  • Patent number: 11521971
    Abstract: A first dielectric layer is formed over upper and side surfaces of a semiconductor fin structure. A mask layer is formed over a first portion of the first dielectric layer disposed over the upper surface of the fin structure. The mask layer and the first dielectric layer have different material compositions. Second portions of the first dielectric layer disposed on side surfaces of the fin structure are etched. The mask layer protects the first portion of the first dielectric layer from being etched. A second dielectric layer is formed over the mask layer and the side surfaces of the fin structure. An oxidation process is performed to convert the mask layer into a dielectric material having substantially a same material composition as the first or second dielectric layer. The dielectric material and remaining portions of the first or second dielectric layer collectively serve as a gate dielectric of a transistor.

  • Publication number: 20220371168
    Abstract: An air-path structure of pneumatic a nail gun, formed inside a gun body containing high-pressure air, comprises a main air chamber, a firing valve air chamber and a time-delayed air chamber that continuously releases the high-pressure air to the atmosphere. The gun body is configured with a trigger valve and a slider valve. The inside of the trigger valve is formed with a safety-on air chamber and a safety-off air chamber. The trigger valve controls the high-pressure air inside the firing valve air chamber to be discharged to the atmosphere. The slider valve controls the high-pressure air inside the main air chamber flowing toward the firing valve air chamber, the time-delayed air chamber and the safety-off air chamber. Specifically, the safety-on air chamber is constantly communicated with the main air chamber and constantly contains high-pressure air, and the slider valve can control the high-pressure air inside the safety-off air chamber flowing into the time-delayed air chamber.

  • Patent number: 11481380
    Abstract: Scanning and rescanning detect state inconsistencies between data entities in repositories or other components of a distributed computing environment. First, entities are scanned based on a cutoff time TO. Entities for which state comparison is undesired are placed in a skipped entity list. Any inconsistencies found in other entities is reported. Then subsequent rescanning fetches state and attempts to pare down the skipped entity list. Rescanning may be capped. Inconsistencies may be detected without requiring downtime from services that update data entity state, and false reports of inconsistency may be avoided.

  • Publication number: 20220328654
    Abstract: A dummy fin described herein includes a low dielectric constant (low-k or LK) material outer shell. A leakage path that would otherwise occur due to a void being formed in the low-k material outer shell is filled with a high dielectric constant (high-k or HK) material inner core. This increases the effectiveness of the dummy fin to provide electrical isolation and increases device performance of a semiconductor device in which the dummy fin is included. Moreover, the dummy fin described herein may not suffer from bending issues experienced in other types of dummy fins, which may otherwise cause high-k induced alternating current (AC) performance degradation. The processes for forming the dummy fins described herein are compatible with other fin field effect transistor (finFET) formation processes and are be easily integrated to minimize and/or prevent polishing issues, etch back issues, and/or other types of semiconductor processing issues.
