CLOSED-LOOP CONTROL FOR IMPROVED POLISHING PAD PROFILES

Номер: US20110256812A1
Принадлежит: APPLIED MATERIALS, INC.

Embodiments described herein use closed-loop control (CLC) of conditioning sweep to enable uniform groove depth removal across the pad, throughout pad life. A sensor integrated into the conditioning arm enables the pad stack thickness to be monitored in-situ and in real time. Feedback from the thickness sensor is used to modify pad conditioner dwell times across the pad surface, correcting for drifts in the pad profile that may arise as the pad and disk age. Pad profile CLC enables uniform reduction in groove depth with continued conditioning, providing longer consumables lifetimes and reduced operating costs.

Closed-loop control of cmp slurry flow

Номер: WO2012005939A3
Принадлежит: Applied Materials, Inc.

Embodiments of the present invention generally relate to methods for chemical mechanical polishing a substrate. The methods generally include measuring the thickness of a polishing pad having grooves or other slurry transport features on a polishing surface. Once the depth of the grooves on the polishing surface is determined, a flow rate of a polishing slurry is adjusted in response to the determined groove depth. A predetermined number of substrates are polished on the polishing surface. The method can then optionally be repeated.
