Publication number: 20120085638Abstract: A multi-chamber processing system is described for depositing materials on multiple workpieces (wafers, display panels, or any other workpieces) at a time in a vacuum chamber. The system includes a sputtering chamber and a separate pre-clean chamber, where wafers can be transferred between the two chambers by a robotic arm without breaking a vacuum. The wafers are mounted one-by-one onto a rotating first pallet in the pre-cleaning chamber through a single entrance/exit port. After a batch cleaning, the robotic arm transfers the wafers one-by-one to a rotating second pallet in a sputtering chamber through a single entrance/exit, where the wafers are subjected to a batch sputtering process. After the sputtering process, the robotic arm transfers the wafers one-by-one to a load lock.Type: ApplicationFiled: December 16, 2011Publication date: April 12, 2012Applicant: TANGO SYSTEMS, INC.Inventors: Ravi Mullapudi, Dean Smith, Edward Strepka, Srikanth Dasaradhi

Patent number: 8092659Abstract: A multi-chamber processing system is described for depositing materials on multiple workpieces (wafers, display panels, or any other workpieces) at a time in a vacuum chamber. The system includes a sputtering chamber and a separate pre-clean chamber, where wafers can be transferred between the two chambers by a robotic arm without breaking a vacuum. The wafers are mounted one-by-one onto a rotating pallet in the pre-cleaning chamber and sputtering chamber. The pallet is firmly fixed to a rotatable table in the sputtering chamber. Copper tubing in the table couples RF energy to the wafers, and a liquid running through the copper tubing controls the temperature of the wafers. Multiple targets, of the same or different materials, may concurrently deposit material on the wafers as the pallet is rotating. Multiple magnets (one for each target) in the magnetron assembly in the sputtering chamber oscillate over their respective targets for uniform target erosion and uniform deposition on the wafers.Type: GrantFiled: January 21, 2009Date of Patent: January 10, 2012Assignee: Tango Systems, Inc.Inventors: Ravi Mullapudi, Dean Smith, Edward Strepka, Srikanth Dasaradhi

Patent number: 7744730Abstract: A processing system is described for depositing materials on multiple workpieces (wafers, display panels, or any other workpieces) at a time in a vacuum chamber. Multiple targets, of the same or different materials, may concurrently deposit material on the wafers as the pallet is rotating. Multiple magnets (one for each target) in the magnetron assembly in the sputtering chamber oscillate back and forth across an arc over their respective targets for uniform target erosion and uniform deposition on the wafers.Type: GrantFiled: April 14, 2005Date of Patent: June 29, 2010Assignee: Tango Systems, Inc.Inventors: Ravi Mullapudi, Edward Strepka
