Patent number: 7521089Abstract: Method and apparatus for controlling the migration of reaction by-product gases from a chemical vapor deposition (CVD) process chamber to a transfer vacuum chamber shared by other process chambers. Separate regulated flows of purge gas are provided to the CVD process chamber and the transfer vacuum chamber before establishing a pathway for substrate transfer. A pressure differential is created between the transfer vacuum chamber and the CVD process chamber that reduces or prevents the migration of CVD reaction by-product gases arising from the establishment of the substrate transfer pathway. While the pathway is established, a directional flow of purge gas is maintained from the transfer vacuum chamber into the CVD process chamber.Type: GrantFiled: June 13, 2002Date of Patent: April 21, 2009Assignee: Tokyo Electron LimitedInventors: Joseph T.

Patent number: 6482477Abstract: A method for chemical vapor deposition comprises providing a quantity of nitrogen at the interface between a transition metal-based material and an underlying dielectric-covered substrate. The nitrogen can be provided by heating the substrate in an atmosphere of a nitrogen-containing process gas or by exposing the surface of the dielectric-covered substrate to a plasma generated from a nitrogen-containing process gas. In certain embodiments, the nitrogen on the surface of the dielectric is bound with atoms of a transition metal to form a thin layer of a transition metal nitride. The method promotes the adhesion of the transition metal-based layer to the dielectric by nullifying the effect of halogen atoms that are also incorporated at the transition metal/dielectric interface.Type: GrantFiled: November 28, 2000Date of Patent: November 19, 2002Assignee: Tokyo Electron LimitedInventors: Richard C. Westhoff, Steven P. Caliendo, Joseph T. Hillman

Patent number: 6455414Abstract: A method for improving adhesion of copper films to transition metal based barrier layers. Tantalum or other transition metal based barrier layers are deposited by chemical vapor deposition techniques using transition metal halide precursor materials which generate halogen atom impurities in the barrier layer. The barrier layer is treated with a plasma generated from a nitrogen-containing gas, such as ammonia. Halogen impurity levels are thereby decreased at the surface of the barrier layer. On this surface is subsequently applied a copper film by physical vapor deposition. The copper film exhibits improved adherence to the barrier layer.Type: GrantFiled: November 28, 2000Date of Patent: September 24, 2002Assignee: Tokyo Electron LimitedInventors: Joseph T. Hillman, Cory S. Wajda, Steven P. Caliendo
