Patent number: 7060619Abstract: Interconnect layers on a semiconductor body containing logic circuits (microprocessors, Asics or others) or random access memory cells (DRAMS) are formed in a manner to significantly reduce the number of shorts between adjacent conductor/vias with narrow separations in technologies having feature sizes of 0.18 microns or smaller. This is accomplished by etching to form recessed copper top surfaces on each layer after a chemical-mechanical polishing process has been completed. The thickness of an applied barrier layer, on the recessed copper surfaces, is controlled to become essentially co-planar with the surrounding insulator surfaces. A thicker barrier layer eliminates the need for a capping layer. The elimination of a capping layer results in a reduction in the overall capacitive coupling, stress, and cost.Type: GrantFiled: March 4, 2003Date of Patent: June 13, 2006Assignee: Infineon Technologies AGInventors: Andy Cowley, Erdem Kaltalioglu, Mark Hoinkis, Michael Stetter

Patent number: 6432760Abstract: An improved fuse structure in an integrated circuit (IC) structure is made by forming a gate stack comprised of layers of polysilicon and a silicide. Subsequent to the formation of the silicide layer, an etch stop silicon nitride layer is deposited over the silicide layer. The silicon nitride layer is patterned to expose the silicide layer. A soft passivation layer is deposited over the exposed silicide layer. The soft passivation layer has a low thermal conductivity which confines energy in the silicide layer, minimizing the current needed to program the fuse. The inherent ductility of the soft passivation layer prevents the generation of cracks in the surrounding layers.Type: GrantFiled: December 28, 2000Date of Patent: August 13, 2002Assignees: Infineon Technologies AG, International Business Machines CorporationInventors: Chandrasekharan Kothandaraman, Michael Stetter, Sundar K.
