摘要： A method for creating emitters of a field emission device is provided. First, a hardmask layer is deposited on a substrate used to form emitters. On the hardmask layer, a photoresist layer is deposited. Islands of photoresist are exposed by an exposing energy through holes in a mask layer. The mask layer is removed and the substrate soft-baked in an oven having an atmosphere of basic gas. Following the soft-bake, the substrate is flood exposed, and then developed using conventional means, leaving behind hardened islands of exposed and baked photoresist. The hardmask layer is etched using the hardened islands as an etching barrier, and the substrate etched with a chemical etchant using the etched hardmask layer as an etching barrier. The etching continues until the substrate material below the etched hardmask layer is formed into an array of points of substrate. Once these emitter sites are formed, a field emission display having uniform emitters can be created.

摘要： A radio frequency communication device and methods of testing and tuning an antenna attached thereto are disclosed. A radio frequency communication device comprises internal circuitry and an antenna having a plurality of antenna segments associated therewith. Each antenna segment is associated with the antenna in either series or parallel relation through at least one of a fuse and an antifuse. In testing and tuning, a comparison is made to indicate whether the antenna is too short or too long. If the antenna is too short, an antenna segment may be attached to the antenna by initiating an antifuse. If the antenna is too long, an antenna segment may be detached from the antenna by blowing a fuse. If it is indeterminate whether the antenna is too short or too long, an antenna segment may be either attached or detached, the test repeated, and the results of the repeated test compared with the prior test to determine whether the correct action was taken.

摘要： A radio frequency communication device and methods of testing and tuning an antenna attached thereto are disclosed. A radio frequency communication device according to the present invention is disclosed comprising internal circuitry and an antenna having a plurality of antenna segments associated therewith. Each antenna segment is associated with the antenna in either series or parallel relation through at least one of a fuse and an antifuse. In testing and tuning, a comparison is made to indicate whether the antenna is too short or too long. If the antenna is too short, an antenna segment may be attached to the antenna by initiating an antifuse. If the antenna is too long, an antenna segment may be detached from the antenna by blowing a fuse. If it is indeterminate whether the antenna is too short or too long, an antenna segment may be either attached or detached, the test repeated, and the results of the repeated test compared with the prior test to determine whether the correct action was taken. If the results improved, the correct action may be repeated if needed. If the results did not improve, an opposing action may be initiated. Tuning the antenna by adjusting its length rather than adjusting the values of impedance elements coupled to the antenna reduces power consumption and heat, and simplifies tuning of antennas for high frequency applications.

摘要： The disclosed method for forming a field emission display includes forming a cathode and an anode, forming a plurality of photoresist posts over the cathode, and coating the posts with a coating material. The coating material forms sidewalls around the posts. The photoresist posts may then be removed from within the sidewalls. The anode may then be fitted onto the sidewalls so that the sidewalls function as spacers in the field emission display.
