摘要:
A process for metallization of a workpiece, such as a semiconductor workpiece. In an embodiment, an alkaline electrolytic copper bath is used to electroplate copper onto a seed layer, electroplate copper directly onto a barrier layer material, or enhance an ultra-thin copper seed layer which has been deposited on the barrier layer using a deposition process such as PVD. The resulting copper layer provides an excellent conformal copper coating that fills trenches, vias, and other microstructures in the workpiece. When used for seed layer enhancement, the resulting copper seed layer provide an excellent conformal copper coating that allows the microstructures to be filled with a copper layer having good uniformity using electrochemical deposition techniques. Further, copper layers that are electroplated in the disclosed manner exhibit low sheet resistance and are readily annealed at low temperatures.

A processing apparatus for processing a microelectronic workpiece includes a metrology unit and a control, signal-connected to the metrology unit. The control can modify a process recipe or a process sequence of the processing apparatus based on a feed forward or a feed back signal from the metrology unit. A seed layer deposition tool, a process layer electrochemical deposition tool, and a chemical mechanical polishing tool, arranged for sequential processing of a workpiece, can be controlled as an integrated system using one or more metrology units. A metrology unit can be located at each tool to measure workpiece parameters. Each of the metrology units can be used as a feed forward control and/or a feed back control at each of the tools.

A thermal processor may include a cooling jacket positionable around a process chamber within a process vessel or jar. A heater can move into a position substantially between the process chamber vessel and the cooling jacket. A holder having multiple workpiece holding positions is provided for holding a batch or workpieces or wafers. The process chamber vessel is moveable to a position where it substantially encloses the holder, so that wafers in the holder may be processed in a controlled environment. A cooling shroud may be provided to absorb heat from the heater before or after thermal processing. The thermal processor is compact and thermally shielded, and may be used in an automated processing system having other types of processors.

摘要:
A facility for selecting and refining electrical parameters for processing a microelectronic workpiece in a processing chamber is described. The facility initially configures the electrical parameters in accordance with either a mathematical model of the processing chamber or experimental data derived from operating the actual processing chamber. After a workpiece is processed with the initial parameter configuration, the results are measured and a sensitivity matrix based upon the mathematical model of the processing chamber is used to select new parameters that correct for any deficiencies measured in the processing of the first workpiece. These parameters are then used in processing a second workpiece, which may be similarly measured, and the results used to further refine the parameters.
摘要:
An apparatus and method for processing a microelectronic workpiece at an elevated temperature. In one embodiment, the apparatus includes a workpiece support positioned to engage and support the microelectronic workpiece during operation. The apparatus can further include a heat source having a solid engaging surface positioned to engage a surface of the microelectronic workpiece with at least one of the heat source and the workpiece support being movable relative to the other between a first position with the microelectronic workpiece contacting the engaging surface of the heat source and a second position with the microelectronic workpiece spaced apart from the engaging surface. The heat source is sized to transfer heat to the microelectronic workpiece at a rate sufficient to thermally process a selected material of the microelectronic workpiece when the microelectronic workpiece is engaged with the heat source. A heat sink can be positioned at least proximate to the heat source to cool both the heat source and the microelectronic workpiece.
摘要:
An electrochemical processing apparatus for processing a microelectronic workpiece includes a metrology unit and a control, signal-connected to the metrology unit. An electrochemical deposition unit provides a space to receive said microelectronic workpiece to deposit a subsequent film layer onto a prior layer, wherein a condition signal from the metrology unit influences the process control of the electrochemical deposition unit. The signal can also be used to transfer the microelectronic workpiece to a layer stripping unit, or a layer enhancement unit, or to a non-compliance station. The apparatus is particularly useful in measuring seed layer thickness and adjusting the operating control of a computational fluid dynamic reactor, which electroplates a process layer onto the seed layer.

An electro-processing apparatus includes a rotor in a head, and a contact ring assembly on the rotor. The contact ring assembly may have one or more strips of contact fingers on a ring base, with contact fingers clamped into position on the ring base. The strips may have spaced apart projection openings, with the projections on the ring base extending into or through the projection openings. A shield ring may be attached to the ring base, to clamp the contact fingers in place, and/or to provide an electric field shield over at least part of the contact fingers. The contact fingers may be provided as a plurality of adjoining forks, with substantially each fork including at least two contact fingers.
