The etch rates and uniformity of deposition at various temperatures are reported.Publication Effect of Developer Temperature on Photoresist Contrast in Grayscale Lithography(2021-05-12) Farnan, Dale; Watson, George PatrickSPR 220-3 photoresist was spin-coated onto a silicon wafer, exposed using a Heidelberg DWL66+ laserwriter at different laser powers, and developed at different temperatures. The effect of developer temperature on photoresist contrast was examined. Results show that increasing developer temperature decreased photoresist contrast and increased required dose.Publication Improving Healthspan through Patient-Derived Artificial Organs from Induced Pluripotent Stem Cells and Two-Photon Polymerization(2021-09-16) Espenshade, ConnorSenescence, from the shortening of telomeres, accumulation of mutations, epigenetic hypomethylation, and other causes, begins an eventual cycle of decline in every patient. Stem cells disappear as a function of age, which in turn impairs cellular replication. Moreover, when fully differentiated cells are induced back into induced pluripotent stem cells (iPSCs), they not only revert to a state of pre-differentiation, but also to a younger cellular age. Their aging clocks turn back: their telomeres become longer and DNA methylation reverts back to an earlier age. It should therefore be possible to use iPSCs to replace the missing stem cells from aged organs and tissues and to replace existing, older tissue with younger cells. In order to accomplish this, this paper will also explore new nanotechnological mechanisms in generating patient-specific scaffolds, including two-photon polymerization, a fabrication process that uses a specifically focused, near-infrared laser to build three-dimensional scaffolds. This paper finally proposes a mechanism to apply iPSCs as preventative medicine, to replace aging organs before they fail and unwind the aging clock to lengthen healthspan.Publication Priming Methods for PDMS Devices Study Report(2015-11-09) Wen, Justin
