Abstract: Embodiments of the present disclosure relate to an apparatus and methods for forming arrays of EL devices and forming the EL devices with overlapped mask plates. The methods utilize overlapping a first mask plate and a second mask plate to form a mask arrangement having first apertures of the first mask plate overlapped with second apertures of the second mask plate forming one or more opening areas. A material is evaporated through the mask arrangement such that layers of the material are formed in a device area of the EL devices. The device area of each of the EL devices corresponds to the opening area of the mask arrangement of the first mask plate and the second mask plate. The method described herein allows for a higher density of the EL devices and creates a smaller deposition area due to the opening area of the mask arrangement.

Abstract: A superconducting nanowire single photon detector (SNSPD) device includes a substrate having a top surface, an optical waveguide on the top surface of the substrate to receive light propagating substantially parallel to the top surface of the substrate, a seed layer of metal nitride on the optical waveguide, and a superconductive wire on the seed layer. The superconductive wire is a metal nitride different from the metal nitride of the seed layer and is optically coupled to the optical waveguide.

Abstract: A light-emitting diode display including a substrate having a driving circuitry and a plurality of light emitting diode structures disposed on the substrate. Each light-emitting diode structure has a light emitting diode with a light emission zone having a planar portion, and a pigmentless light extraction layer of a UV-cured ink disposed over the light-emitting diode. The light extraction layer has a gradient in index of refraction along an axis normal to the planar portion, and the index of refraction of the light extraction layer decreases with distance from the planar portion.

Abstract: Embodiments described herein relate to methods for fabricating waveguide structures utilizing substrates. The waveguide structures are formed having input coupling regions, waveguide regions, and output coupling regions formed from substrates. The regions are formed by imprinting stamps into resists disposed on hard masks formed on surfaces of the substrates to form positive waveguide patterns. Portions of the positive waveguide patterns and the hard masks formed under the portions are removed. The substrates are masked and etched to form gratings in the input coupling regions and the output coupling regions. Residual portions of the positive waveguide patterns and the hard masks disposed under the residual portions are removed to form waveguide structures having input coupling regions, waveguide regions, and output coupling regions formed from substrates.

Abstract: An organic light-emitting diode (OLED) deposition system includes two deposition chambers, a transfer chamber between the two deposition chambers, a metrology system having one or more sensors to perform measurements of the workpiece within the transfer chamber, and a control system to cause the system to form an organic light-emitting diode layer stack on the workpiece. Vacuum is maintained around the workpiece while the workpiece is transferred between the two deposition chambers and while retaining the workpiece within the transfer chamber. The control system is configured to cause the two deposition chambers to deposit two layers of organic material onto the workpiece, and to receive a first plurality of measurements of the workpiece in the transfer chamber from the metrology system.
