    摘要: A carbon film having an area of insulating material surrounded by an area of conducing material, and an area of material between the area of insulating material and the area of conducting material having a graded dielectric constant which varies from high to low from the area of insulating material to the area of conducting material. An emission site on the carbon film will emit electrons as a function of time, and as a function of distance across an emission site area.

    摘要: A system is disclosed for speeding workpiece thoughput in low pressure, high temperature semiconductor processing reactor. The system includes apparatus for loading a workpiece into a chamber at atmospheric pressure, bringing the chamber down to an intermediate pressure, and heating the wafer while under the intermediate pressure. The chamber is then pumped down to the operating pressure. The preferred embodiments involve single wafer plasma ashers, where a wafer is loaded onto lift pins at a position above a wafer chuck, the pressure is rapidly pumped down to about 40 Torr by rapidly opening and closing an isolation valve, and the wafer is simultaneously lowered to the heated chuck. Alternatively, the wafer can be pre-processed to remove an implanted photoresist crust at a first temperature and the chamber then backfilled to about 40 Torr for further heating to close to the chuck temperature. At 40 Torr, the heat transfer from the chuck to the wafer is relatively fast, but still slow enough to avoid thermal shock. In the interim, the pump line is further pumped down to operating pressure (about 1 Torr) behind the isolation valve. The chamber pressure is then again reduced by opening the isolation valve, and the wafer is processed.

    摘要: A field emitter cell includes a thin-film-edge emitter normal to the gate layer. The field emitter cell may include a conductive substrate layer, an insulator layer having a perforation, a gate layer having a perforation, an emitter layer, and other optional layers. The perforation in the gate layer is larger and concentrically offset with respect to the perforation in the insulating layer and may be of a tapered construction. Alternatively, the perforation in the gate layer may be coincident with, or larger or smaller than, the perforation in the insulating layer, provided that the gate layer is shielded from the emitter from a direct line-of-sight by a nonconducting standoff layer. Optionally, the thin-film-edge emitter may include incorporated nanofilaments. The field emitter cell has low gate current, making it useful for various applications such as field emitter displays, high voltage power switching, microwave, RF amplification and other applications that require high emission currents.
