Exploring the Versatility of End-Grafted Polymer Brushes for High-Precision Nanopatterning

We explore end-grafted polymer and peptoid brushes for nanoscale surface modification. Integrated with advanced lithographic techniques, these brushes enable precise adsorption, interfacial tuning, and interfacing between inorganic surfaces and biological matter. We showcase examples ranging from biomimetic polymers for semiconductor/bio interfaces to directed self-assembly for EUV lithography and selective deposition.

About Ricardo Ruiz

Ricardo Ruiz is a staff scientist at The Molecular Foundry at Lawrence Berkeley National Laboratory. Additionally, he serves as the Director of the Center for High Precision Patterning Science (CHiPPS), a DOE-BES funded Energy Frontier Research Center dedicated to advancing patterning science in the Extreme Ultraviolet lithography era for semiconductor manufacturing. Dr. Ruiz specializes in nanofabrication, lithographic patterning, and self-assembly. From 2006 to 2019, he held various appointments at Hitachi GST/HGST/Western Digital, where he made significant contributions to magnetic bit patterned media and non-volatile memories, and managed a research group focused on block copolymer and nanoparticle lithography. Dr. Ruiz is a fellow of the American Physical Society. He earned his PhD in Physics from Vanderbilt University in 2003 and completed postdoctoral fellowships at Cornell University and IBM T.J. Watson.
