摘要: A semiconductor interconnect structure and method providing an embedded barrier layer to prevent damage to the dielectric material during or after Chemical Mechanical Polishing. The method employs a combination of an embedded film, etchback, using either selective CoWP or a conformal cap such as a SiCNH film, to protect the dielectric material from the CMP process as well as subsequent etch, clean and deposition steps of the next interconnect level.

摘要: A method and structure for a composite stud contact interface with a decreased contact resistance and improved reliability. A selective dry etch is used which comprises a fluorine containing gas. The contact resistance is reduced by partially dry-etching back the tungsten contact after or during the M1 RIE process. The recessed contact is then subsequently metalized during the M1 liner/plating process. The tungsten contact height is reduced after it has been fully formed.

摘要: Methods for sealing an organic ILD layer and a metal layer after an etching step. The method includes etching through an ILD layer and leaving a remaining portion of an underlying metal layer cap, maintaining the device in an inert gas, and depositing at least a portion of a liner into the opening to seal the ILD layer and the metal layer. Subsequent processing may include formation of a via by etching through the portion of the liner and the remaining portion of the cap layer, and depositing a metal.
