Abstract (Deutsch)

The aim of this project is two-fold: to develop a fast response bubble detector which both detects the presence of microbubbles and evaluates their size, and to integrate this bubble detector into a non-invasive, non-intrusive, contact-less laser-based flowmeter for dispensing extremely high purity, microbubble-free liquids for high-resolution (sub- 100 nm) wafer fabrication. The combined instrument will enable effective elimination of bubble-induced defects in the thin photoresist layers spun on silicon wafers.
