摘要： A method for detecting plasma unconfinement in a reaction chamber during a bevel edge cleaning operation is provided. The method initiates with selecting a wavelength associated with expected by products of a bevel edge clean process. The method includes cleaning the bevel edge area of a substrate and monitoring the intensity of the selected wavelengths during the cleaning for deviation from a threshold wavelength intensity. The cleaning is terminated if the deviation from the threshold wavelength intensity exceeds a target deviation.

摘要： A bevel etcher incorporating a vacuum chuck used for cleaning the bevel edge and for reducing the bending curvature of a semiconductor substrate. The bevel etcher includes a vacuum chuck and a plasma generation unit which energizes process gas into a plasma state. The vacuum chuck includes a chuck body and a support ring. The top surface of the chuck body and inner periphery of the support ring form a vacuum region enclosed by the bottom surface of a substrate mounted on the support ring. A vacuum pump evacuates the vacuum region during operation. The vacuum chuck is operative to hold the substrate in place by the pressure difference between the top and bottom surfaces of the substrate. The pressure difference also generates a bending force to reduce the bending curvature of the substrate.

摘要： The various embodiments described in the specification provide improved mechanisms of removal of unwanted deposits on the bevel edge to improve process yield. The embodiments provide apparatus and methods of treating the bevel edge of a copper plated substrate to convert the copper at the bevel edge to a copper compound that can be wet etched with a fluid at a high etch selectivity in comparison to copper. In one embodiment, the wet etch of the copper compound at high selectivity to copper allows the removal of the non-volatile copper at substrate bevel edge in a wet etch processing chamber. The plasma treatment at bevel edge allows the copper at bevel edge to be removed at precise spatial control to about 2 mm or below, such as about 1 mm, about 0.5 mm or about 0.25 mm, to the very edge of substrate. In addition, the apparatus and methods described above for bevel edge copper removal do not have the problems of copper etching fluid being splashed on the device regions to cause defects and thinning of copper films. Therefore, device yield can be greatly improved.

摘要： Methods and systems to optimize wafer placement repeatability in semiconductor manufacturing equipment using a controlled series of wafer movements are provided. In one embodiment, a preliminary station calibration is performed to teach a robot position for each station interfaced to facets of a vacuum transfer module used in semiconductor manufacturing. The method also calibrates the system to obtain compensation parameters that take into account the station where the wafer is to be placed, position of sensors in each facet, and offsets derived from performing extend and retract operations of a robot arm. In another embodiment where the robot includes two arms, the method calibrates the system to compensate for differences derived from using one arm or the other. During manufacturing, the wafers are placed in the different stations using the compensation parameters.

摘要： 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.
