    Abstract: An image sensing device that can adjust parameters of an image before sending it to a processor for reducing computing power and/or storage requirement is disclosed. The image sensing device includes an array of sensing pixels; an output amplifier; an analog-to-digital converter; a first set of registers and a second set of registers; an activation circuit; and a profiling logic. The profiling logic conducts statistical analysis on output data and adjusts parameters stored in the first set of registers until results of the statistical analysis reaches a target standard, wherein the adjusted parameters are used to generate an output image by each sensing pixel of the array of sensing pixels once the target standard is reached and a notification signal is sent to an external device for notifying the failure of parameter adjustment if the target standard fails to be reached within a predetermined times of adjustment.

    Abstract: A silicon wafer having colored top side is disclosed in the present invention. The silicon wafer includes: a wafer; a first semi-conductor layer, formed on at least a portion of a top side of the wafer, having periodical structures to form a grating pattern, and a second semi-conductor layer, formed on the first semi-conductor layer with a bottom side substantially fully contacted with the periodical structures. The first semi-conductor layer and the second semi-conductor layer form a photonic crystal layer and work to reflect a predetermined wavelength range of incident visible light beams. The present invention provides a silicon wafer which can reflect specified color(s) from the surface facing external light beams. Therefore, dies from cutting the silicon wafer with functions to interact with external environment rather than packaged can have advantages to show some specified logo or trademark.

    Abstract: A capacitive image sensor and a method for running the capacitive image sensor are disclosed. The capacitive image sensor includes a number of capacitive sensing elements, forming an array, each capacitive sensing element for transforming a distance between a portion of a surface of an approaching finger and a top surface thereof into an output voltage, wherein a value of the output voltage is changed by a driving signal exerted on the finger; an A/D converter, for converting the output voltage into a number and outputting the number; and a signal source, for providing the driving signal to the finger.

    Abstract: A method for enhancing surface characteristics of a fingerprint sensor and a protective structure made according to the method are disclosed. The method includes the steps of: providing a fingerprint sensor having a number of detecting elements beneath a top surface of the fingerprint sensor, the detecting element is used to detect changes of capacitance over a portion of a finger; forming a metal mesh layer over the top surface of the fingerprint sensor, wherein metal lines of the metal mesh layer are formed periodically and each of them is located between two adjacent detecting elements; forming a passivation layer on the metal mesh layer to shape a concave-convex top surface; and filling concave portions of the passivation layer with a Diamond-Like Carbon (DLC) material. A convex portion of the passivation layer is substantially above the metal line of the metal mesh layer.
