Abstract:
An antenna arrangement for generating an electric field inside a process chamber through a window. Generally, the antenna arrangement comprises an outer loop, comprising a first outer loop turn disposed around an antenna axis, an inner loop, comprising a first inner loop turn disposed around the antenna axis, wherein the inner loop is closer to the antenna axis than the outer loop is to the antenna axis in each azimuthal direction, and a radial connector radially electrically connecting the outer loop to the inner loop, wherein the radial connector is placed a large distance from the window.
Abstract:
A method is provided for processing a wafer used in fabricating semiconductor devices. The method can comprise forming high-aspect ratio features on the wafer, which is followed by wet processing and drying. During drying, pattern collapse can occur. This pattern collapse can be repaired to allow for additional processing of the wafer. In some instance, pattern collapse can be repaired via etching where the etching breaks bonds that can have formed during pattern collapse.

Abstract:
An apparatus, system and method for cleaning a substrate edge include a bristle brush unit that cleans bevel polymers deposited on substrate edges using frictional contact in the presence of cleaning chemistry. The bristle brush unit is made up of a plurality of outwardly extending vanes and is mounted on a rotating shaft. An abrasive material is distributed throughout and within the outwardly extending vanes of the bristle brush unit to provide the frictional contact. The bristle brush unit cleans the edge of the substrate by allowing frictional contact of the plurality of abrasive particles with the edge of the substrate in the presence of fluids, such as cleaning chemistry, to cut, rip and tear the bevel polymer from the edge of the substrate.

Abstract:
A method for etching a feature in a low-k dielectric layer through a photoresist etch mask over a substrate. A gas-modulated cyclic stripping process is performed for more than three cycles for stripping a single photoresist mask. Each cycle of the gas-modulated cyclic stripping process comprises performing a protective layer formation phase and a stripping phase. The protective layer forming phase uses first gas chemistry with a deposition gas chemistry, wherein the protective layer forming phase is performed in about 0.005 to 10 seconds for each cycle. The stripping phase for stripping the photoresist mask uses a second gas chemistry using a stripping gas chemistry, where the first gas chemistry is different than the second gas chemistry, wherein the etching phase is performed in about 0.005 to 10 seconds for each cycle.
