  • Publication number: 20240150192
    Abstract: A semiconductor device with different configurations of gate structures and a method of fabricating the same are disclosed. The method includes forming a fin structure on a substrate, forming a gate opening on the fin structure, forming a metallic oxide layer within the gate opening, forming a first dielectric layer on the metallic oxide layer, forming a second dielectric layer on the first dielectric layer, forming a work function metal (WFM) layer on the second dielectric layer, and forming a gate metal fill layer on the WFM layer. The forming the first dielectric layer includes depositing an oxide material with an oxygen areal density less than an oxygen areal density of the metallic oxide layer.

  • Patent number: 11947086
    Abstract: A six-piece optical image capturing system is disclosed. In order from an object side to an image side, the optical lens along the optical axis includes a first lens with refractive power; a second lens with refractive power; a third lens with refractive power; a fourth lens with refractive power; a fifth lens with refractive power, and a sixth lens with negative refractive power. The image-side surface and object-side surface of the sixth lens are aspheric, and at least one surface of the sixth lens has an inflection point. At least one among the first lens to the fifth lens has positive refractive power. The optical lens of the optical image capturing system can increase aperture value and improve the imagining quality for use in compact cameras.

  • Patent number: 5836565
    Abstract: A supporting device for a picture frame comprises a mount adapted to be securely attached to a picture frame back and a support piece. The mount has one or more pairs of opposite sides defined on a periphery thereof. The support piece is selectably received in a selected pair of holes in corresponding pair of opposite sides of the mount. Depending on which pair of holes is selected to receive the support piece, the support piece is adaptable to picture frames of different sizes.
