Latest Patents

Harold A. Levine holds a patent for a "Lift-off method of fabricating thin films and a structure utilizable as." This method is designed for forming thin film patterns in the fabrication of integrated circuits. The process involves depositing a bottom layer of positive photoresist material on a substrate, followed by a discrete light-transparent top layer. The top layer is less solubilized in developer after exposure to light than the bottom layer. An intermediate layer of light-transparent polymeric material is often used to separate the two layers. The composite structure is then exposed to a selected pattern of light, and developer is applied to both layers. The resulting structure allows for the deposition of thin films through coincident aperture patterns.
