摘要： A work piece carrier head can carry a semiconductor wafer during both plating and polishing operations. The carrier head includes a first component secured to a shaft by which the carrier head can be rotated, translated, and moved up and down, a second component connected to the first component and movable by fluid pressure relative to the first component between retracted and extended positions, and a third component connected to the first and second components for up and down movement between wafer loading or unloading and wafer plating or polishing positions. The third carrier head component includes a contact element by which electrical contact with the wafer is provided to permit wafer plating.

摘要： A polishing head for performing chemical-mechanical polishing on a linear polisher has a dual stage wafer carrier assembly that incorporates a removable subcarrier. When in use, a main pressure chamber exerts a downforce on the subcarrier housing, while a separate secondary pressure chamber residing between the subcarrier housing and the subcarrier exerts a slightly different downforce on the subcarrier. Since the second pressure chamber exerts the downforce pressure directly on the subcarrier, the direct pressure application, as well as a more uniform distribution of pressure ensures for an improvement to the uniformity of pressure distribution. Additionally, the easily removal subcarrier allows for faster and easier removal of the subcarrier for cleaning and maintenance, as well as for changing inserts and improving process repeatability.

摘要： The present invention includes a polishing pad or belt secured to a mechanism that allows the pad or belt to move in a reciprocating manner, i.e. in both forward and reverse directions, at high speeds. The constant bidirectional movement of the polishing pad or belt as it polishes the wafer provides superior planarity and uniformity across the wafer surface. When a fresh portion of the pad is required, the pad is moved through a drive system containing rollers, such that the rollers only touch a back side of the pad, thereby minimizing sources of friction other than the wafer that is being polished from the polishing side of the pad, and maximizing the lifetime of the polishing pad.

摘要： The present invention is directed to methods and apparatus for polishing a surface of a semiconductor wafer using a pad or belt moveable in both forward and reverse directions. In both VLSI and ULSI applications, polishing the wafer surface to complete flatness is highly desirable. The forward and reverse movement of the polishing pad or belt provides superior planarity and uniformity to the surface of the wafer. The wafer surface is pressed against the polishing pad or belt as the pad or belt moves in both forward and reverse directions while polishing the wafer surface. During polishing, the wafer is supported by a wafer housing having novel wafer loading and unloading methods.

摘要： A polishing pad dressing method uses a polishing head for polishing a semiconductor wafer. This polishing head includes a housing, a wafer carrier movably mounted to the housing, and a pad dressing element movably mounted to the housing. The wafer carrier forms a wafer-supporting surface, and the dressing element surrounds the wafer-supporting surface. A first fluid actuator is coupled to the dressing element to bias the pad dressing element with respect to the housing, and a second fluid actuator is coupled to the wafer carrier to bias the wafer carrier with respect to the housing. First and second fluid conduits are coupled to the first and second actuators, respectively, such that fluid pressures in the first and second actuators are separately and independently adjustable with respect to one another. Biasing forces on the dressing element can thereby be dynamically adjusted with respect to biasing forces on the carrier during a polishing operation.

摘要： The present invention relates to a containment chamber that is used for carrying out multiple processing steps such as depositing on, polishing, etching, modifying, rinsing, cleaning, and drying a surface on the workpiece. In one example of the present invention, the chamber is used to electro chemically mechanically deposit a conductive material on a semiconductor wafer. The same containment chamber can then be used to rinse and clean the same wafer. As a result, the present invention eliminates the need for separate processing stations for depositing the conductive material and cleaning the wafer. Thus, with the present invention, costs and physical space are reduced while providing an efficient apparatus and method for carrying out multiple processes on the wafer surface using a containment chamber.
