Particle

03 Cleanroom, Vacuum, Gases & Facilities

Definition

A particle is a discrete contaminant, solid or liquid, whose presence on or near semiconductor wafers can interfere with fabrication and create defects.

Application

Monitored and controlled in cleanrooms, process tools, wafer handling, and process fluids because particle contamination can disrupt patterning or films and reduce yield.
