    摘要: An endpoint detection method includes processing an outer surface of a substrate, directing an incident light beam through a window in an opaque metal body onto the surface being processed, receiving at a detector a reflected light beam from the substrate and generating a signal from the detector, and generating a signal based on the reflected light beam received at the detector, and detecting a processing endpoint. The signal is a time-varying cyclic signal that varies as the thickness of the layer varies over time, and detecting the processing endpoint includes detecting that a portion of a cycle of the cyclic signal has passed, the portion being less than a full cycle of the cyclic signal.

    摘要: A system method and apparatus to monitor a frictional coefficient of a substrate undergoing polishing is described. A polishing pad assembly includes a polishing layer including a polishing surface, and a substrate contacting member flexibly coupled to the polishing layer having a top surface to contact an exposed surface of a substrate. At least a portion of the top surface is substantially coplanar with the polishing surface. A sensor is provided to measure a lateral displacement of the substrate contacting member. Some embodiments may provide accurate endpoint detection during chemical mechanical polishing to indicate the exposure of an underlying layer.

    摘要: A polishing pad assembly for a chemical mechanical polishing apparatus includes a polishing pad having a polishing surface and a surface opposite the polishing surface for attachment to a platen, and a solid light-transmissive window formed in the polishing pad. The light-transmissive window is more transmissive to light than the polishing pad. The light-transmissive window has a light-diffusing bottom surface.

    摘要: A CMP station can be closed loop controlled by using data obtained by an inline metrology station from a first polished wafer to affect the processing of subsequent polished wafers. The first wafer is polished and measured by the inline metrology station. The metrology station measures at various points the array dielectric thickness, field dielectric thickness, barrier residue thickness and metal residue thickness. The data is then inputted into an algorithm and polishing parameter outputs are calculated. The outputs are sent to the CMP station and used to supplement or replace the previous polishing parameters. Subsequent wafers are polished on the CMP station using the revised polishing parameters.
