  • Publication number: 20240096705
    Abstract: A semiconductor device includes a plurality of channel layers vertically separated from one another. The semiconductor device also includes an active gate structure comprising a lower portion and an upper portion. The lower portion wraps around each of the plurality of channel layers. The semiconductor device further includes a gate spacer extending along a sidewall of the upper portion of the active gate structure. The gate spacer has a bottom surface. Moreover, a dummy gate dielectric layer is disposed between the gate spacer and a topmost channel layer of plurality of channel layers. The dummy gate dielectric layer is in contact with a top surface of the topmost channel layer, the bottom surface of the gate spacer, and the sidewall of the gate structure.

  • Publication number: 20080155291
    Abstract: A method for resetting a micro controller is disclosed. The method uses an improved micro controller reset circuit designed for loading micro controller options regardless of whether a reset key is pressed after the power is turned on. In this method, the initial values of the micro controller are recovered so as to reduce power consumption and avoid conflict between signals.
