  • Publication number: 20210082766
    Abstract: In a manufacturing process of a three-dimensional structure device such as a GAA type FET or a nanosheet fork type FET having stacked channels in which channels having a shape of a wire or a sheet are stacked in a direction vertical to a substrate, a work function control metal is separately formed without expanding a space between FETs having different threshold voltages. Therefore, a first step S10 of performing anisotropic etching to open the mask material 23 until the work function control metal film 22 is exposed; a second step S11 of depositing a protective film 26; a third step S12 of performing anisotropic etching to remove the protective film while remaining the protective film deposited on sidewalls of the mask material opened in the first step; and a fourth step S13 of performing isotropic etching to selectively remove the mask material between the channels relative to the protective film and the work function control metal film are executed.

  • Publication number: 20200328099
    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.

  • Publication number: 20200249630
    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.
