  • Patent number: 11935894
    Abstract: An integrated circuit device includes a device layer having devices spaced in accordance with a predetermined device pitch, a first metal interconnection layer disposed above the device layer and coupled to the device layer, and a second metal interconnection layer disposed above the first metal interconnection layer and coupled to the first metal interconnection layer through a first via layer. The second metal interconnection layer has metal lines spaced in accordance with a predetermined metal line pitch, and a ratio of the predetermined metal line pitch to predetermined device pitch is less than 1.

  • Publication number: 20240090210
    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.
