Abstract: Broadly speaking, a method and an apparatus are provided for depositing a material on a semiconductor wafer (“wafer”). More specifically, the method and apparatus provide for selective heating of a surface of the wafer exposed to an electroless plating solution. The selective heating is provided by applying radiant energy to the wafer surface. The selective heating of the wafer surface causes a temperature increase at an interface between the wafer surface and the electroless plating solution. The temperature increase at the interface in turn causes a plating reaction to occur at the wafer surface. Thus, material is deposited on the wafer surface through an electroless plating reaction that is initiated and controlled by varying the temperature of the wafer surface using an appropriately defined radiant energy source.

Abstract: Disclosed are methods and systems for etching dielectric layers in a high density plasma etcher. A method includes providing a wafer having a photoresist mask over a dielectric layer in order to define at least one contact via hole or open area that is electrically interconnected down to the silicon substrate of the wafer. The method then proceeds to inserting the wafer into the high density plasma etcher and pulsed application a TCP power source of the high density plasma etcher. The pulsed application includes ascertaining a desired etch performance characteristic, which includes photoresist selectivity and etch rate which is associated with a continuous wave application of the TCP source. Then, selecting a duty cycle of the pulsed application of the TCP source and scaling a peak power of the pulsed application of the TCP source in order to match a cycle-averaged power that would be delivered by the continuous wave application of the TCP source.

Abstract: In a plasma processing system for processing substrates such as semiconductor wafers, deposition of polymer in an area between a focus ring and an electrostatic chuck in a plasma processing chamber is achieved by providing a clearance gas in a gap between the chuck and the focus ring. A series of channels delivers the clearance gas to the annular gap between the outer surface of the substrate support and the inner surface of the focus ring surrounding the substrate support. The clearance gas supplied to the annular gap is preferably a gas such as helium which will not affect the wafer processing operation. In the case of plasma etching, the clearance gas is supplied at a flow rate which is sufficient to block the migration of process gas and volative byproducts thereof into the annular gap without adversely affecting edge etch performance.

Abstract: In a plasma processing chamber, a method for etching through a selected portion of an oxide layer of a wafer's layer stack to create a self-aligned contact opening is described.

Abstract: A plasma processing chamber includes a substrate holder and a dielectric member such as a dielectric window or gas distribution plate having an interior surface facing the substrate holder, the interior surface being maintained below a threshold temperature to minimize process drift during processing of substrates. The chamber can include an antenna which inductively couples RF energy through the dielectric member to energize process gas into a plasma state. The antenna can include a channel through which a temperature controlling fluid, which has been cooled by a closed circuit temperature controller, is passed. The control of the temperature of the interior surface minimizes process drift and degradation of the quality of the processed substrates during sequential batch processing of substrates such as during oxide etching of semiconductor wafers.
