摘要:
A method for etching an etch layer disposed over a substrate and below an antireflective coating (ARC) layer and a patterned organic mask with mask features is provided. The substrate is placed in a process chamber. The ARC layer is opened. An oxide spacer deposition layer is formed. The oxide spacer deposition layer on the organic mask is partially removed, where at least the top portion of the oxide spacer deposition layer is removed. The organic mask and the ARC layer are removed by etching. The etch layer is etched through the sidewalls of the oxide spacer deposition layer. The substrate is removed from the process chamber.

摘要:
A semiconductor substrate processing system includes a processing chamber and a substrate support defined to support a substrate in the processing chamber. The system also includes a plasma chamber defined separate from the processing chamber. The plasma chamber is defined to generate a plasma. The system also includes a plurality of fluid transmission pathways fluidly connecting the plasma chamber to the processing chamber. The plurality of fluid transmission pathways are defined to supply reactive constituents of the plasma from the plasma chamber to the processing chamber. The system further includes an electron injection device for injecting electrons into the processing chamber to control an electron energy distribution within the processing chamber so as to in turn control an ion-to-radical density ratio within the processing chamber. In one embodiment, an electron beam source is defined to transmit an electron beam through the processing chamber above and across the substrate support.

摘要:
A top plate assembly is positioned above and spaced apart from the substrate support, such that a processing region exists between the top plate assembly and the substrate support. The top plate assembly includes a central plasma generation microchamber and a plurality of annular-shaped plasma generation microchambers positioned in a concentric manner about the central plasma generation microchamber. Adjacently positioned ones of the central and annular-shaped plasma generation microchambers are spaced apart from each other so as to form a number of axial exhaust vents therebetween. Each of the central and annular-shaped plasma generation microchambers is defined to generate a corresponding plasma therein and supply reactive constituents of its plasma to the processing region between the top plate assembly and the substrate support.
