Abstract
A method and apparatus for forming a semiconductor device. A semiconductor substrate is implanted with dopants. The substrate is subjected to a cleaning process employing electrically neutral nitrogen and fluorine radicals to produce an oxygen-free surface having dangling bonds. Before any further exposure to oxidizing gases, the substrate is annealed by thermal treatment to activate and distribute the dopants. A gate oxide layer is formed over the annealed surface. The apparatus performs all such treatments without breaking vacuum.
