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.

A pyrolytic boron-nitride material is disclosed having an in-plane thermal conductivity of no more than about 30 W/m-K and a through-plane thermal conductivity of no more than about 2 W/m-K. The density is less than 1.85 g/cc.
摘要:
A barrier coating of organic-inorganic composition, the barrier coating having optical properties that are substantially uniform along an axis of light transmission, said axis oriented substantially perpendicular to the surface of the coating.
摘要:
Methods and devices for coating an interior surface of a container using ICPECVD are provided. In one embodiment, a method of coating an interior surface of a container comprises: depositing a barrier film on the interior surface of the container using inductively coupled plasma-enhanced chemical-vapor deposition.
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.
摘要:
An etch resistant heater for use in a wafer processing assembly with an excellent ramp rate of at least 20° C. per minute. The heater is coated with a protective overcoating layer allowing the heater to have a radiation efficiency above 70% at elevated heater temperatures of >1500° C., and an etch rate in NF3 at 600° C. of less than 100 A/min.
摘要:
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 100 torr are provided. The apparatus is provided with a feeding system having injection means for differential pre-reactions and/or pre-treating of a plurality of gases or gas mixtures, tailoring the distribution of a plurality of gas-phase species, yielding a deposit that is substantially uniform in thickness and chemical composition along the substrate surface. In one embodiment, the apparatus further comprises a sacrificial substrate that further helps achieving thickness and chemical uniformity on the substrate, by imitating a continuous surface to deposit on and thus preventing any disturbances in the flow pattern especially towards the edge of the substrate.
