Abstract
Microdimensional patterning of organic polymers is required for the development of plastic electronics. Traditional top-down lithography is costly economically and wastes a lot of materials. We offer an in-situ patterning approach known as microbubble lithography (MBL) for patterning dispersed organic polymers in micro dimensions. Despite the method's broad use, we chose a model semi-conducting organic plastic (or polymer) called poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as a typical organic system for proof of concept. Thus, we create permanent patterns of PEDOT:PSS on glass, which are then investigated using various characterisation techniques like scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDAX) and IV properties. We also see conductivity improvements in the patterned polymer without the usage of external doping agents or invasive chemical treatments. These findings present an alternative, more cost-effective, and environmentally friendly method for developing microelectronics devices employing MBL.

Anand Dev Ranjan is a senior research fellow at IISER Kolkata in India, working under Prof. Ayan Banerjee. His current research interests focus on the study and application of microbubbles produced inside optical tweezers. Anand's research is multidisciplinary, drawing on techniques from physics, chemistry, and biology. This has also helped him secure one of the earliest patents in his department at IISER Kolkata for the use of microbubbles. Prior to pursuing doctoral studies, Anand was awarded the junior research scholarship by the Government of India. He completed his master's degree at the Indian Institute of Technology, Madras. Aside from research, Anand enjoys writing poetry and creating music. He believes that disseminating knowledge to future generations is just as vital as conducting research, so he actively participates in a variety of science outreach initiatives, including performing some fundamental science experiments for school children.
