  • Publication number: 20200018896
    Abstract: An anti-cracking panda-type polarization-maintaining optical fiber includes a cladding layer, stress layers, and a fiber core. The fiber core is located in the center of the cladding layer. The stress layers are located symmetrically at two sides of the fiber core with a distance away from the fiber core and are located within the cladding layer. Each stress layer is enclosed at edges of their outer sides by a transition layer with a gradient refractive index. By providing the transition layer with the gradient refractive index at the edge of the outer side of the stress layer, the pressure stress at the edge of the stress layer is decomposed and released, so as to avoid cracks at the edge of the polished stress layer on the end of the optical fiber, and thus optimizes the performance of the polarization-maintaining optical fiber by decreasing the room temperature polishing cracking rate.

    Abstract: The present disclosure relates to a method of forming a transistor device. In this method, first and second well regions are formed within a semiconductor substrate. The first and second well regions have first and second etch rates, respectively, which are different from one another. Dopants are selectively implanted into the first well region to alter the first etch rate to make the first etch rate substantially equal to the second etch rate. The first, selectively implanted well region and the second well region are etched to form channel recesses having equal recess depths. An epitaxial growth process is performed to form one or more epitaxial layers within the channel recesses.

According to the disclosed embodiments, the imaging system comprises one or more cameras configured to capture the same scene within each camera's field of view. The imaging system also includes a plurality of bandpass filters that may be positioned in front of one or more cameras. Each bandpass filter may allow the transmission of incident electromagnetic signals between different pairs of first and second wavelengths. Accordingly, when the bandpass filters are positioned in front of the one or more cameras, each camera captures a different spectral image, i.e., containing only certain frequency components of the same scene being imaged in the cameras. The bandpass filters may be selectively aligned with one or more cameras by rotating and/or translating the filters relative to the cameras' positions in the imaging system.

    Abstract: FinFET patterning methods are disclosed for achieving fin width uniformity. An exemplary method includes forming a mandrel layer over a substrate. A first cut removes a portion of the mandrel layer, leaving a mandrel feature disposed directly adjacent to a dummy mandrel feature. The substrate is etched using the mandrel feature and the dummy mandrel feature as an etch mask, forming a dummy fin feature and an active fin feature separated by a first spacing along a first direction. A second cut removes a portion of the dummy fin feature and a portion of the active fin feature, forming dummy fins separated by a second spacing and active fins separated by the second spacing. The second spacing is along a second direction substantially perpendicular to the first direction. A third cut removes the dummy fins, forming fin openings, which are filled with a dielectric material to form dielectric fins.
