| 20090014878 | STRUCTURE AND METHOD OF FORMING ELECTRODEPOSITED CONTACTS - A contact metallurgy structure comprising a patterned dielectric layer having cavities on a substrate; a silicide or germanide layer such as of cobalt and/or nickel located at the bottom of cavities; a contact layer comprising Ti or Ti/TiN located on top of the dielectric layer and inside the cavities and making contact to the silicide or germanide layer on the bottom; a diffusion barrier layer located on top of the contact layer and inside the cavities; optionally a seed layer for plating located on top of the barrier layer; a metal fill layer in vias is provided along with a method of fabrication. The metal fill layer is electrodeposited with at least one member selected from the group consisting of copper, rhodium, ruthenium, iridium, molybdenum, gold, silver, nickel, cobalt, silver, gold, cadmium and zinc and alloys thereof. When the metal fill layer is rhodium, ruthenium, or iridium, an effective diffusion barrier layer is not required between the fill metal and the dielectric. When the barrier layer is platable, such as ruthenium, rhodium, platinum, or iridium, the seed layer is not required. | 01-15-2009 |
| 20110084393 | METHOD OF FORMING ELECTRODEPOSITED CONTACTS - A contact metallurgy structure comprising a patterned dielectric layer having vias on a substrate; a silicide layer of cobalt and/or nickel located at the bottom of vias; a contact layer comprising Ti located in vias on top of the silicide layer; a diffusion layer located in vias and on top of the contact layer; a metal fill layer in vias is provided along with a method of fabrication. The metal fill layer comprises at least one member selected from the group consisting of copper, ruthenium, rhodium platinum, palladium, iridium, rhenium, tungsten, gold, silver and osmium and alloys thereof. When the metal fill layer comprises rhodium, the diffusion layer is not required. Optionally a seed layer for the metal fill layer can be employed. | 04-14-2011 |

| 20090152590 | METHOD AND STRUCTURE FOR SEMICONDUCTOR DEVICES WITH SILICON-GERMANIUM DEPOSITS - A method of forming a semiconductor device including forming a second deposit of silicon-germanium on a first deposit of silicon-germanium, the first deposit formed in a conduction terminal region of a substrate of the semiconductor device and having a first percentage of germanium, and the second deposit having a second percentage of germanium that is less than the first percentage and supports forming a silicide deposit on the second deposit. A structure is also provided. | 06-18-2009 |
| 20090309228 | METHOD FOR FORMING SELF-ALIGNED METAL SILICIDE CONTACTS - The present invention relates to a method for forming self-aligned metal silicide contacts over at least two silicon-containing semiconductor regions that are spaced apart from each other by an exposed dielectric region. Preferably, each of the self-aligned metal silicide contacts so formed comprises at least nickel silicide and platinum silicide with a substantially smooth surface, and the exposed dielectric region is essentially free of metal and metal silicide. More preferably, the method comprises the steps of nickel or nickel alloy deposition, low-temperature annealing, nickel etching, high-temperature annealing, and aqua regia etching. | 12-17-2009 |

| 20080274611 | METHOD AND PROCESS FOR FORMING A SELF-ALIGNED SILICIDE CONTACT - The present invention provides a method for forming a self-aligned Ni alloy silicide contact. The method of the present invention begins by first depositing a conductive Ni alloy with Pt and optionally at least one of the following metals Pd, Rh, Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, W or Re over an entire semiconductor structure which includes at least one gate stack region. An oxygen diffusion barrier comprising, for example, Ti, TiN or W is deposited over the structure to prevent oxidation of the metals. An annealing step is then employed to cause formation of a NiSi, PtSi contact in regions in which the metals are in contact with silicon. The metal that is in direct contact with insulating material such as SiO | 11-06-2008 |
