Abstract: The present disclosure describes a semiconductor device with a nitrided capping layer and methods for forming the same. One method includes forming a first conductive structure in a first dielectric layer on a substrate, depositing a second dielectric layer on the first conductive structure and the first dielectric layer, and forming an opening in the second dielectric layer to expose the first conductive structure and a portion of the first dielectric layer. The method further includes forming a nitrided layer on a top portion of the first conductive structure, a top portion of the portion of the first dielectric layer, sidewalls of the opening, and a top portion of the second dielectric layer, and forming a second conductive structure in the opening, where the second conductive structure is in contact with the nitrided layer.

Abstract: A nail press structure of a nail ejection gun includes a frame body having a nail outlet seat, and a nail magazine. The nail magazine includes an L-shaped magazine plate assembled with a magazine seat, such that a plurality of nails may be received in the space defined between the magazine seat and the magazine plate. The magazine seat is formed with a plurality of magazine grooves, and the magazine plate is formed with a hollow plate locked on the magazine seat. A plurality of elastic members are placed between the magazine seat and the magazine plate. A plurality of nail press members are respectively placed in the magazine grooves, located between the magazine seat and the elastic member, and are pressed by the elastic members.

Abstract: Disclosed is a vibration controlling construction of a quick-release member for a fastening element driving tool. The tool includes a central plate mounted on a top surface of a magazine of the tool. A detachable quick-release member is mounted on the top surface of the central plate. A trigger is pivotally mounted on the quick-release member and has a locking ring. At least one hook integrally protrudes from the central plate and extends over the quick-release member. A slot is formed on a face and a slope extending from a top edge of the slot. A controlling member is received in the slot of the hook. The controlling member includes a slant so configured to correspond to the slope of the hook to abut upon the slope.
