    摘要: A method of forming an opening in a stack of insulator layers featuring an underlying etch stop layer comprised of a tri-layer insulator composite, has been developed. The tri-layer insulator composite comprised of a bottom silicon rich, silicon oxide layer and a top silicon nitride layer, is first formed on a conductive region of a semiconductor substrate. After deposition of overlying insulator layers a photoresist shape is used as a etch mask to allow the desired contact or via hole shape to be defined in the overlying insulator layers via a first phase of an anisotropic dry etch procedure, with the first phase of the dry etching procedure terminating at the top surface of the silicon nitride layer. An over etch procedure used to insure complete removal of overlying insulator layer from the surface of the tri-layer insulator composite, is next performed as a second phase of the anisotropic dry etch procedure. The high etch rate ratio of insulator layer to silicon nitride allows the over etch cycle to be successfully accomplished without risk to underlying materials. A third phase of the anisotropic dry etch procedure selectively removes the silicon nitride layer and subsequently selectively removes the silicon rich, silicon oxide layer without damage to the now exposed conductive region, resulting in definition of the desired contact or via hole openings in the stack of insulator layers.

    摘要: A method for forming a composite barrier layer that also functions as an etch stop in a damascene process is disclosed. A SiC layer is deposited on a substrate in a CVD process chamber followed by deposition of a silicon nitride layer to complete the composite barrier layer. The SiC layer exhibits excellent adhesion to a copper layer in the substrate and is formed by a method that avoids reactive Si+4 species and thereby prevents CuSiX formation. The silicon nitride layer thickness is sufficient to provide superior barrier capability to metal ions but is kept as thin as possible to minimize the dielectric constant of the composite barrier layer. The composite barrier layer provides excellent resistance to copper oxidation during oxygen ashing steps and enables a copper layer to be fabricated with a lower leakage current than when a conventional silicon nitride barrier layer is employed.
