Abstract: A method for photo-detecting and an apparatus for the same are provided. The apparatus for photo-detecting includes a first P-N diode and a second P-N diode. The first P-N diode, has a first P-N junction which has a first thickness, by which a first electrical signal is generated when irradiated by light, and the second P-N diode has a second P-N junction which has a second thickness, by which a second electrical signal is generated when irradiated by light. The second thickness is larger than the first thickness and an operation of the first electrical signal and the second electrical signal is proceeded for obtaining a third electrical signal.

Abstract: A flash memory cell includes a substrate and a gate structure formed on the substrate. The gate structure includes a tunneling layer over the substrate, a storage layer over the tunneling layer, a blocking layer over the storage layer, and a gate electrode over the dielectric. The storage layer preferably has a conduction band lower than a conduction band of silicon. The blocking layer is preferably formed of a high-k dielectric material.

Abstract: A stackable heat sink comprising a plurality numbers of metal heat dissipation plates, the heat dissipation plate further comprises a bottom plate, two side plates facing each other locates on both sides of the bottom plate, a bending area is bent from the top of the side plate, two standing plates stretches up from the bending area and facing another standing plate, two fastening plates each is formed on the proper location on the standing plate, the fastening plate is bendable and forms a bending line with the standing plate; two fastening crevices each is located on the junction of the bottom plate and the side plate.
