Granted: 1990-05-23
Abstract: New etch monitoring and thickness measurement techniques which are more accurate than previous techniques. In accordance with the invention, the etch depth of a substrate region undergoing etching is monitored, or the thickness of the region is measured, by impinging the region with light and detecting the intensity of the reflected light. In contrast to the previous techniques, the incident light is chosen so that a substrate region underlying, and/or a patterned substrate region overlying, the substrate region of interest is substantially opaque to the incident light, which precludes the formation of signals unrelated to etch depth or thickness.

Abstract: For some applications of slide layers, for example in connecting rod bearings of internal combustion engines, for individual sites of a formed piece, high load bearing capability are required while for other places of the same formed piece good embedding abilities are demanded. A composite material with a slide layer applied by cathode sputtering of a tightly cohesive matrix and an insoluble component distributed statistically in it, is adapted to these opposite demands in that the diameter of the particle of the insoluble material has gradients at predetermined sites, which extend parallel to the surface of the slide layer, and to which slide layer hardness gradients correspond. These gradients are generated during the cathode sputtering process in the substrate to be coated to form a growing slide layer having temperature gradients which are maintained and which extend parallel to the substrate surface.

Abstract: A semiconductor buffer circuit and buffering method for driving capacitive loads that enhances the current sinking and sourcing drive characteristics at times when the input signal is changing. Two transistors (12,14) are used, a source follower transistor (12) and a current source pull-down transistor (14), with an input signal (Vin) applied to the control input of the source follower transistor (12). The complement (Vin) of the input signal (Vin) is capacitively coupled to the control input of the current source pull-down transistor (14). As a result, changes in the input voltage increase or decrease the conductivity of the current source pull-down transistor (14), thereby allowing the capacitive load (13) to be charged and discharged more efficiently.
