Abstract:
A plasma enhanced chemical vapor deposition process sequentially comprising:in a first plurality of discrete depositions, plasma enhanced chemical vapor depositing material upon a plurality of semiconductor substrates within a chamber of a plasma enhanced chemical vapor deposition reactor; disassembling the reactor at least by separating an electrically conductive RF powered showerhead support electrode of the reactor and an electrically conductive gas distributing showerhead of the reactor from one another; sandwiching an electrically conductive material between the electrically conductive RF powered showerhead support electrode and the electrically conductive gas distributing showerhead during a reassembly of the reactor at least including connecting the electrically conductive RF powered showerhead support electrode and an electrically conductive gas distributing showerhead together; and in a second plurality of discrete depositions, plasma enhanced chemical vapor depositing material upon a plurality of semiconductor substrates within the chamber of the plasma enhanced chemical vapor deposition reactor.
