    摘要: A processing chamber successfully removes hardened photoresist via direct infrared radiation onto the wafer, in the presence of an acid such as sulfuric acid, optionally along with an oxidizer such as hydrogen peroxide. The processing chamber includes a fixture for holding and optionally rotating the wafer. An infrared irradiating assembly has infrared lamps outside of the processing chamber positioned to radiate infrared light into the processing chamber. The infrared lamps may be arranged to irradiate substantially the entire surface of a wafer on the rotor. A cooling assembly can be associated with the infrared radiating assembly to provide a quick cool down and avoid over-processing. Photoresist is removed using small amounts of chemical solutions.

    摘要: Methods and etchant solutions for etching silicon nitride on a workpiece are provided. One method generally includes exposing the workpiece to a chemistry mixture including phosphoric acid and a diluent, wherein the chemistry mixture has a water content of less than 10% by volume, and heating at least one of the workpiece and the chemistry mixture to a process temperature to etch silicon nitride from the workpiece.
