    摘要: A method is disclosed for depositing a Black Diamond layer in a CVD chamber. Trimethylsilane, O2, and Ar are flowed into the chamber at 300° C. to 400° C. with an O2:Ar:trimethylsilane flow rate ratio that is preferably 1:1.5:6. The resulting low k dielectric layer is formed with a higher deposition rate than when Ar is omitted and has a k value of about 3 that increases only slightly in O2 plasma. A higher density, hardness, and tensile strength are achieved in the Black Diamond layer when Ar is included in the deposition process. The addition of Ar in the deposition maintains film thickness uniformity below 2% for a longer period so that PM cleaning operations are less frequent and affords a lower fluorocarbon plasma etch rate to enable improved trench depth control in a damascene scheme. A lower leakage current and higher breakdown voltage in achieved in the resulting metal interconnect.

    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.
