Fine Particles on Semiconductor Surfaces: Sources, Removal and Impact on the Semiconductor Industry
The impact of fine particles and organic contamination on device yield is very serious. We have investigated several technologies in this area. They include: 1) Application of thermophoresis for the prevention of surface contamination. 2) The use of electrets for collection of particles that might otherwise settle on surfaces. 3) The use of dry ice snow as a cleaning medium for the removal of particulates and organic contamination.
