Title: Leonard J Fried: Innovator in Thin Film Fabrication
Introduction
Leonard J Fried is a notable inventor based in Poughkeepsie, NY (US). He has made significant contributions to the field of integrated circuit fabrication, particularly through his innovative methods for creating thin film patterns.
Latest Patents
Fried holds a patent for a lift-off method of fabricating thin films. This method is designed for use in 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 of positive photoresist material. This top layer is less solubilized in developer after exposure to light than the bottom layer. An intermediate layer of light-transparent polymeric material, which is immiscible in the bottom layer, is also utilized. The composite structure is 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, with the photoresist layer serving as a deposition mask. Fried's patent represents a significant advancement in the efficiency and precision of integrated circuit manufacturing.
