Latest Patents
Spera's latest patents include a tool and method for electroetching. This electroetching tool utilizes a scanned localized application of flowing electrolyte against a workpiece, such as a large area mask with high-density features. The design involves a masked molybdenum plate suspended vertically within a tank that serves as a reservoir for a recirculating electrobyte. The electrolyte is filtered and pumped to traveling cathode assemblies, which apply the flowing electrolyte to both sides of the workpiece through charged orifices. The workpiece is masked on opposite sides with mirror-imaged mask apertures that align with each other. Each orifice consists of an open groove in a polyvinyl chloride block, extending vertically relative to the tank. The groove's bottom is adjacent to a conductive plate, and the assembly moves along guide rails to ensure precise application of the electrolyte.
