Making Things With Light: Recent Progress in Multiphoton Absorption Polymerization
Dr. John Fourkas
Department of Chemistry and Biochemistry
University of Maryland College Park

Many new device applications in micro- and nanotechnology require the ability to fabricate complex, 3D structures. Conventional lithographic techniques are not well suited to the creation of many such structures, which has fueled interest in the development of novel fabrication techniques. One rapidly emerging technology for 3D fabrication is multiphoton absorption polymerization (MAP). In MAP, a tightly focused laser beam is used to exposure a photoresist exclusively at the laser focal point. By moving this focal point over a desired pattern in three dimensions, arbitrarily complex structures with feature sizes as small as 100 nm can be created. I will discuss some of our recent progress in expanding the capabilities of MAP as well as in creating functional devices.
