Abstract: A method of depositing material onto a base portion of a wafer is disclosed. The method includes forming a bevel into a portion of a surface of the base portion of the wafer and depositing a first layer of conductive material onto the beveled portion of the base portion so that part of the first layer includes a wedge shape above the surface of the base portion. A second layer of conductive material is deposited onto the base portion including the portion of the base portion onto which the first layer of material is deposited.

Abstract: Disclosed is a coating system for the selective application of coatings to substrates to apply a uniform coating to selected areas of the substrate without the need for masking. The system comprises a first coating applicator for coating large areas of the substrate, a second coating applicator for coating small areas of the substrate, a motion and positioning system for both coating applicators and a system controller. Also disclosed is an ultrasonic spray coating system comprising an ultrasonic transducer with spray forming head, integrated fluid delivery device with air and liquid supply passage ways, support brackets and an ultrasonic power generator.

Abstract: Disclosed is an ultrasonic spray coating system comprising an ultrasonic spray head with integrated fluid delivery system (IFDS), which consists of an ultrasonic transducer with a spray forming tip, an ultrasonic generator, an external liquid applicator, a precision liquid delivery system and air directors. The coating liquid is delivered to the spray forming tip on the ultrasonic transducer from an external liquid applicator. The liquid is stored in a pressurized reservoir and fed to the liquid applicator by a precision liquid delivery system. The ultrasonic vibrations of the spray forming tip break up the liquid into small droplets and propel them from the tip in the form of a spray. The spray produced with ultrasonic energy alone is a very narrow “sheet-like” pattern. The width of the spray pattern produced is equal to the width of the spray forming tip (2 mm to 4 mm). Air directors are used to produce air streams to further shape and accelerate the ultrasonically produced spray.
