  • Patent number: 12237024
    Abstract: A memory device and a programming method thereof are provided. The programming method includes the following steps. According to a step value, based on an incremental step pulse programming scheme, multiple programming operations are performed for a selected memory page. In a setting mode, multiple program verify operations are respectively performed corresponding to the programming operations to respectively generate multiple pass bit numbers. In the setting mode, a pass bit number difference value of two pass bit numbers corresponding to two programming operations is calculated. In the setting mode, an amount of the step value is adjusted according to the pass bit number difference value.

  • 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.
