    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 portable fingerprint device is disclosed. The device includes an image sensing unit for capturing fingerprint images of a finger; a microprocessor, linked to the image sensing unit, for recording the fingerprint images of the finger, identifying the fingerprint images of the finger from a fingerprint database, receiving a command signal and transmitting a response signal; and a communication unit, connected to the microprocessor, for exchanging the command signal and the response signal between the microprocessor and a command device separated from the portable fingerprint device. The portable fingerprint device not only can identify fingerprints, but also can detect a sequence of finger motion, or “signature”, and use such information as part of the identification/authentication process.
