摘要： A method for forming features in an etch layer in an etch stack with an etch mask over the etch layer, wherein the etch mask has etch mask features with sidewalls, where the etch mask features have a first critical dimension, is provided. A cyclical critical dimension reduction is performed to form deposition layer features with a second critical dimension, which is less than the first critical dimension. Each cycle, comprises a depositing phase for depositing a deposition layer over the exposed surfaces, including the vertical sidewalls, of the etch mask features and an etching phase for etching back the deposition layer leaving a selective deposition on the vertical sidewalls. Features are etched into the etch layer, wherein the etch layer features have a third critical dimension, which is less than the first critical dimension.

摘要： A method for controlling a plasma etch process while etching a layer stack having a first layer disposed above an end-point generating layer is disclosed. Method includes etching through first layer and at least partially through end-point generating layer while monitoring an absorption rate of a light beam traversing an interior portion of the plasma processing chamber, wherein the end-point generating layer is selected from material that produces a detectable change in absorption rate when etched. The end-point generating layer is characterized by at least one of a first characteristic and a second characteristic. The first characteristic is an insufficient thickness to function as an etch stop layer, and the second characteristic is an insufficient selectivity to etchants employed to etch through the first layer to function as the etch stop layer. The method additionally includes generating an end-point signal upon detecting the detectable change.

摘要： A method and apparatus for performing a dielectric etch, etch mask stripping, and etch chamber clean. A wafer is placed in an etch chamber. A dielectric etch is performed on the wafer using an in situ plasma generated by an in situ plasma device in the etch chamber. The etch mask is stripped using a remote plasma generated in a remote plasma device connected to the etch chamber. The wafer is removed from the etch chamber and either the in situ plasma or the remote plasma may be used to clean the etch chamber. In etch chambers that do not use confinement rings, a heater may be used to heat the etch chamber wall to provide improved cleaning.

摘要： Methods and apparatus for cleaning wafer surfaces are provided, especially for cleaning surfaces of patterned wafers. The cleaning apparatus includes a cleaning head with channels on the surface facing the patterned wafer, which has a predominant pattern. Cleaning material flowing the channels exerts a shear force on the surface of a patterned wafer, which is oriented in a specific direction to the cleaning head. The shear force and the specific orientation between the patterned wafer and the cleaning head improve the removal efficiency of the surface contaminants.
