    摘要: Systems and methods include introducing a semiconductor wafer into a process chamber. An etching chemistry is injected into the process chamber to etch a patterned layer and to release free-standing nanostructures on the semiconductor wafer. The etching chemistry includes a supercritical or liquid carbon dioxide fluid and an etching solution. The semiconductor wafer is rinsed by flooding a supercritical or liquid carbon dioxide fluid into the process chamber. The semiconductor wafer is dried by venting out supercritical or liquid carbon dioxide fluid from the process chamber.

    摘要: A method for manufacturing contact structures for DRAM semiconductor memories is disclosed. In one embodiment, contact openings are formed in a support area after execution of high-temperature processes for activating doping agents and repairing crystal defects. A low contact resistance between a conductive contact opening filling and an adjacent semiconductor substrate is achieved by forming a cobalt silicide or nickel silicide.
