    摘要: A method and system for pad conditioning in an electrochemical mechanical planarization (eCMP) tool is disclosed. A polishing pad having a pad electrode is placed onto a platen of the eCMP tool. A conditioning disk, having a second electrode is placed on the polishing pad, such that the pad electrode and conditioning disk form an electrode pair. An electric potential is established between the conditioning disk and the pad electrode. This causes debris from the polishing pad to become ionized, and attracted to the conditioning disk. The conditioning disk is then removed from the eCMP tool, allowing the eCMP tool to resume operation on normal semiconductor wafers.

    摘要: A method for integrating cap liner formation in back-end-of-line (BEOL) processing of a semiconductor device includes forming a trench structure within an insulating layer of the semiconductor device, depositing a first liner material over a top surface of the insulating layer, including sidewall and bottom surfaces of the trench, and partially filling the trench with a wiring metal material to a height corresponding to a final intended line height. A second liner material is over the wiring metal material, and a sacrificial fill material is formed over the second liner material. The sacrificial fill is planarized down to the level of the second liner material over the wiring metal material partially filling the trench, wherein a remaining portion of the second liner material defines a cap liner of the wiring metal.
