Latest Patents

Donoghue holds a patent for a method titled "Method for etching sidewall polymer and other residues from the surface of semiconductor devices." This patent describes a technique for removing both organic and inorganic residues or polymers from the surfaces of semiconductor devices. The method utilizes a combination of etchant gases, including water vapor generated by a catalytic moisture generator (CMG). The water vapor is produced by introducing oxygen and a hydrogen-containing forming gas, which includes hydrogen and at least one dilutant gas, into the CMG. This water vapor is then introduced into a reaction chamber along with other etchant gases to treat the surface of a semiconductor device. The flow rate of the water vapor can be controlled by adjusting the flow rates of the gases entering the CMG.
