  • Publication number: 20250072119
    Abstract: A semiconductor device, includes a first metal layer, a second metal layer, and at least one conductive via. The first metal layer has a first conductor that extends in a first direction and a second conductor that extends in the first direction. The second metal layer has a third conductor that extends in a second direction, wherein the second direction is transverse to the first direction. The at least one conductive via connects the first conductor and the second conductor through the third conductor. The semiconductor device further includes at least one of a first gate electrode that extends in the second direction and is connected to the first conductor, or a drain/source contact that extends in the second direction and is connected to the second conductor.

  • Publication number: 20250063809
    Abstract: The present disclosure describes a structure including a fin field effect transistor (finFET) and a nano-sheet transistor on a substrate and a method of forming the structure. The method can include forming first and second vertical structures over a substrate, where each of the first and the second vertical structures can include a buffer region and a first channel layer formed over the buffer region. The method can further include disposing a masking layer over the first channel layer of the first and second vertical structures, removing a portion of the first vertical structure to form a first recess, forming a second channel layer in the first recess, forming a second recess in the second channel layer, and disposing an insulating layer in the second recess.

  • Patent number: 12216281
    Abstract: The present specification describes examples of position-based switching of display devices. An example augmented reality (AR) device includes an AR display device to render display data. The example AR device also includes a wireless communication device to transmit and receive wireless signals. The example AR device further includes a processor to: 1) determine a position of the AR device relative to a computing device based on wireless signals communicated with the computing device; and 2) switch an activity state of the AR display device based on the determined position of the AR device relative to the computing device.

  • Patent number: 8923001
    Abstract: An electronic device includes a housing, a chip card received in the housing, and a chip card protecting cover assembly. The chip card protecting cover assembly includes a housing, a first magnet and a second magnet. The magnetic force between the first magnet and the second magnet drives the protecting cover to rotate relative to the housing, thereby covering or exposing the chip card.
