Abstract: A process for forming a capacitor is presented. The process includes providing a laminate including a dielectric layer disposed on a sacrificial substrate, forming a free-standing metallized dielectric layer and packaging the free-standing metallized dielectric layer to form a capacitor. The dielectric layer includes a polyetherimide. The step of forming the free-standing metallized dielectric layer is performed by: (a) disposing a metal layer on the dielectric layer to form a metalized laminate such that a metalized dielectric layer is formed on the sacrificial substrate, and removing the sacrificial substrate to form the free-standing metallized dielectric layer; or (b) removing the sacrificial substrate from the laminate to form a free-standing dielectric layer, and disposing a metal layer on the free-standing dielectric layer to form the free-standing metallized dielectric layer. A capacitor formed by the process is presented. A process for forming a capacitor by a roll-to-roll processing technique is also presented.

Abstract: Imaging panels and imaging systems that may employ use organic photodiodes or other continuous sensors are discussed. The detector panels discussed may have a non-pixelated organic photodiode disposed above a pixelated backplane. In some embodiments, the sensor panels may also include dielectric structures that create buried vias in the region of contact between the organic photodiode and the thin film transistor (TFT) backplane. In some embodiments, the sensor panels may include dielectric structures that separate neighboring pixels. The dielectric structures may decrease thickness inhomogeneity in active areas of the organic photodiode. Detector panels discussed herein may have decreased sensing lag and current leakage, and improved reliability. Methods for formation of organic photodiodes and of dielectric structures are also discussed.

Abstract: A process for fabricating an organic photodetector is presented. The process includes providing an array of thin film transistor assemblies, each thin film transistor assembly including a first electrode disposed on a thin film transistor; disposing an organic semiconductor layer on the array; disposing a second electrode layer including a first inorganic material on the organic semiconductor layer through a shadow mask to form a first etch stop layer; and removing portions of the organic semiconductor layer unprotected by the first etch stop layer using a dry etching process to form a multilayered structure. An organic photodetector, for example an organic x-ray detector fabricated by the process is further presented. An x-ray system including the organic x-ray detector is also presented.

Abstract: A radiation detector assembly including an organic photodetector that generate charge in response to an incident radiation, a thin film transistor array including a plurality of pixels. The plurality of pixels may produce electric signals corresponding to the charge generated by the organic photodetector. The radiation detector assembly also includes a spacer disposed on the thin film transistor array. The spacer surrounds one or more pixels and may confine the organic photodetector within the surrounded one or more pixels such that the surrounded one or more pixels are electrically isolated from a neighboring pixel.
