From the last post, I had successfully manufactured waveguide on top of our porous silicon nanomembrane chip. However, the proof that light can transmit through the waveguide was not accomplished until last week. The problems I was experiencing included insufficient…

Abstract: In this project, we want to explore the possibility of detecting molecules in nanopores by building waveguides upon a silicon nanomembrane chip. The first experiment is performed by sending 650nm laser light onto our waveguides and detecting the light…

There are four main challenges for making such a thin photoresist gasket on a little chip. Q1: How can I get under 1um thickness photoresist gasket? Q2: Is the adhesion of photoresist gasket strong enough for further usage? Q3: How…

This is my (Jim) summary of the results thus far for NPN vs NPN-O and Front Side/Back side comparisons. More to come … *************************************************************************************************************   As thesis indicated, the thicker membrane is, the larger average pore size will be.
