Abstract This article discusses the mechanisms of particle deposition onto cleanroom surfaces.  The main mechanism for particles above 0.5 µm is gravitational settling.  Turbulent deposition and electronstatic attraction can also occur at all particle sizes, and for particles below 0.5 µm Brownian diffusion is important.
