber disposed above the processing chamber for plasma generation using process gas, a plate member having multiple introduction holes, made of a dielectric material, disposed above the stage and between the processing chamber and the plasma generation chamber, and a lamp disposed around the plate member for heating the wafer. The plasma processing apparatus further includes an external IR light source, an emission fiber arranged in the stage, that outputs IR light from the external IR light source toward a wafer bottom, and a light collection fiber for collecting IR light from the wafer. Data obtained using only IR light from the lamp is subtracted from data obtained also using IR light from the external IR light source during heating of the wafer. Thus, a wafer temperature is determined.

  • Patent number: 11016446
    Abstract: A timepiece includes a stepping motor having a rotor and a coil, and a drive circuit that applies a first drive pulse having a stable stationary position at a rotor rotation angle of 90 degrees or less from a reference position and a second drive pulse having the stable stationary position at a rotor rotation angle of 90 degrees or more from the reference position, as a pulse for driving the rotor, to the coil. When a period during which the pulse is not applied to the coil is assumed as a waiting period, the drive circuit generates the waiting period after a first application of the second drive pulse after an application of the pulse to the coil is started and rotates the rotor by one or more turns without passing through the waiting period at at least one predetermined timing after the waiting period.
