  • Publication number: 20240344280
    Abstract: A segmental precast composite-material composite-slab composite beam and a construction method thereof are provided, relating to the technical field of bridge design and construction. The segmental precast composite-material composite-slab composite beam mainly includes a segmental precast orthotropic composite top slab, a web, a bottom slab, and a wet joint between segments. The orthotropic composite top slab is composed of an orthotropic slab and an ultra-high-performance concrete layer (UHPC), and the interface connection of the orthotropic slab and the UHPC structural layer is achieved by a shear key. The UHPC structural layer is superposed with the orthotropic slab in segments in a precast plant to form a composite-slab composite beam segment to be entirely transported, hoisted and assembled, and the connection of the UHPC structural layers between the segments is achieved by casting a transverse wet joint in place.

  • Publication number: 20240164087
    Abstract: The method of forming the semiconductor structure includes the following steps. Bit line structures are formed on a substrate. A first liner is formed on the bit line structures. A second liner is formed on the first liner. A portion of the second liner is removed to expose a portion of the top surface of the first liner. A portion of the first liner is removed to form a space between each bit line structure and the second liner and form a remaining first liner. A sealing material is formed at the opening of the space to form an air gap between each bit line structure and the second liner.

  • Patent number: 10916417
    Abstract: A pre-processing method, a method for forming a metal silicide and a semiconductor processing apparatus are disclosed by the present invention. In the pre-processing method, a plasma etching process is performed on a semiconductor structure including a substrate. A first conductive portion and an isolation spacer covering a side surface of the first conductive portion are formed on a surface of an active area in the substrate. In the plasma etching process, a bias voltage applied to a surface of the semiconductor structure is adjusted by adjusting power outputs of two RF sources and is not lower than 150 V. In the metal silicide formation method, after a semiconductor structure including a first conductive portion and a second conductive portion is pre-processed in the manner as described above, a metal film is deposited thereon and annealed to result in the formation of the metal silicide.

  • Patent number: 9643020
    Abstract: Processes for manufacture and assembly of implantable medical devices are described. In particular, techniques are provided for nondestructive electrical isolation assessment of feedthrough assemblies of the implantable medical devices. The feedthrough assemblies may include an insulating structure, a plurality of terminal pins extending through the insulator and a ferrule having an inner lumen into which the insulating structure is disposed. One or more insulating seals may be disposed at the interface of the ferrule-to-insulating structure and/or the terminal pin-to-insulating structure. The electrical isolation assessments may be based on the dielectric properties of the components of the feedthrough assemblies, such as the insulating structure.
