Ober Research Group

Research in the Ober Group at Cornell University focuses on creating new polymeric materials and refining their properties with a fundamental understanding of their physical behaviour. We work to apply these novel materials in areas ranging from lithography, to biointerfaces, to flexible electronics. We are a multidisciplinary group consisting of students enrolled in the Departments of Materials Science & Engineering, Chemistry & Chemical Biology, and Chemical and Biomolecular Engineering. Our tools include self-assembly and directed assembly, of which lithography is an important part.

Announcement

Postdoc Positions Available


The Ober and Yu groups at Cornell University are looking for up to two post-doctoral associates with expertise in polymer chemistry to work on a project involving the design of photoresist polymers suitable for extreme ultraviolet lithography. This leading edge, industry-supported program is working to identify breakthrough strategies and new polymer compositions for enabling the next generation of electronics. While technically relevant, the work is expected to lead to high impact publications.

At present we are looking into scissionable polymers for this next generation lithography that form sub-15 nm patterns using PFAS-free patterning chemistry. Familiarity with photoresist chemistry, photoactive compounds and/or expertise in transition metal catalysis is considered an asset.

Those interested in applying for the position, please send your application letter, your resume and have two letters of recommendation forwarded to: cko3@cornell.edu and yz2833@cornell.edu
