Abstract

In this study, critical hardware and process parameters are evaluated for their effect on performance in megasonic cleaning applications. Experimental data is presented which shows the impact of transducer design, bath temperature, process time, SC1 chemistry, and wafer gap spacing on particle removal and surface roughness. The ability to remove particles smaller than 0.1 um in size is also demonstrated.
