  • Publication number: 20220140080
    Abstract: A method for fabricating p-type field effect transistor (FET) includes the steps of first providing a substrate, forming a pad layer on the substrate, forming a well in the substrate, performing an ion implantation process to implant germanium ions into the substrate to form a channel region, and then conducting an anneal process to divide the channel region into a top portion and a bottom portion. After removing the pad layer, a gate structure is formed on the substrate and a lightly doped drain (LDD) is formed adjacent to two sides of the gate structure.

  • Publication number: 20220084372
    Abstract: A doorbell system includes a power supply circuit, a smart module, a chime, a chime switch and a control module. The smart module provides a smart function. The chime switch is electrically connected between the control module, the smart module, and the power supply circuit. When the chime switch is turned on, the current flows through the chime under control of the control module. When the chime switch is turned off, the current cannot flow through the chime under control of the control module; consequently, the buzzing sound cannot be generated.

  • Publication number: 20210272816
    Abstract: To reduce a thickness variation of a spin-on coating (SOC) layer that is applied over a plurality of first and second trenches with different pattern densities as a bottom layer in a photoresist stack, a two-step thermal treatment process is performed on the SOC layer. A first thermal treatment step in the two-step thermal treatment process is conducted at a first temperature below a cross-linking temperature of the SOC layer to cause flow of the SOC layer, and a second thermal treatment step in the two-step thermal treatment process is conducted at a second temperature to cause cross-linking of the SOC layer.
