摘要： A photomask for use in manufacturing integrated circuits is fabricated by coating a thin film of organic material, generally a solution of a thermally decomposable hydrocarbon, onto a glass plate and heating it in a reducing atmosphere to convert it into carbon. The carbon layer is masked and etched; for example, in an oxygen plasma, to produce the mask.

摘要： An improved lead for surface-mounted electronic components is described. The improved lead includes an opening through the portion of the lead to be placed in contact with the printed circuit board for soldering. The opening, having a diameter approximately equal to the thickness of the lead, enables the detection of correctly-soldered joints using automated inspection equipment. When the lead is correctly soldered, solder is drawn by capillary action into the opening where it forms a meniscus. By automatically detecting the curvature of the meniscus, the quality of the solder joint may be determined.

摘要： A method for directly measuring the area of a topological surface with an arbitrary boundary shape lying in a fixed elevation different from a fixed surrounding surface elevation relies upon binocular stereo vision. Three stereo correlation measurements are made, one over a window entirely within the surface of interest, a second over a window outside the surface of interest and within the surrounding area, and a third over a window fully containing the surface of interest as well as some of the surrounding area. The correlation measured in the third case is the linear sum of the correlation value over each of the first two cases weighted by the proportion of the window that the two surfaces occupy.
