Latest Patents

Heybruck held a patent for a reactive ion etching chamber. This chamber structure is designed to provide operation with uniformity in electric field and generated plasma, ensuring uniform, contaminant-free etching over large batches of silicon wafers. The anode chamber structure is cylindrical and physically symmetrical with respect to a round cathode plate. The internal surfaces of the chamber are free of any apertures, holes, or recesses, having an opening dimension larger than one-tenth the thickness of plasma 'dark space'. Under normal reactive ion etching conditions, this opening dimension is 1.5 mm or less, and the distance between the cathode and anode internal surface is 3.0 mm or less. This innovation has significantly improved the etching process in semiconductor manufacturing.
