US6949461B2 - Method for depositing a metal layer on a ...

Disclosed is a method for depositing a metal layer on an interconnect structure for a semiconductor wafer. In the method, a metal conductor is covered by a dielectric layer. The dielectric layer is patterned so as to expose the metal conductor. A liner layer is then deposited into the pattern. The liner layer is then argon sputter etched to remove the liner layer and expose the metal conductor.

How Atomic Layer Deposition Works

Atomic layer deposition The secret to gaining improved control was to split the deposition process into half-reactions, each of which can be well-controlled. The ALD process starts by flooding the reaction chamber with a precursor that coats (or "adsorbs" onto) the exposed surface of the wafer.
