  • Patent number: 10276449
    Abstract: A method for forming a semiconductor device structure includes providing a substrate having a first fin structure and a second fin structure that are capped by a patterned hard mask structure. A liner layer and an overlying insulating layer are formed between the first and second fin structures. A multi-step etching process including a first step of selectively removing the patterned hard mask structure and a second step of in-situ and selectively removing a portion of the insulating layer to form an isolation feature is performed. The process gas used in the multi-step etching process includes a first etching gas and a second etching gas. The flow rate of the first etching gas is greater than that of the second etching gas in the first step and the flow rate of the first etching gas is less than that of the second etching gas in the second step.

  • Publication number: 20190067088
    Abstract: An opening is formed within a dielectric material overlying a semiconductor substrate. The opening may comprise a via portion and a trench portion. During the manufacturing process a treatment chemical is placed into contact with the exposed surfaces in order to release charges that have built up on the surfaces. By releasing the charges, a surface change potential difference is reduced, helping to prevent galvanic corrosion from occurring during further manufacturing.

  • Patent number: 9804332
    Abstract: A multi-channel wavelength division multiplexing/demultiplexing device includes optical filters for respective optical channels, and at least one microlens. The optical filters guide a light beam to travel along a preset optical path, and each optical filter filters a specific and different range of wavelength, and has a first surface for incident and reflective light, and a second surface for outgoing light through penetration as an output beam for the corresponding channel. Each microlens is installed between two adjacent optical filters to adjust optical beam shape of the traveling light along the optical path, particularly, altering a beam waist of a Gaussian beam and an imaging position to greatly increase optical efficiency of collimators for the whole system.

  • Patent number: 9661938
    Abstract: A foldable frame assembly for a playpen includes a collapsible bottom frame which has a central support mount, a plurality of linking elements, a plurality of first linking rods and a plurality of second linking rods. The linking elements are pivoted between the central support mount and the lower end of the plurality of pillars respectively. Each of the linking elements is provided with a sliding part for moving along the linking elements. When the central support mount was lifted upward, the second linking rods are associated with the first linking rods through the sliding parts thereby incurring an inward torque to prevent the pillars from deflecting outward. By such of the inward torque, users can save their troublesome of stretching hands to hold and keep the pillars uprightly while converting the playpen into its folded configuration.
