Abstract: Described herein are multi-layered windows for use in chemical-mechanical planarization (CMP) systems and CMP processes. The multi-layered windows of the present disclosure include a transparent structural layer and a hydrophilic surfactant applied to at least a portion of at least one surface of the transparent structural layer. Such multi-layered windows may be in the polishing pad, the platen, or both.
