|Physics colloquium on direct write technology|
Dr. Orven F. Swenson from North Dakota State University will present a colloquium with title "Direct Write Technology Enhancement Through Applied Optics" at 4 p.m. Friday, Dec. 14, in 211 Witmer Hall. Coffee and cookies will be served at 3:30 p.m. in 215 Witmer Hall.
Direct write technologies are rapidly reaching the goal of printing an entire microelectronic device on flexible polymeric substrates. An interdisciplinary team at the Center for Nanoscale Science and Engineering has been a leader in advancing a type of direct write tool, the Mesoscale Maskless Materials Deposition (M3D) system, for printing microcircuits on polymide substrates. M3D is a focused aerosol beam approach sold by Optomec. I will discuss two optics enabled enhancements: aerosol beam collimation resulting from a new mathematical model of the aerosol dynamics verified by laser scatter imaging and laser sintering of M3D printed silver nano-ink conductors.
