  • Publication number: 20250113576
    Abstract: Embodiments of the present disclosure provide semiconductor device structures and methods of forming the same. The structure includes a source/drain region disposed over a substrate, a gate electrode layer disposed over the substrate, a first gate spacer disposed between the gate electrode layer and the source/drain region, and a dielectric spacer disposed between the gate electrode layer and the source/drain region. A first portion of the dielectric spacer is in contact with a first portion of the first gate spacer. The structure further includes a sacrificial layer disposed between a second portion of the first gate spacer and a second portion of the dielectric spacer.

  • Publication number: 20250081730
    Abstract: A display may include an array of pixels such as light-emitting diode pixels. The pixels may include multiple circuitry decks that each include one or more circuit components such as transistors, capacitors, and/or resistors. The circuitry decks may be vertically stacked. Each circuitry deck may include a planarization layer formed from a siloxane material that conforms to underlying components and provides a planar upper surface. In this way, circuitry components may be vertically stacked to mitigate the size of each pixel footprint. The circuitry components may include capacitors that include both a high-k dielectric layer and a low-k dielectric layer. The display pixel may include a via with a width of less than 1 micron.

  • Patent number: 12230681
    Abstract: A semiconductor device includes first nanostructures vertically separated from one another, a first gate structure wrapping around each of the first nanostructures, and second nanostructures vertically separated from one another. The semiconductor device also includes a second gate structure wrapping around the second nanostructures, a first drain/source structure coupled to a first end of the first nanostructures, a second drain/source structure coupled to both of a second end of the first nanostructures and a first end of the second nanostructures, and a third drain/source structure coupled to a second end of the second nanostructures. The first drain/source structure has a first doping type, the second and third drain/source structures have a second doping type, and the first doping type is opposite to the second doping type.

  • Publication number: 20130032032
    Abstract: A filter device for filtering dust from air includes a housing, a dust collecting module, a spraying module, and an exhaust. The housing defines an air inlet near a bottom of the housing and an air outlet near a top of the housing. The dust collecting module is installed in the housing between the air inlet and the air outlet. The spraying module is placed in the housing between the dust collecting module and the air outlet. The exhaust is connected to the housing for generating air pressure difference between near the air outlet and near the air inlet, thereby drawing and introducing air containing dust from the bottom of the housing toward the top of the housing via the air inlet.

  • Publication number: 20040090154
    Abstract: A parallelepiped lifting device mounted under a computer desk in a storage position is disclosed. Prior to using a computer, the device is activated by starting a motor in a clockwise rotation to lift an LCD of the computer from under the desk by means of a mechanism comprising chains, sprockets, and a bar. A lowering of the device into the desk is performed by starting the motor in a counterclockwise rotation by means of the same mechanism. The invention can save desk space for other purposes in the storage position.
