摘要:
A high density plasma chemical vapor deposition process including exciting gas mixture to create a plasma including ions, and directing the plasma into a dense region above the upper surface of the semiconductor wafer, heating the wafer using an additional heat source, and allowing a material from the plasma to deposit onto the semiconductor wafer.

摘要:
A method for etching a dielectric material in a semiconductor device is disclosed. After providing a conductive region, a dielectric layer is formed over the conductive region. A dielectric antireflective coating (DARC) layer is further formed on the dielectric layer. Then, a moisture-removal step is performed that removes moisture from the DARC layer and from an interface region between the dielectric and the DARC layer. A masking pattern is transferred into the DARC layer and the dielectric layer.
