摘要:We have a method of improving the deposition rate uniformity of the chemicalvapor deposition (CVD) of films when a number of substrates are processed in series,
sequentially in a deposition chamber. The method includes the plasma pre-heating of atleast one processing volume structure within the processing volume which surrounds thesubstrate when the substrate is present in the deposition chamber. We also have adevice-controlled method which adjusts the deposition time for a few substrates at thebeginning of the processing of a number of substrates in series, sequentially in adeposition chamber, so that the deposited film thickness remains essentially constantduring processing of the series of substrates. A combination of these methods into asingle method provides the best overall results in terms of controlling average filmthickness from substrate to substrate.
