  • Patent number: 10157956
    Abstract: A method for monolithic integration of a hyperspectral image sensor is provided, which includes: forming a bottom reflecting layer on a surface of the photosensitive region of a CMOS image sensor wafer; forming a transparent cavity layer composed of N step structures on the bottom reflecting layer through area selective atomic layer deposition processes, where N=2m, m?1 and m is a positive integer; and forming a top reflecting layer on the transparent cavity layer. With the method, non-uniformity accumulation due to etching processes in conventional technology is minimized, and the cavity layer can be made of materials which cannot be etched. Mosaic cavity layers having such repeated structures with different heights can be formed by extending one-dimensional ASALD, such as extending in another dimension and forming repeated regions, which can be applied to snapshot hyperspectral image sensors, for example, pixels, and greatly improving performance thereof.

  • Patent number: 9911617
    Abstract: The invention discloses a novel dry etching method, which comprises the following steps: forming a to-be-etched layer on a semiconductor substrate; forming a masking material on the to-be-etched layer; carrying out dry etching on the masking material and the to-be-etched layer; simultaneously carrying out lateral etching (parallel to the surface of the substrate) of a masking layer and longitudinal etching (vertical to the surface of the substrate) of the to-be-etched layer; and obtaining the inclination angle (the included angle between a slope surface and the surface of the substrate) of the corresponding etched slope surface by accurately controlling the speed ratio. The method can flexibly adjust the inclination angle of the etched slope surface within a large range (0-90 degrees), and especially has advantages in the field of the application with a small inclination angle (smaller than 20 degrees) of the etched slope surface in comparison with a conventional etching method.

  • Patent number: 8252689
    Abstract: The present invention provides a chemical-mechanical planarization method. The chemical-mechanical planarization method includes: providing a substrate including a gate and source/drain regions on the sides of the gate, the gate and the source/drain regions being overlay by an insulating layer, and the insulating layer including a protruding part above the gate and a recessed part above a surface of the substrate between gates; selectively doping the insulating layer such that only the protruding part is doped; and performing CMP on the substrate after doping, to remove the protruding part and planarize the surface of the substrate. By selectively doping the insulating layer, the method makes only the protruding part of the insulating layer doped, enhancing the corrosive attacks on the material of the protruding part by the slurry in the CMP, and increasing the removal rate of the material of the protruding part by the CMP.
