    Abstract: An apparatus and a method for configuring or updating a programmable logic device are provided. The apparatus includes a control module and a storage module connected to the control module. The control module includes: a JTAG interface for connecting the control module to a JTAG host, and a configuration interface compatible with a to-be-configured programmable logic device. The control module is configured to: after receiving a first control instruction including configuration information via the JTAG interface, store the configuration information into the storage module; and after receiving a configuration instruction, read the configuration information to configure the to-be-configured programmable logic device. A configuration clock used in a process that the control module configures the to-be-configured programmable logic device is generated from the to-be-configured programmable logic device, the control module or an external clock source.

    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.

    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.
