  • Patent number: 11374109
    Abstract: A method for fabricating gate structures includes providing a substrate, configured to have a first region and a second region. Dummy gate structures are formed on the substrate at the first and second regions, wherein each of the dummy gate structures has a first gate insulating layer on the substrate and a dummy gate on the first gate insulating layer. An inter-layer dielectric layer is formed over the dummy gate structures. The inter-layer dielectric layer is polished to expose all of the dummy gates. The dummy gates are removed. The first gate insulating layer at the second region is removed. A second gate insulating layer is formed on the substrate at the second region, wherein the first gate insulating layer is thicker than the second insulating layer. Metal gates are formed on the first and the second insulating layer.

  • Patent number: 10409748
    Abstract: A bridge device includes a first physical layer circuit, a first buffer memory, a DMA controller, and a processor. The first physical layer circuit is configured to connect to an upstream device. The first buffer memory is configured to store a first data and transfer data to the upstream device via the first physical layer circuit. The DMA controller is coupled to the first buffer memory and configured to access the first data in the first buffer memory to read and/or write a storage device correspondingly. The processor is coupled to the first buffer memory and the DMA controller. When the bridge device receives a clear feature command from the upstream device, the processor is configured to reset the first buffer memory and the DMA controller to stop the data transferring between the upstream device and the bridge device.
