SENIC Technical Webinar Series: Session 2 -"Soft Lithography Methods of Fabrication"

April 29, 2020 | 11AM-12PM | SENIC Technical Webinar Series: Session 2 - Soft Lithography Methods of Fabrication 

Paul Joseph, Ph.D., Georgia Institute of Technology

The Southeastern Nanotechnology Infrastructure Corridor (SENIC) housed at the Institute for Electronics and Nanotechnology at Georgia Tech is hosting a series of online technical seminars, from 11am - 12pm, open to the academic and industrial community with an interest in cleanroom fabrication and processing for materials, biological, and electronics research.

We invite you to join us at any of the lectures  by registering at the link at the bottom of the page. On the registration form, please check the seminars for which you are interested (you are not limited in the number) so that appropriate accompanying materials, if needed, are prepared.

Abstract: Soft lithography (SL) refers to a family of techniques for fabricating or replicating structures using elastomeric stamps, molds, and conformable photomasks. Fabrication of microfluidic devices by SL is the most popular approach due to simplicity and low cost. In this approach PDMS (polydimethylsiloxane) is cast on a SU-8 master mold to generate elastomeric stamps that are then sealed against glass slides using oxygen plasma. SL plays a vital role in microfluidics, ranging from simple channel fabrication with inlet/outlet to the creation of micropatterns onto a substrate surface. SL includes a collection of fabrication methods that are all based on using an elastomeric (or PDMS) stamp. These methods with reference to Microfluidics device fabrication (µDF), Replica Molding (REM), Micro-contact printing (µCP), Micro-transfer molding (µTM), and Micro-molding in capillaries (MIMIC) will be presented. The goal for this presentation is to impart a basic understanding of soft lithography for microfluidic applications as practiced in academia and industry.

Bio: Paul J Joseph received his PhD in Physical Chemistry from the University of Madras, India in 1997. From 1997 to 2000, he was a Visiting Scientist for the National Science Council of Taiwan at the National Tsing Hua University. From 2001, he was a Research faculty at the School of Chemical and Biomolecular Engineering, Georgia Institute of Technology, Atlanta, GA. His research focused towards the development of new sacrificial polymeric materials and its application in the field of Microelectronics, Microfluidics, and Microelectromechanical Systems. Dr. Joseph is currently a Principal Research Scientist and is also serving as an external user coordinator at the GT-Institute for Electronics & Nanotechnology and his current research interests are in Nano-biotechnology, Bio- MEMS, Microfluidics, and Biosensors’ application as Diagnostics and Detection Systems. Dr. Joseph’s original research work overall resulted in 85 publications, reports, conference presentations, trade publications, and 7 awarded US and international patents.
