  • Publication number: 20240111178
    Abstract: A contact lens comprises an optical zone and a peripheral zone. The optical zone is used for vision correction. The peripheral zone surrounds the optical zone. The optical zone and the peripheral zone jointly define a geometric center and a horizontal axis passing through the geometric center. Two stabilization zones symmetrically arranged relative to the geometric center are formed in the peripheral zone. These stabilization zones gradually thicken relative to a base curved surface of the peripheral zone.

  • Patent number: 11949015
    Abstract: A method includes following steps. A semiconductor fin is formed extending from a substrate. A gate structure is formed extending across the semiconductor fin. Recesses are etched in the semiconductor fin. Source/drain epitaxial structures are formed in the recesses in the semiconductor fin. Formation of each of the source/drain epitaxial structures comprises performing a first epitaxy growth process to form a bar-shaped epitaxial structure in one of the recesses, and performing a second epitaxy growth process to form a cladding epitaxial layer cladding on the bar-shaped epitaxial structure. The bar-shaped epitaxial structure has a lower phosphorous concentration than the cladding epitaxial layer.
