Latest Patents

One of Hart's latest patents is titled "Developer solution and process for use." This invention presents an improved composition and method for the development of resists. The method involves contacting the resist with a developer solution that includes a source of alkalinity and a cationic surfactant, specifically an ethoxylated and/or propoxylated tallow amine. This enhanced developer solution effectively removes uncured resist from the coated surface.

Another significant patent is "Autodeposition emulsion and methods of using thereof to selectively." This invention describes a process where a coating of resin and photoactive functionality is autodeposited from an emulsion onto a metallic substrate. This method selectively protects the substrate from corrosive environments, such as etchant processes. The emulsion contains an acid and an oxidizing agent, allowing the resin to autodeposit when the substrate is immersed. The resulting coating can be exposed to actinic radiation in an image-wise manner and developed in an alkaline solution, creating circuit traces for circuit boards.
