Integrated Circuit Plating Using Highly-Complexed Copper Plating Baths

View page
US Patent:
6709564, Mar 23, 2004
Filed:
Sep 30, 1999
Appl. No.:
09/410250
Inventors:
D. Morgan Tench - Camarillo CA
John T. White - Lancaster CA
Dieter Dornisch - Carlsbad CA
Maureen Brongo - Laguna Hills CA
Assignee:
Rockwell Scientific Licensing, LLC - Thousand Oaks CA
International Classification:
C25D 338
US Classification:
205291, 205293, 205296, 205298
Abstract:
The acid copper sulfate solutions used for electroplating copper circuitry in trenches and vias in IC dielectric material in the Damascene process are replaced with a type of plating system based on the use of highly complexing anions (e. g. , pyrophosphate, cyanide, sulfamate, etc. ) to provide an inherently high overvoltage that effectively suppresses runaway copper deposition. Such systems, requiring only one easily-controlled organic additive species to provide outstanding leveling, are more efficacous for bottom-up filling of Damascene trenches and vias than acid copper sulfate baths, which require a minimum of two organic additive species. The highly complexed baths produce fine-grained copper deposits that are typically much harder than large-grained acid sulfate copper deposits, and which exhibit stable mechanical properties that do not change with time, thereby minimizing âdishingâ and giving more consistent CMP results. The mechanical properties and texture of the fine-grained deposits are also much less substrate dependent, which minimizes the effects of variations and flaws in the barrier and seed layers. The resistivity of pyrophosphate and annealed acid sulfate copper deposits are approximately equivalent.

US Classification:
438669, 438671, 438712, 438720, 438942, 438945
Abstract:
A method of patterning a metal layer in a semiconductor die comprises forming a mask on the metal layer to define an open region and a dense region. The method further comprises etching the metal layer at a first etch rate to form a number of metal segments in the open region and etching the metal layer at a second etch rate to form a number of metal segments in the dense region, where the first etch rate is approximately equal to the second etch rate. The method further comprises performing a number of strip/passivate cycles to remove a polymer formed on sidewalls of the metal segments in the dense region. The sidewalls of the metal segments in the dense region undergo substantially no undercutting and residue is removed from the sidewalls of the metal segments in the dense region.

Abstract:
A method for the removal and purification of substantially all of the fluoride ions contained in a solution containing greater than 10 parts per million (ppm) fluoride ion, a mixture of other anions, silicon in the form of a fluorosilicic acid, silicic acid, silicates, or silicon tetrafluoride, and optionally also containing complex metal fluorides, to produce an ultrapure hydrofluoric acid, comprising the steps of (a) adjusting the pH of the solution to an alkaline pH to hydrolyze the fluorosilicic acid and any complex metal fluorides; (b) removing the fluoride ions and other anions from the solution by passing the solution through an ion exchange resin, where the ion exchange resin is adapted to adsorb substantially all of the fluoride passed over the ion exchange resin; (c) displacing the fluoride ions and other anions bound to the ion exchange resin, thereby forming a mixture of anions in an effluent emanating from resin; (d) optionally concentrating the effluent at a high pH and then lowering the pH; and (e) distilling the mixture of anions in the effluent from a sulfuric acid solution to generate ultrapure hydrofluoric acid. An apparatus useful for practicing the method is also disclosed.
