RCA SC-1 Clean

The Standard Clean 1 (SC-1) solution of Ammonium hydroxide and hydrogen peroxide removes organic surface contamination. The Amonium hydroxide serves as a solvating agent and as a complexant for metallic contaminants such as copper. The hydrogen peroxide acts as a powerful solublizing oxidant. The most commonly used ratio is apparently 5:1:1; we use 4:1:1. The reaction takes place at a temperature of 75C in a teflon carrier within a fused quartz bath to avoid contamination from ordinary glass.
