Functions and scripts for image-processing and other data analysis used in undergraduate project studying fluid dynamical instabilities while rinsing a silicon wafer on a spin coater. The goal of this project was to identify the conditions that led to a catastrophic flow instability while cleaning silicon wafers to improve a novel, green method for wafer-cleaning developed by Lam Research.
The work for the project was performed by Andy Ylitalo under the mentorship of John M. Frostad and with help from Dan Walls in Gerald Fuller's lab at Stanford University from 2015-2017. Andy Ylitalo developed the base of the image-processing and John Frostad added key functionalities.
Additional analysis and publications were completed 2017 - 2019.
