Compositions and methods for processing a substrate having a conductive material layer disposed thereon are provided. In one embodiment, a composition for processing a substrate having a conductive material layer disposed thereon is provided which composition includes an acid based electrolyte, a chelating agent, a corrosion inhibitor, a passivating polymeric material, a pH adjusting agent, a solvent, and a pH between about 3 and about 10.

Embodiments of the invention provide a method for conditioning contacts of an electrochemical metal plating system. The method includes deplating the contacts by supplying a reversed biased energy and monitoring electrical measurements of the plating system in real-time such that the endpoint of a deplating process can be determined. In different embodiments, the method includes the use of a constant current or voltage, variable current or voltage, or combinations thereof for conditioning the contacts.

A failure resistant electrostatic chuck 20 for holding a substrate 35 during processing of the substrate 35 comprises one or more electrodes 25 covered by an insulator 30, the electrodes 25 capable of electrostatically holding a substrate 35 when a voltage is applied thereto. An electrical power bus 40 comprises one or more output terminals 45 that conduct voltage to the electrodes 25. The fuses 50 are positioned in hollow cavities 55 in the insulator 30, and electrically connect the electrodes 25 in series to the output terminals 45 of the power bus 40. Each fuse 50 can electrically disconnect an electrode 25 from an output terminal 45 when the insulator 30 covering the electrode 25 punctures and exposes the electrode 25 to a plasma process environment thereby causing a plasma current discharge to flow through the fuse 50.

A sliding mechanism comprises a main plate, a sliding plate, a sliding enabling member and a biasing assembly. The sliding enabling member is coupled between the sliding plate and the main plate so the sliding plate slidably engages with the main plate. The biasing assembly is coupled between the sliding plate and the main plate. When the sliding plate is slid from a closed position to an intermediate position, the biasing assembly is distorted to exert a force on the sliding plate and the main plate, causing the sliding plate to automatically slide toward an open position once the sliding plate passes the intermediate position.

Polishing compositions and methods for removing conductive materials from a substrate surface are provided. The method includes providing a substrate comprising dielectric feature definitions, a barrier material disposed in the feature definitions, and a bulk conductive material disposed on the barrier material in an amount sufficient to fill feature definitions; polishing the substrate to substantially remove the bulk conductive material; polishing a residual conductive material to expose feature definitions, comprising: applying a first voltage for a first time period, wherein the first voltage is less than the critical voltage; and applying a second voltage for a second time period, wherein the second voltage is greater than the critical voltage.

摘要:
Polishing compositions and methods for removing barrier materials from a substrate surface are provided. In one aspect, a composition is provided for removing at least a barrier material from a substrate surface including an acid based electrolyte system, one or more chelating agents, one or more pH adjusting agents to provide a pH between about 3 and about 11, and a solvent. The composition may be used in an electrochemical mechanical planarization process. The polishing compositions and methods described herein improve the effective removal rate of barrier materials from the substrate surface with a reduction in planarization type defects.
