CHEMICAL-MECHANICAL PLANARIZATION PAD HAVING END POINT DETECTION WINDOW

摘要

A chemical mechanical polishing pad. The pad includes a surface and a polymer matrix capable of transmitting at least a portion of incident radiation. In addition, at least one embedded structure in the polymer matrix, including a portion of the pad where the embedded structure is not present, and a window integral to the pad defined by the portion of the pad where the embedded structure is not present.
