  • Patent number: 11114339
    Abstract: A method of manufacturing a device includes exposing at least one of a source/drain contact plug or a gate contact plug to a metal ion source solution during a manufacturing process, wherein a constituent metal of a metal ion in the metal ion source solution and the at least one source/drain contact plug or gate contact plug is the same. If the source/drain contact plug or the gate contact plug is formed of cobalt, the metal ion source solution includes a cobalt ion source solution. If the source/drain contact plug or the gate contact plug is formed of tungsten, the metal ion source solution includes a tungsten ion source solution.

  • Publication number: 20170160628
    Abstract: A light source module including a light source and a light diffusion and filtering plate is provided. The light source is configured to provide an illumination light beam. The light diffusion and filtering plate is disposed on a transmission path of the illumination light beam. The light diffusion and filtering plate includes a light-transparent substrate, a light diffusion structure, and a light filtering structure. The light-transparent substrate has a first surface facing to the light source and a second surface opposite to the first surface. The light diffusion structure is disposed on the first surface, and the light filtering structure is disposed on the second surface. The light source module may reduce flicker. Further, a projection apparatus having the light source module is also provided.
