Synopsis:

The goal of the course is to familiarize the students both with the microtechnology and nanotechnology tools, materials and directions in order to facilitate a confident choice of fabrication method for a particular miniaturization problem. The methods surveyed include synthesis, artificially multilayered materials, processing of nanomaterials, their characterization, properties and applications in nanoelectronics. The synergy between theory of the synthesis of nanomaterials, molecular engineering, nano- and microtechnology may prove the most fruitful study domain for decades to come.
