  • Patent number: 11264287
    Abstract: An anchored cut-metal gate (CMG) plug, a semiconductor device including the anchored CMG plug and methods of forming the semiconductor device are disclosed herein. The method includes performing a series of etching processes to form a trench through a metal gate electrode, through an isolation region, and into a semiconductor substrate. The trench cuts-through and separates the metal gate electrode into a first metal gate and a second metal gate and forms a recess in the semiconductor substrate. Once the trench has been formed, a dielectric plug material is deposited into the trench to form a CMG plug that is anchored within the recess of the semiconductor substrate and separates the first and second metal gates. As such, the anchored CMG plug provides high levels of resistance to reduce leakage current within the semiconductor device during operation and allowing for improved V-trigger performance of the semiconductor device.

  • Publication number: 20220035433
    Abstract: Systems, apparatuses, and methods for saving power on a bus interface are described. A system includes a host, a device, and a repeater interposed between the host and the device. While the host and device are in a low-power state, the repeater monitors a first bus to determine if the device has woken up. When the repeater detects a remote wake-up event initiated by the device, the repeater generates an interrupt which is sent to the host. The host responds to the interrupt by initiating a resume wake-up event procedure that assumes the device is still asleep. In this way, the host is able to stay in the low-power state longer while also using a wake-up procedure that does not require the host to be aware of the existence of the repeater.

    Abstract: An information display board with improved display performance by light-extending light sources is revealed. The information display board includes a display board and a plurality of light-extending light sources each of which consists of a light emitting diode (LED) and a reflective panel. The LED has a light emitting side and a backside while the reflective panel is disposed on the light emitting side of the LED for reflecting a part of light emitted from the light emitting side to the display board on the backside to form an expanded area. Thus illuminance and illuminated area of information shown on the display board are increased. By continuous lighting generated, messages/information shown on the information display board such as traffic sign can be read more clearly and comfortably.

    Abstract: The panoramic augmented reality system includes a panoramic camera device data-linked with a networked storage storing a panoramic image captured by panoramic camera device. The networked storage is connected by at least an electronic device which includes an APP, an AR module, and at least an image adjustment module. To produce live streaming, the panoramic camera device is set up in the scene and the panoramic image captured by the panoramic camera device is stored in the networked storage. The panoramic image is then accessed through the APP and a 3D space is created together with the AR module. A display image corresponding to the user's position and direction in the 3D space is created and continuously updated based on the image adjustment module's detection. Therefore, the user may navigate the 3D space as if he/she is actually present in the scene, creating a realistic experience.
