Operando Scanning Electron and Microwave Microscopies in Plasmas: A Comparative Analysis



Andrei A. Kolmakov, Alexander Tselev


There exists a great need for an operando nanoscale characterization of evolution of surface composition and morphology during plasma-assisted processing. This includes sputter deposition, plasma-assisted etching, plasma-enhanced atomic layer deposition and other processes relevant for semiconductor and aerospace industries, environmental remediation, and biomedical technology. Recently, we proposed near-field scanning-probe-based microwave imaging as a tool to image surfaces immediately (a few seconds) after plasma processing with a sub-100 nm spatial resolution. In this communication, we report on true operando near-field microwave imaging in plasma and its extension to imaging in SEM.
