  • Patent number: 11612074
    Abstract: A waterproofing structure is disposed between a first assembling component and a second assembling component of an electronic device. The second assembling component is detachably installed on the first assembling component. The waterproofing structure includes a sealing component, an abutting component and a sliding component. The sealing component is located between the first assembling component and the second assembling component. The abutting component is fixed on the second assembling component. The sliding component is slidably installed on the first assembling component. When the sliding component slides along a first direction, the sliding component forces the abutting component to drive the second assembling component to move toward the first assembling component, so that the sealing component is pressed by the first assembling component and the second assembling component.

  • Publication number: 20220310451
    Abstract: A method includes forming isolation regions extending into a semiconductor substrate, and recessing the isolation regions. After the recessing, a portion of a semiconductor material between the isolation region protrudes higher than top surfaces of the isolation regions to form a semiconductor fin. The method further includes forming a gate stack, which includes forming a gate dielectric on sidewalls and a top surface of the semiconductor fin, and depositing a titanium nitride layer over the gate dielectric as a work-function layer. The titanium nitride layer is deposited at a temperature in a range between about 300° C. and about 400° C. A source region and a drain region are formed on opposing sides of the gate stack.
