Abstract
The present invention relates to an apparatus and method for depositing a film on a wafer. A reactor for depositing a film on a surface of a wafer comprises a processing chamber having an electrode, a ceramic wafer support supporting the wafer and separated from the electrode by a distance of between 230 and 240 millimeters, a gas inlet supplying gas reactants, and a radio frequency inlet supplying radio frequency energy. The reactor further comprises a heating chamber having at least one heat source which heats the wafer. A method for depositing a film on a surface of a semiconductor wafer comprises providing a processing chamber having a ceramic wafer support supporting the wafer and an electrode, separating the electrode from the ceramic wafer support by a distance of between 230 and 240 millimeters, supplying radio frequency energy into the processing chamber, supplying gas reactants into the processing chamber, and heating the wafer.
