This lecture by the instructor covers the technique of microcontact printing (UCP) for nanometer scale lithography. It explains the process of using a stamp to transfer patterns onto substrates, highlighting the challenges and limitations. The lecture also discusses biopatterning and showcases examples of layered hybrid stamps for improved substrate adaptation. Additionally, it provides an overview of existing and upcoming nano-fabrication methods, including stencil lithography, and outlines the basics of lithography, electron beam lithography, focused ion beam fabrication, nano-imprint lithography, and scanning probe lithography.
