    Abstract: A substrate processing apparatus includes a first mounting unit, a second mounting unit and an adjusting unit. The first mounting unit is configured to mount thereon a target substrate to be processed that is a plasma processing target. The second mounting unit is disposed to surround the first mounting unit to mount thereon a focus ring. The adjusting unit is configured to adjust a height of a peripheral portion of the target substrate with respect to a height of a central portion of the target substrate in response to consumption of the focus ring.

    Abstract: In a method of cleaning a bottom of a via hole, a copper oxide on a surface of an underlying Cu wiring exposed at the bottom of the via hole is removed before forming a Cu wiring in a trench and the via hole extended between the trench and the underlying Cu wiring. The trench and the via hole are formed in a predetermined pattern in an interlayer insulating film of a substrate. Reducing species containing a metal in a state capable of reducing the copper oxide is supplied to the bottom of the via hole. The metal has a higher oxidation tendency than Cu and an oxide of the metal has a lower electrical resistance than the copper oxide. The copper oxide is removed by reducing the copper oxide and the oxide of the metal is generated through a reaction between the metal in the reducing species and the copper oxide.

    Abstract translation: 在清洗通孔的底部的方法中,在形成沟槽中的Cu布线之前去除在通孔的底部露出的下面的Cu布线的表面上的氧化铜,并且通孔延伸在沟槽和 底层Cu布线。 在基板的层间绝缘膜中以规定的图案形成沟槽和通孔。 将能够还原氧化铜的状态的金属还原的物质供给到通孔的底部。 金属具有比Cu更高的氧化倾向,并且金属的氧化物具有比氧化铜更低的电阻。 通过还原氧化铜除去氧化铜,通过还原物质中的金属与氧化铜之间的反应产生金属的氧化物。
