    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. In some embodiments, the facility analyzes a profile of the seed layer applied to a workpiece, and determines and communicates to a material deposition tool a set of control parameters designed to deposit material on the workpiece in a manner that compensates for deficiencies in the seed layer.

    摘要: In an electroplating process, electric current is applied to two or more electrodes, with the current varying over time according to a multi-variable function. The multi-variable current function is integrated over time, for each electrode, to determine a net plating charge delivered. A plating profile of a plated-on layer of material is compared to a target plating profile. Deviations between the actual plating profile and the target plating profile are identified and used to determine new net plating charges for each electrode. One or more variables of the multi-variable function is changed to provide a new multi-variable function. The new net plating charges are distributed according to the new multi-variable current function, and are used to electroplate a layer of material on a second substrate.

    摘要: In an electro processor for plating semiconductor wafers and similar substrates, a contact ring has a plurality of spaced apart contact fingers. A shield at least partially overlies the contact fingers. The shield changes the electric field around the outer edge of the workpiece and the contact fingers, which reduces or eliminates the negative aspects of using high thief electrode currents and seed layer deplating. The shield may be provided in the form of an annular ring substantially completely overlying and covering, and optionally touching the contact fingers.

    摘要: A substrate or semiconductor wafer processing apparatus has an agitator plate adjacent to an upper end of a process vessel. A workpiece holder holds a workpiece in the vessel at a processing position above the agitator plate. A vertical actuator assembly supporting the agitator plate oscillates the agitator plate vertically. The agitator plate may also rotate while oscillating vertically. In one design, the agitator plate has a spiral vane and a spiral slot. In a related metal plating apparatus, electrodes and a dielectric field shaping unit are in the vessel, below the agitator plate, and a shield ring is adjacent to the upper end of the vessel, above the agitator plate.

    摘要: An apparatus for thermally processing a microelectronic workpiece is set forth. The apparatus comprises a first assembly and a second assembly, disposed opposite one another, with an actuator disposed to provide relative movement between the first assembly and second assembly. More particularly, the actuator provides relative movement between at least a loading position in which the first assembly is in a state for loading or unloading of the microelectronic workpiece, and a thermal processing position in which the first assembly and second assembly are proximate one another and form a thermal processing chamber. A thermal transfer unit is disposed in the second assembly and has a workpiece support surface that is heated and cooled in a controlled manner. As the first assembly and second assembly are driven to the thermal processing position by the actuator, an arrangement of elements bring a surface of the microelectronic workpiece into direct physical contact with the workpiece support surface of the thermal transfer unit. In a preferred embodiment, the thermal transfer unit is comprised of a low thermal mass heater and a high thermal mass cooler disposed to controllably cool the low thermal mass heater.
