Title: The Innovations of Frederick Claus Zumsteg, Jr.
Introduction
Frederick Claus Zumsteg, Jr. is a notable inventor based in Wilmington, DE (US). He holds three patents that showcase his contributions to the fields of photoresists and lithographic printing technologies. His work has significantly impacted the development of materials used in advanced manufacturing processes.
Latest Patents
One of Zumsteg's latest patents is focused on copolymers for photoresists and processes therefor. This invention describes fluoroolefin/acid group or protected acid group-containing copolymers for photoresist compositions. These copolymer compositions include at least one fluoroolefin, preferably hexafluoroisobutylene, and an acid group or a protected acid group, such as a t-alkyl ester. The resulting materials exhibit high ultraviolet (UV) transparency and developability in basic media, making them particularly useful for lithography at short wavelengths, such as 157 nm and 193 nm.
Another significant patent involves heat-sensitive printing plate precursors. This invention comprises a grained and anodized aluminum substrate treated with a solution of water-soluble salt of a Group IVa metal fluoride, over which a metallic layer, preferably silver, is provided. The precursor allows for imagewise exposure using a high-intensity laser beam, resulting in press-ready plates that demonstrate high image quality and durability without the need for intermediate film and developer chemistry.
Career Highlights
Throughout his career, Zumsteg has worked with prominent companies, including E.I. du Pont de Nemours and Company and Agfa-Gevaert. His experience in these organizations has contributed to his expertise in the development of innovative materials and processes.
Collaborations
Zumsteg has collaborated with notable individuals in his field, including Robert Clayton Wheland and Roger Harquail French. These partnerships have likely enhanced his research and development efforts.
Conclusion
Frederick Claus Zumsteg, Jr. is a distinguished inventor whose work in photoresists and lithographic technologies has led to significant advancements in the industry. His patents reflect a commitment to innovation and excellence in material science.
