摘要： A method of manufacturing and a structure of a semiconductor device is disclosed whereby a gate insulating layer, a polycrystalline silicon layer, a tungsten silicide layer and a first insulating layer are formed on a semiconductor substrate. Gates are formed by the removal of the layers by dry etching, wherein the etch rate of the tungsten silicide layer is faster than the other layers, thereby forming an undercut region in the tungsten silicide layer. A second insulating layer is formed on the surface of the resultant structure to form spacers, and a contact window is formed between the gates via an etching process. The second insulating layer portion which forms the spacers need not be thick to prevent etching of the gates when forming the contact window, therefore good step coverage is achieved and reliability of the device is increased.

摘要： The profile of a tool or other object having a flat reference plane is illuminated by interfering beams of coherent light to generate a striped light pattern which at any point deviates from straight lines as a function of the surface spacing from the reference plane. A camera image of the pattern taken at an angle to the beams is processed by an image analysis program which converts the stripes to lines corresponding to light peaks and valleys of the pattern. Tool wear or object profile is determined from the deviation of lines from straight reference lines. The program includes algorithms for identifying peak and valley line segments, determining the segments which are neighbors of other segments, and connecting lines according to a set of rules and constraints which use the data on neighbor segments and the proximity of segment end points.
