Abstract: The disclosure relates to a method for depositing films on a substrate which may form part of an LED or other types of display. In one embodiment, the disclosure relates to an apparatus for depositing ink on a substrate. The apparatus includes a chamber for receiving ink; a discharge nozzle having an inlet port and an outlet port, the discharge nozzle receiving a quantity of ink from the chamber at the inlet port and dispensing the quantity of ink from the outlet port; and a dispenser for metering the quantity of ink from the chamber to the inlet port of the discharge nozzle; wherein the chamber receives ink in liquid form having a plurality of suspended particles and the quantity of ink is pulsatingly metered from the chamber to the discharge nozzle; and the discharge nozzle evaporates the carrier liquid and deposits the solid particles on the substrate.

Abstract: An active acoustic system includes a thin-film sheet having an array of piezoelectric microstructures embossed in the film. Each piezoelectric microstructure may act as a speaker and/or a microphone. A control circuit is configured to individually address the piezoelectric microstructures to provide a separate voltage signal to, or receive a separate voltage signal from, each piezoelectric microstructure.

Abstract: Described are devices and methods for measuring semiconductor materials, devices, circuits, and systems. The device includes a probe head that accepts multiple optical assemblies. At least one optical assembly provides a light source, and at least one optical assembly provides a detector. Both are coupled to the probe head. The optical assemblies may be manually or automatically adjustable using kinematic mounts, and may include optical fibers for conveying light to and from a sample. Each optical assembly may include a lens stack or an objective. Illumination and collection assemblies may share a common focal point, and different subsets of assemblies may share different focal points. The device may include a sample bed for imaging multiple samples at once, and may be coupled to a control system for automatically positioning the samples and/or the optical assemblies.

Abstract: The disclosure relates to method and apparatus for micro-contact printing of micro-electromechanical systems (“MEMS”) in a solvent-free environment. The disclosed embodiments enable forming a composite membrane over a parylene layer and transferring the composite structure to a receiving structure to form one or more microcavities covered by the composite membrane. The parylene film may have a thickness in the range of about 100 nm-2 microns; 100 nm-1 micron, 200-300 nm, 300-500 nm, 500 nm to 1 micron and 1-30 microns. Next, one or more secondary layers are formed over the parylene to create a composite membrane. The composite membrane may have a thickness of about 100 nm to 700 nm to several microns. The composite membrane's deflection in response to external forces can be measured to provide a contact-less detector. Conversely, the composite membrane may be actuated using an external bias to cause deflection commensurate with the applied bias. Applications of the disclosed embodiments include tunable lasers, microphones, microspeakers, remotely-activated contact-less pressure sensors and the like.
