Latest Patents

One of Donald E. Brown's notable patents is titled "Method and apparatus for reducing etching erosion in a plasma." This invention provides a method and apparatus designed to minimize wall erosion in a plasma containment tube, such as a quartz plasma tube used in microwave-induced plasma reaction processes for etching semiconductor wafers. The patent introduces a pure benign gas, argon (Ar), into the upstream section of the tube, where microwave energy creates a plasma. This activated benign gas flows downstream through a flange made of quartz, which is seated on o-rings inside a water-cooled metal flange. The design ensures that the sealing o-rings are cooled and protected from the ultraviolet light generated by the plasma. The corrosive etchant gas, sulfur hexafluoride (SF₆), is introduced into the downstream section of the tube, where it is activated by the benign gas. This innovative configuration effectively contains the etchant gas, minimizing etching erosion in both the upstream and downstream sections of the tube.
