| Abstract: We describe the design and performance of an atomic force microscope (AFM) combined with a miniaturized inductively coupled plasma (ICP) source working at a radio frequency (rf) of 27.12MHz. State-of-the-art scanning probe microscopes (SPMs) have limited in-situ sample treatment capabilities. Aggressive treatments like plasma etching or harsh treatments like etching in aggressive liquids typically require the removal of the sample from the microscope. Consequently, time consuming procedures are required if the same sample spot has to be imaged after successive processing steps. We have developed a first prototype of a SPM which features a quasi in-situ sample treatment using a modified commercial atomic force microscope (DimensionTM 3100, Veeco Instruments Inc., USA). A sample holder is positioned in a special reactor chamber; the AFM tip can be retracted by several millimeters so that the chamber can be closed for a treatment procedure. Most importantly, after the treatment the tip is moved back to the sample with a lateral drift per process step in the 20 nm regime. The performance of the prototype is characterized by consecutive plasma etching of a nanostructured polymer film. |
