Title: Innovations by Peter H. Berasi: Pioneering Metal Mask Technologies
Introduction
Peter H. Berasi, an accomplished inventor based in Hopewell Junction, NY, has made significant contributions to the field of technology with four patents to his name. His innovative work focuses primarily on advanced manufacturing processes for integrated circuits, particularly in the development of metal masks.
Latest Patents
Among his latest patents, Berasi's "Moly mask construction and process" stands out as a noteworthy invention. This patent discloses a method for manufacturing a metal mask designed for an integrated circuit chip interconnect solder bump. The process details the deposition of a thick photoresist on both sides of a substantial molybdenum foil sheet—at least 8 mils thick—and emphasizes the importance of achieving precise openings with diameters of at least 5 mil. Furthermore, the patented method intricately outlines how to etch both sides of the molybdenum foil using a low etchant spray pressure to create vias with exact dimensions.
Another notable patent by Berasi is titled "Fine-dimension masks and related processes." This invention describes a process that enhances the manufacturing of masks by developing resist layers over a masking layer. The process involves transferring reduced-sized openings from glass masters into the resist layers, followed by meticulous etching techniques that ensure high precision throughout the manufacturing process.
