    摘要: The present invention provides a method and apparatus that plates/deposits a conductive material on a semiconductor substrate and then polishes the same substrate. This is achieved by providing multiple chambers in a single apparatus, where one chamber can be used for plating/depositing the conductive material and another chamber can be used for polishing the semiconductor substrate. The plating/depositing process can be performed using brush plating or electro chemical mechanical deposition and the polishing process can be performed using electropolishing or chemical mechanical polishing. The present invention further provides a method and apparatus for intermittently applying the conductive material to the semiconductor substrate and also intermittently polishing the substrate when such conductive material is not being applied to the substrate. Furthermore, the present invention provides a method and apparatus that plates/deposits and/or polishes a conductive material and improves the electrolyte mass transfer properties on a substrate using a novel anode assembly.

    摘要: An anode assembly by which a solution can be supplied to a surface of a semiconductor substrate includes a housing defining an internal housing volume into which the solution can flow. A closure is provided for the internal housing volume, and the solution can be discharged from the internal housing volume through the closure towards the surface of the semiconductor substrate. A filter divides the internal housing volume into a first chamber and a second chamber located between the first chamber and the closure. During supply of the solution to the surface, a flow of the solution into the second chamber occurs at a higher rate than a flow of the solution into the first chamber, and the flows are blended in the second chamber.

    摘要: A coater having a controllable pressurized process chamber for applying photoresist to a wafer is provided. The controllable pressurized process chamber reduces the evaporation of solvent in the photoresist during a spin-on process step. Reducing premature curing of the photoresist results in improved uniform planarization of the photoresist layer. Contaminants in the photoresist are also reduced by having an environmentally controllable process chamber. A housing having a upper and lower section forms a process chamber surrounding a wafer chuck. The upper housing section includes a solvent vapor opening for introducing pressurized solvent vapor into the process chamber and the lower housing section includes an exhaust opening. The upper housing section also includes an opening for introducing photoresist onto a wafer. A control device is coupled to the exhaust opening and a vacuum device for controlling the pressure in the process chamber. A sealed recycling photoresist container and recycling apparatus is also coupled to the exhaust opening to store unused photoresist. The unused photoresist may be used in subsequent spin-on process steps, thereby reducing processing costs.

    摘要: The present invention provides a process for electropolishing a conductive surface of a semiconductor wafer. During the process, a contact electrode in a contact solution contacts a contact region on surface of the conductive layer with the contact solution. Further, during the process a process electrode in a process solution contacts a process region on the conductive surface with the process solution while applying an electrical potential between the contact electrode and the process electrode to electropolish the surface of the conductive layer of the process region.

    摘要: Substantially uniform deposition of conductive material on a surface of a substrate, which substrate includes a semiconductor wafer, from an electrolyte containing the conductive material can be provided by way of a particular device which includes first and second conductive elements. The first conductive element can have multiple electrical contacts, of identical or different configurations, or may be in the form of a conductive pad, and can contact or otherwise electrically interconnect with the substrate surface over substantially all of the substrate surface. Upon application of a potential between the first and second conductive elements while the electrolyte makes physical contact with the substrate surface and the second conductive element, the conductive material is deposited on the substrate surface. It is possible to reverse the polarity of the voltage applied between the anode and the cathode so that electro-etching of deposited conductive material can be performed.
