Abstract: An apparatus for endpoint detection during polish, being used to monitor the surface polishing status of a polishing surface of a workpiece, is disclosed, which comprises: a probe, being positioned above the workpiece by a height; and at least a sensing element, being disposed on the probe at a position corresponding to the polishing surface, capable of sensing the thickness variation of the workpiece during a polishing process as it is performing a surface dynamic scan upon the workpiece in rotating while it is being driven to proceed a linear motion of displacement. Preferably, the sensing element can be a device selected from the group consisting of an optical sensor, an eddy current sensor and the combination of the two for carrying out optical detection and magnetic flux detection.

Abstract: A system and method of capturing a skin print from skin having ridges and valleys. A skin print sensor having a return/supply contact and a plurality of contact pads is provided. A finger is applied to the skin print sensor and data is stored representative of contact pads in contact with skin ridges.

Abstract: In a method of forming a conductive path on a substrate, a layer of metallic nanoparticles is printed on the substrate and a conductive organic material is also printed, such that the conductive organic material is interspersed with the layer of metallic nanoparticles to thereby enhance one or more electrical properties of the conductive path.

Abstract: A system for delivering material onto a substrate. The system includes a jetting system having a reservoir containing the material and the reservoir includes a nozzle through which the material is expelled from the reservoir. An arcuate section is positioned between the reservoir and the nozzle. The material is configured to travel from the reservoir, through the arcuate section, and through the nozzle. The system also includes a means for applying pressure on the material contained in the reservoir, wherein the material is expelled from the reservoir through application of pressure by the means for applying pressure to thereby create a column of the material from the nozzle. A means for producing pressure modulations is located proximate the nozzle and is configured to substantially regulate formation of droplets from the column of the material. In addition, the system includes a charging ring configured to induce an electrical charge to selective ones of the droplets as they pass through the charging ring.

Abstract: An assembly for depositing material onto a substrate includes a reservoir containing the material. The reservoir also includes a nozzle through which the material is jetted and formed into droplets. The droplets travel through flight paths prior to deposition onto the substrate. The assembly includes a charging ring for inducing an electrical charge to one or more of the droplets and a plurality of deflection plates for controlling the flight paths of the droplets. In addition, the assembly also includes a droplet manipulating device configured to manipulate the droplets at least one of during the flight paths and after deposition of the droplets onto the substrate.

Abstract: A data storage device includes a conductive probe having a tip; a substrate; and a data storage medium including a layer of poled ferroelectric material. The ferroelectric layer is between the tip and the substrate.
