Lecture
This lecture covers the importance of patterning techniques in creating functional electronic devices from organic semiconductor thin films, including organic photovoltaics, field-effect transistors, and light-emitting diodes. It discusses additive and subtractive patterning, stencil lithography, resist-based lithography techniques, photolithography, screen printing, inkjet printing, gravure printing, and roll-to-roll processes for large-scale, low-cost device fabrication.
