摘要： In accordance with one aspect of the invention, a semiconductor processing method of treating a semiconductor wafer provides a wafer within a volume of liquid. The wafer has some electrically conductive material formed thereover. The volume of liquid within the chamber with the wafer therein is established at a pressure of greater than 1 atmosphere and at a temperature of at least 200° C. and below and within 10% of the melting point of the electrically conductive material. In accordance with another aspect, the volume of liquid within the chamber with the wafer therein is established at a pressure of greater than 1 atmosphere. After establishing the pressure of greater than 1 atmosphere, the pressure of the volume of liquid is lowered to a point effective to vaporize said liquid and the vapor is withdrawn from the chamber. In accordance with still another aspect, a semiconductor processing method of increasing planarity of an outer surface on a substrate comprises exposing the outer surface to a volume of liquid at a pressure of greater than about 200 atmospheres. The invention has particular utility to more completely filling contact openings with electrically conductive material, and to increasing substrate planarity. A typical preferred treatment is expected to last anywhere from seconds up to ten minutes or more.

摘要： A field emission display includes electrostatic discharge protection circuits coupled to an emitter substrate and an extraction grid. In the preferred embodiment, the electrostatic discharge circuit includes diodes reverse biased between grid sections and a first reference potential or between row lines and a second reference potential. The diodes provide a current path to discharge static voltage and thereby prevent a high voltage differential from being maintained between the emitter sets and the extraction grids. The diodes thereby prevent the emitter sets from emitting electrons at a high rate that may damage or destroy the emitter sets. In one embodiment, the diodes are coupled directly between the grid sections and the row lines. In one embodiment, the diodes are formed in an insulative layer carrying the grid sections. In another embodiment, the diodes are integrated into the emitter substrate.
