摘要:
In one embodiment, a digital X-ray detector is provided with a plurality of pixel regions. Each pixel region includes a first photodiode having a first area and a second photodiode having a second area equal to or smaller than the first area. The digital X-ray detector also includes a shielding structure that overlies the first and second photodiodes of each pixel region with the shielding structure shielding proportionally less of the first photodiode than of the second photodiode to provide the first photodiode with a first sensitivity and the second photodiode with a second sensitivity lower than the first sensitivity.

An article with an etch resistant coating is disclosed. The article is a heating element, wafer carrier, or electrostatic chuck. The article has a base substrate made of a ceramic or other material, and further has one or more electrodes for resistance heating or electromagnetic chucking or both. The eth resistant coating has a plurality of regions made from materials having different electrical volume resistivities, such that the overall coating has a bulk resistivity that can be tailored by varying the relative size of each region.
摘要:
A heating apparatus for regulating/controlling the surface temperature of a substrate is provided. At least a thermal pyrolytic graphite (TPG) layer is embedded in the heater to diffuse the temperature difference of the various components in the heating apparatus and provide temporal and spatial control of the surface temperature of the substrate, for a relatively uniform substrate temperature with the difference between the maximum and minimum temperature points on the substrate of less than 10° C.
摘要:
A composite article comprises a substrate having at least a substrate surface and a graded-composition coating disposed on a substrate surface. The composition of the coating material varies substantially continuously across its thickness. The coating reduces the transmission rates of oxygen, water vapor, and other chemical species through the substrate such that the composite article can be used effectively as a diffusion barrier to protect chemically sensitive devices or materials. An organic light-emitting device incorporates such a composite article to provide an extended life thereto.

The present disclosure relates to a limited play optical storage media and a method for limiting access to data thereon. This storage media includes a first substrate; a reflective layer; a data storage layer disposed between said first substrate and said reflective layer; a reactive layer comprising at least one reactive material disposed on said at least one reflective layer; an optically transparent second substrate disposed between the reactive layer and a laser incident surface of the optical storage media; and an oxygen permeable barrier layer disposed between the reactive layer and a laser incident surface of the optical storage media, said reactive layer having an initial percent reflectivity of about 50% or greater and a percent reflectivity of about 45% or less after exposure to oxygen.

Embodiments for an apparatus and method for depositing one or more layers onto a substrate or a freestanding shape inside a reaction chamber operating at a temperature of at least 700° C. and 10 torr are provided. The apparatus is provided with means for defining a volume space in the reaction chamber for pre-reacting the reactant feeds forming at least a reaction precursor in a gaseous form, and a volume space for depositing a coating layer of uniform thickness on the substrate from the reacted precursor. In one embodiment, the means for defining the two different zones comprises a distribution medium separating the pre-reaction zone from the deposition zone, for uniform distribution of the reacted precursor on the substrate. In another embodiment, the means for defining the two different zones comprises a plurality of reactant feed jets or injectors, for creating a jet-interaction zone or pre-reactant zone separate from a deposition zone, for deposing the reacted precursor on the substrate.
