摘要: This invention provides a high throughput PECVD process for depositing TEOS films in a multi-station sequential deposition chamber. The methods significantly reduce the number of particles in the TEOS films, thereby eliminating or minimizing small bin defects. The methods of the invention involve dedicating a first station for temperature soak while flowing purge gas. Stopping the flow of reactant gas and flowing the purge gas for station 1 eliminates TEOS condensation on a cold wafer surface and significantly reduces the number of defects in the film, particularly for short temperature soaks.
