  • Patent number: 10523057
    Abstract: The present application provides a wireless charging module and a modularized sensing device therewith. A first charging unit is disposed around the inside of the wireless charging module for wirelessly charging a sensing module. Without introducing a transmission line as an electricity transmitting medium, the sensing module can be directly disposed inside and charged by the wireless charging module, which improves flexibility of implementation. Further, since the first charging unit is configured to surround the inside of the wireless charging module shaped as a bowl structure, the sensing module can be simply disposed into the bowl structure and wirelessly charged by the surrounding first charging units, which saves the inconvenience of setting the sensing module to a specific location or area for stable wireless charging and increases effective charging angles.

  • Publication number: 20190237485
    Abstract: Some embodiments of the present disclosure relate to a method of forming a transistor. The method includes forming a gate dielectric over a substrate and forming a gate over the gate dielectric. The gate includes polysilicon extending between a first outermost sidewall and a second outermost sidewall of the gate. A mask is formed over the gate. The mask exposes a first gate region extending to the first outermost sidewall and covers a second gate region extending between the first gate region and the second outermost sidewall.

  • Patent number: 10276596
    Abstract: Some embodiments of the present disclosure relate to deceasing off-state leakage current within a metal-oxide-semiconductor field-effect transistor (MOSFET). The MOSFET includes source and drain regions. The source and drain regions are separated by a channel region. A gate is arranged over the channel region. The gate has a first gate region adjacent to the source region and a second gate region adjacent to the drain region. The first gate region is selectively doped adjacent the source region. The second gate region is undoped or lightly-doped. The undoped or lightly-doped second gate region reduces the electric field between the gate and the drain region, and hence reduces a gate induced drain leakage (GIDL) current between the gate and drain region. The undoped or lightly-doped region of the gate can reduce the GIDL current within the MOSFET by about three orders of magnitude. Other embodiments are also disclosed.
