  • Publication number: 20240387679
    Abstract: A semiconductor device and method of manufacture are provided. In some embodiments a treatment process is utilized to treat a work function layer. The treatment prevents excessive oxidation of the work function layer during subsequent processing steps, such as application of a subsequent photoresist material, thereby allowing the work function layer to be thinner than otherwise.

  • Publication number: 20140209766
    Abstract: A retaining apparatus includes a first bracket, a second bracket, and an operation member. The first bracket includes two sidewalls. The second bracket includes two side plates slidably attached to the sidewalls, respectively. The operation member includes an operation portion, a mounting piece fixed to the second sidewall, and an engaging piece. A flange extends from one of the side plates of the second bracket. When the second bracket and the first bracket slide toward each other, the engaging piece abuts against a first end of the flange. The operation portion is pressed inward to release the engaging piece from the flange, and the second bracket is slid out relative to the first bracket until the engaging piece is restored to abut against a second end of the flange.

  • Patent number: 8369093
    Abstract: A mounting apparatus for mounting an expansion card to an electronic device includes a panel, a fixing bracket, and two locking members. The panel includes a rectangular plate and a frame. The fixing bracket is pivotably secured to the frame. The fixing bracket includes a contact portion and two pivot portions. The contact portion includes a first latching plate and a second latching plate. The first latching plate and the second latching plate cooperatively define a receiving space therebetween. Each of the two pivot portions includes a main plate, a stop plate, and a resilient portion. The two locking members are received in the two pivot portions. The top surface and a block plate of the expansion card are received in the receiving space.

  • Publication number: 20120161599
    Abstract: An anti-drop structure includes a rail assembly, a drag assembly, and two latching members. The rail assembly includes a pair of L-shaped sliding rails. Each L-shaped sliding rail includes a sidewall and a holding portion bent outwards from an end of the sidewall. One end of the sidewall defines a latching opening. The drag assembly is slidably positioned on the holding portions of the sliding rails and located between the sidewalls of the sliding rails. The drag assembly includes two opposite side plates. Each latching member is positioned on an inner surface of a corresponding one of the side plates, and includes a latching portion passing through a corresponding side plate. The latching portion is configured to slid into a corresponding latching opening to prevent the drag assembly from dropping out of the rail assembly.
