摘要： A method comprises processing a substrate in a gas enclosure to form a film on one or more portions of the substrate. The method further comprises, while processing the substrate, circulating gas along a circulation path through the gas enclosure. Circulating the gas may comprise flowing gas through an exhaust housing enclosing a printhead assembly housed in the gas enclosure and filtering the gas flowing downstream of the printhead assembly from the exhaust housing.

摘要： Print materials described herein include a first polymerization initiator comprising an initiator material having a thermal decomposition rate and a peak photo-initiated decomposition rate, wherein the thermal dissociation rate is higher than the peak photo-initiated decomposition rate; a vinylic monomer; a polyfunctional monomer; scattering particles; and quantum dots. Methods of making a quantum dot material using such print materials, and of incorporating into light emitting devices, are also described.

摘要： A printer includes a substrate support, a printhead assembly, first and second actuators, and a controller. The printhead assembly deposits material on a substrate supported on the substrate support. The first actuator is disposed at a side of the substrate support and coupled to a first linear track disposed along the side of the substrate support and oriented in a first direction. The second actuator is disposed at an end of the substrate support and coupled to a second linear track disposed along the end of the substrate support and oriented in a second direction perpendicular to the first direction. The first and second actuators are positioned to engage with the substrate simultaneously. The controller moves the first and second actuators together to rotate the substrate.

摘要： A system may include a support surface for supporting a substrate, a plurality of first passages arranged to distribute flows of a first gas to establish a gas bearing to float the substrate above the support surface, and a plurality of second passages arranged to distribute flows of a second gas to convey the substrate along the support surface. A method may include floating a substrate above a support surface of a substrate support apparatus via a gas bearing; and while floating the substrate, conveying the substrate along the support surface by flowing gas toward a surface of the substrate and in a nonperpendicular direction relative to the surface of the substrate.

摘要： What is disclosed herein are embodiments of an enclosed manufacturing system configured to provide a controlled process environment for various articles of manufacture requiring a controlled process environment, and additionally to contain a process environment within the enclosure during periods of external access to the interior of the enclosed manufacturing system. Various embodiments of manufacturing systems of the present teaching can contain the environment within a manufacturing enclosure so as to minimize the interaction of an environment external to a manufacturing enclosure with the internal enclosure environment.

摘要： An ink printing process employs per-nozzle droplet volume measurement and processing software that plans droplet combinations to reach specific aggregate ink fills per target region, guaranteeing compliance with minimum and maximum ink fills set by specification. In various embodiments, different droplet combinations are produced through different print head/substrate scan offsets, offsets between print heads, the use of different nozzle drive waveforms, and/or other techniques. Optionally, patterns of fill variation can be introduced so as to mitigate observable line effects in a finished display device. The disclosed techniques have many other possible applications.

摘要： Ligand-capped scattering nanoparticles, curable ink compositions containing the ligand-capped scattering nanoparticles, and methods of forming films from the ink compositions are provided. Also provided are cured films formed by curing the ink compositions and photonic devices incorporating the films. The ligands bound to the inorganic scattering nanoparticles include a head group and a tail group. The head group includes a polyamine chain and binds the ligands to the nanoparticle surface. The tail group includes a polyalkylene oxide chain.

摘要： A printer deposits material onto a substrate as part of a manufacturing process for an electronic product; at least one transported component experiences error, which affects the deposition. This error is mitigated using transducers that equalize position of the component, e.g., to provide an “ideal” conveyance path, thereby permitting precise droplet placement notwithstanding the error. In one embodiment, an optical guide (e.g., using a laser) is used to define a desired path; sensors mounted to the component dynamically detect deviation from this path, with this deviation then being used to drive the transducers to immediately counteract the deviation. This error correction scheme can be applied to correct for more than type of transport error, for example, to correct for error in a substrate transport path, a printhead transport path and/or split-axis transport non-orthogonality.
