  • GATE STRUCTURE IN SEMICONDUCTOR METHOD AND METHOD OF FORMING THE SAME
    Publication number: 20250063778
    Abstract: A method includes removing a first dummy gate stack and a second dummy gate stack to form a first trench and a second trench. The first dummy gate stack and the second dummy gate stack are in a first device region and a second device region, respectively. The method further includes depositing a first gate dielectric layer and a second gate dielectric layer extending into the first trench and the second trench, respectively, forming a fluorine-containing layer comprising a first portion over the first gate dielectric layer, and a second portion over the second gate dielectric layer, removing the second portion, performing an annealing process to diffuse fluorine in the first portion into the first gate dielectric layer, and at a time after the annealing process, forming a first work-function layer and a second work-function layer over the first gate dielectric layer and the second gate dielectric layer, respectively.

  • SAND-PROOF SPRINKLER MECHANISM
    Publication number: 20250033067
    Abstract: A sand-proof sprinkler mechanism has a base. A housing and a connecting platform are provided on the base. A hose is rotatably connected between the housing and the connecting platform. The housing has a water outlet, a housing inner chamber and a water inlet that are in communication with the hose. The housing includes an impeller transmission member and a transmission device that is drivingly connected to the impeller transmission member and the hose. The housing further has a sealing chamber for mounting the transmission device. A water baffle is provided at an opening of the sealing chamber for covering the sealing chamber. The above structure prevents particles from entering and getting stuck.
