Patent number: 8916232Abstract: The embodiments fill the need of improving electromigration and reducing stress-induced voids of copper interconnect by enabling deposition of a thin and conformal barrier layer, and a copper layer in the copper interconnect. The adhesion between the barrier layer and the copper layer can be improved by making the barrier layer metal-rich prior copper deposition and by limiting the amount of oxygen the barrier layer is exposed prior to copper deposition. Alternatively, a functionalization layer can be deposited over the barrier layer to enable the copper layer being deposit in the copper interconnect with good adhesion between the barrier layer and the copper layer. An exemplary method of preparing a substrate surface of a substrate to deposit a functionalization layer over a metallic barrier layer of a copper interconnect to assist deposition of a copper layer in the copper interconnect in an integrated system in order to improve electromigration performance of the copper interconnect is provided.Type: GrantFiled: December 13, 2006Date of Patent: December 23, 2014Assignee: Lam Research CorporationInventors: Hyungsuk Alexander Yoon, John Boyd, Yezdi Dordi, Fritz C.

Publication number: 20120058254Abstract: Disclosed is an electroless plating solution exhibiting a good plating metal filling performance even for larger trenches or vias of several to one hundred and tens of ?m, in a manner free from voids or seams, and allowing maintenance of stabilized performance for prolonged time. The electroless plating solution contains at least a water-soluble metal salt, a reducing agent for reducing metal ions derived from the water-soluble metal salt, and a chelating agent. In addition, the electroless plating solution contains a sulfur-based organic compound as a leveler having at least one aliphatic cyclic group or aromatic cyclic group to which may be linked at least one optional substituent. The aliphatic cyclic group or the aromatic cyclic group contains optional numbers of carbon atoms, oxygen atoms, phosphorus atoms, sulfur atoms and nitrogen atoms.Type: ApplicationFiled: November 14, 2011Publication date: March 8, 2012Applicant: C.

Publication number: 20120048600Abstract: A first artwork layer having a first adaptable-mask section allows a graded amount of light to pass into an underlying first photoresist layer. Subsequent to developing the first photoresist layer, the graded amount of light creates a rounded geometric void used as a mold or sidewall for the creation of at least a lower portion of a rounded trace. A dielectric layer is laminated upon the lower portion and a second artwork layer having an second adaptable-mask section allows a graded amount of light to pass into a second photoresist layer. Subsequent to developing the second photoresist layer, the graded amount of light creates a rounded geometric void used as a mold or sidewall for the creation of at least an upper portion of a rounded trace. The photoresist and dielectric layers are removed resulting in a circuit apparatus having a rounded differential pair trace.Type: ApplicationFiled: August 27, 2010Publication date: March 1, 2012Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Matthew S. Doyle, Joseph Kuczynski, Kevin A. Splittstoesser, Timothy J. Tofil
