Latest Patents
Ralph A. Dyrsten holds a patent for a "Method for etching a dielectric layer over a semiconductor substrate." This invention involves a wet etch bath that holds a wet etchant for etching a dielectric over a semiconductor substrate. The wet etch bath consists of a tub separated from a reservoir by a wall. The tub is filled with the wet etchant to a height of the wall, while the reservoir is filled with the wet etchant to a height less than that of the wall. A pump coupled to the reservoir pumps the wet etchant through an osmotic membrane degasifier to the tub. Adding the wet etchant to the tub causes it to cascade over the wall back to the reservoir. The osmotic membrane degasifier reduces the concentration of a reactive agent in the wet etchant. This innovative approach enhances the efficiency of the etching process in semiconductor manufacturing.
