    摘要: 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. The pulsed application of the TCP power source is configured to etch through the dielectric layer to at least one contact via hole or open area while substantially reducing damage to the transistor gate oxides of the transistor devices.

    摘要: 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.

    摘要: 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. The wafer stack includes a substrate, a polysilicon layer disposed above the substrate, a nitride layer disposed above said polysilicon layer and the oxide layer disposed above the nitride layer. The method for etching includes etching through the oxide layer of the layer stack with a chemistry and a set of process parameters. The chemistry essentially includes C.sub.2 HF.sub.5 and CH.sub.2 F.sub.2 and the set of process parameters facilitate etching through the oxide layer without creating a spiked etch and etching the oxide layer through to the substrate without substantially damaging the nitride layer.

    摘要: A plasma etch reactor comprising a remote source of plasma mounted on a vacuum processing chamber has a large permanent magnet ring around the area of the chamber where the plasma enters, magnetically oriented so that magnetic field lines are removed from said plasma in the processing chamber, and two or more pairs of magnet rings mounted around said chamber to form a series of magnetic cusps about the wall of said chamber, to thereby inhibit plasma electrons from striking the wall of said chamber. A substrate entry port can be fitted between the magnet rings, allowing automatic ingress and egress of said substrates with maximum efficiency.
