摘要:
The present invention relates to a device that supplies electricity to a substrate. In one embodiment, the device includes multiple contacts, a current sensor, and a current regulator. The current sensor is attached to each of the plurality of contacts to sense their electric current. A current regulator controls current applied to each of the multiple contacts in response to the current sensor. In another embodiment, a compliant ridge is formed about the periphery of each contact to seal the contact from undesired chemicals.

An apparatus and associated method for securing a wafer to a SRD spider, the SRD spider has a plurality of spider arms. The apparatus includes a plurality of spaced surfaces disposed on a distal end of one of the spider arms, each of the surfaces being spaced perpendicularly from the longitudinal axis of the spider arm. In one aspect, the two surfaces are positioned to limit production of a wedging force between that spaced surface and the wafer. In one embodiment, a post at least partially defines each one of the plurality of spaced surfaces.

Embodiments of the invention provide a spin rinse dry (SRD) chamber for a semiconductor processing system. The SRD chamber includes a selectively rotatable substrate support member having an upper substrate receiving surface formed thereon, and a selectively rotatable shield member positioned above the upper substrate receiving surface, the rotatable shield member having a substantially planar lower surface that may be selectively positioned proximate the upper substrate. Embodiments of the invention further provide a method for rinsing semiconductor substrates, including the steps of positioning the substrate on a substrate support member, positioning a shield member having a substantially planar lower surface in a processing position above the substrate such that the substantially planar lower surface is in parallel orientation with an upper surface of the substrate, and flowing a fluid solution into a processing region defined by the upper surface of the substrate and the substantially planar lower surface via a fluid aperture in the substantially planar lower surface.
摘要:
An apparatus and a method of depositing a catalytic layer comprising at least one metal selected from the group consisting of noble metals, semi-noble metals, alloys thereof, and combinations thereof in sub-micron features formed on a substrate. Examples of noble metals include palladium and platinum. Examples of semi-noble metals include cobalt, nickel, and tungsten. The catalytic layer may be deposited by electroless deposition, electroplating, or chemical vapor deposition. In one embodiment, the catalytic layer may be deposited in the feature to act as a barrier layer to a subsequently deposited conductive material. In another embodiment, the catalytic layer may be deposited over a barrier layer. In yet another embodiment, the catalytic layer may be deposited over a seed layer deposited over the barrier layer to act as a “patch” of any discontinuities in the seed layer. Once the catalytic layer has been deposited, a conductive material, such as copper, may be deposited over the catalytic layer. In one embodiment, the conductive material is deposited over the catalytic layer by electroless deposition. In another embodiment, the conductive material is deposited over the catalytic layer by electroless deposition followed by electroplating or followed by chemical vapor deposition. In still another embodiment, the conductive material is deposited over the catalytic layer by electroplating or by chemical vapor deposition.

A non-contact apparatus and method for removing a metal layer from a substrate are provided. The apparatus includes a rotatable anode substrate support member configured to support a substrate in a face-up position and to electrically contact the substrate positioned thereon. A pivotally mounted cathode fluid dispensing nozzle assembly positioned above the anode substrate support member is also provided. A power supply in electrical communication with the anode substrate support member and the cathode fluid dispensing nozzle is provided, and a system controller configured to regulate at least one of a rate of rotation of the anode substrate support member, a radial position of the cathode fluid dispensing nozzle, and an output power of the power supply is provided. The method provides for the removal of a metal layer from a substrate by rotating the substrate in a face up position on a rotatable substrate support member. A cathode fluid dispensing nozzle is positioned over a central portion of the substrate and a metal removing solution is dispensed from the cathode fluid dispensing nozzle onto the central portion of the substrate. An electrical bias is applied between the substrate and the cathode fluid dispensing nozzle, which operates to deplate the metal layer below the fluid dispensing nozzle.
