  • Method of removing material layer and remnant metal
    Patent number: 7884028
    Abstract: A method of removing material layer is disclosed. First, a semiconductor substrate is fixed on a rotating platform, where a remnant material layer is included on the surface of the semiconductor substrate. Afterward, an etching process is carried out. In the etching process, the rotating platform is rotated, and an etching solution is sprayed from a center region and a side region of the rotating platform toward the semiconductor substrate until the material layer is removed. Since the semiconductor substrate is etched by the etching solution sprayed from both the center region and the side region of the rotating platform, the etching uniformity of the semiconductor substrate is improved.

  • CURRENT COLLECTING POST SEAL FOR HIGH DURABILITY LITHIUM-ION CELLS
    Publication number: 20100273046
    Abstract: A cover assembly for a Lithium-ion battery container to improve the durability of the battery. A high pressure injection molded polymer is combined with flanges disposed on the current collecting posts of the battery to provide an improved seal for the battery cover, especially at the interface of the cover and the current collecting posts. The injection molded polymer is fused to the flanges, current collecting posts and container cover to result in a diffusion path of increased length for gases and/or liquids which are known to enter or escape from battery containers. Additional polymer layers can be applied to the assembly to further improve the seal.
