Abstract: The invention disclose a pixel in an image sensor capable of detecting infrared light and associated fabrication method. The image sensor includes a semiconductor substrate has a first photodiode and a second photodiode adjacent to the first photodiode. A planarized dielectric layer having a recessed region is disposed on a first side of the semiconductor substrate. A first color filter disposed on the planarized dielectric layer aligned with the first photodiode and configured to transmit light of a first wavelength range. A second color filter disposed in the recessed region and on the planarized dielectric layer. The second color filter is aligned with the second photodiode, and configured to transmit light of a second wavelength range that is different from the first wavelength range. A first depth-wise thickness of the first color filter is less than a second depth-wise thickness of the second color filter.

Abstract: A wafer including a substrate, a dielectric layer over the substrate, and a conductive layer over the dielectric layer is disclosed. The substrate has a main portion. A periphery of the dielectric layer and the periphery of the main portion of the substrate are separated by a first distance. A periphery of the conductive layer and the periphery of the main portion of the substrate are separated by a second distance. The second distance ranges from about a value that is 0.5% of a diameter of the substrate less than the first distance to about a value that is 0.5% of the diameter greater than the first distance.

Abstract: A phase change memory and a method of manufacture are provided. The phase change memory includes a layer of phase change material treated to increase the hydrophobic nature of the phase change material. The hydrophobic nature of the phase change material improves adhesion between the phase change material and an overlying mask layer. The phase change material may be treated, for example, with a plasma comprising N2, NH3, Ar, He, O2, H2, or the like.

Abstract: A phase change optical recording medium. A recording layer is formed on a substrate having a plurality of non-metal particles disposed therein uniformly. Consequently, phase change can occur not only in the interface between crystal and amorphous regions, but also the interface between the particles and the amorphous region.
