Common Plasma Cleaning Defects and Solutions
Under-cleaning, over-etching, poor uniformity, redeposition, and surface damage usually point to an unstable recipe, chamber condition, loading pattern, or material mismatch.

Under-cleaning, over-etching, poor uniformity, redeposition, and surface damage usually point to an unstable recipe, chamber condition, loading pattern, or material mismatch.
Learn more →Oxygen, argon, nitrogen, hydrogen-containing blends, and fluorine chemistry produce different reactions. Gas choice depends on the contamination, substrate, downstream process, and safety requirements.
Learn more →Power, pressure, gas flow, treatment time, and chamber geometry determine cleaning rate and surface impact. These settings should be developed as a connected process window rather than adjusted independently.
Learn more →Plasma cleaning uses energetic ions and reactive species to break down organic residue and activate surfaces. The process can reach fine features while limiting liquid chemical use.
