Zhichun Zhang

Zhichun Zhang, Ph.D., is a patent agent in Sterne Kessler’s Electronics Practice Group. Zhichun assists in preparation and prosecution of U.S. and foreign patent applications. His technical areas of expertise include semiconductor material/device fabrication, characterization and analysis, advanced semiconductor process and product development, analog and digital circuits, optics, nanotechnology, microelectronics, Ultra-High Vacuum (UHV) and cryogenic systems.

Zhichun received his M.S. and Ph.D. degrees in electrical engineering from The Ohio State University. His graduate research focused on the characterization and analysis of the process dependence of defects and dopants in wide bandgap semiconductor materials and devices using multiple nanoscale and depth-resolved characterization techniques to develop manufacturing-worthy process and products.

Prior to joining Sterne Kessler, Zhichun worked on characterization and failure analysis of advanced 14nm FinFET process development as an advisory engineer/scientist for three years with a leading global semiconductor research company, which was acquired by a leading semiconductor foundry. Zhichun continued working on leading-edge 7nm FinFET yield issues and process/product development as a technical staff member for two years after the acquisition.
