POLISHING APPARATUS AND POLISHING METHOD
The present invention relates to a polishing apparatus and a polishing method for polishing a workpiece, such as a wafer on which a pattern is formed, on a polishing pad, and more particularly, relates to a polishing apparatus and a polishing method for detecting a geometric element of a pattern, such as a pitch. The polishing apparatus includes: a polishing table (3) configured to support a polishing pad (2); a polishing head (1) configured to press a workpiece (W), having a pattern formed therein, against the polishing pad (2) and polish a surface of the workpiece (W), an imaging device (20) disposed in the polishing table (3) and configured to generate an image including at least the pattern of the workpiece (W), and an image analysis system (30) configured determining a geometric element of the pattern of the workpiece (W) based on the image.
BREAK-IN PROCESSING APPARATUS AND BREAK-IN PROCESSING METHOD
A break-in processing apparatus is disclosed, which can reliably perform a break-in process for an elastic membrane without reducing a utilization rate of a polishing apparatus. The break-in processing apparatus includes a stage to which an elastic membrane assembly including a carrier and an elastic membrane attached to the carrier is placed; a break-in determination module facing the elastic membrane placed to the stage; a fluid supply unit configured to supply a pressurized fluid into a pressure chamber formed between the outermost periphery portion of the elastic membrane and the carrier; and a controller configured to control operations of the break-in determination module and the fluid supply unit. The controller determines a completion of a break-in process of the elastic membrane based on a load applied to the break-in determination module by the elastic membrane which is expanded by the pressurized fluid supplied into the pressure chamber.

Imaging for monitoring thickness in a substrate cleaning system
A substrate cleaning system includes a cleaner module to clean a substrate after polishing of the substrate, a drier module to dry the substrate after cleaning by the cleaner module, a substrate support movable along a first axis from a first position in the drier module to a second position outside the drier module, and an in-line metrology station including a line-scan camera positioned to scan the substrate as the substrate is held by the substrate support and the substrate support is between the first position to the second position. The first axis is substantially parallel to a face of the substrate as held in by the substrate support.

MACHINE FOR FINISHING A WORK PIECE, AND HAVING A HIGHLY CONTROLLABLE TREATMENT TOOL
A machine featuring a treatment tool that grinds a surface to a desired profile, imparts a desired roughness to that surface, and removes contamination from the surface, the machine configured to control multiple independent input variables simultaneously, the controllable variables selected from the group consisting of (i) velocity, (ii) rotation, and (iii) dither of the treatment tool, and (iv) pressure of the treatment tool against the surface. The machine can move the treatment tool with six degrees of freedom.

Method and apparatus for polishing a substrate
A polishing method is used for polishing a substrate such as a semiconductor wafer to a flat mirror finish. A method of polishing a substrate by a polishing apparatus includes a polishing table (100) having a polishing surface, a top ring (1) for holding a substrate and pressing the substrate against the polishing surface, and a vertically movable mechanism (24) for moving the top ring (1) in a vertical direction. The top ring (1) is moved to a first height before the substrate is pressed against the polishing surface, and then the top ring (1) is moved to a second height after the substrate is pressed against the polishing surface.
