Patent number: 11908728Abstract: Techniques herein include a process chamber for depositing thin films to backside surfaces of wafers to reduce wafer bowing and distortion. A substrate support provides an annular perimeter seal around the bottom and/or side of the wafer which allows the majority of the substrate backside to be exposed to a process environment. A supported wafer separates the chamber into lower and upper chambers that provide different process environments. The lower section of the processing chamber includes deposition hardware configured to apply and remove thin films. The upper section can remain a chemically inert environment, protecting the existing features on the top surface of the wafer. Multiple exhausts and differential pressures are used to prevent deposition gasses from accessing the working surface of a wafer.Type: GrantFiled: July 27, 2018Date of Patent: February 20, 2024Assignee: Tokyo Electron LimitedInventors: Ronald Nasman, Gerrit J. Leusink, Rodney L. Robison, Hoyoung Kang, Daniel Fulford

Patent number: 10426001Abstract: A processing system is disclosed, having a process chamber that houses a substrate for exposure of a surface of the substrate to a travelling electromagnetic (EM) wave. The processing system also includes an EM wave transmission antenna configured to launch the travelling EM wave into the process chamber for the travelling EM wave to propagate in a direction substantially parallel to the surface of the substrate. The processing system also includes a power coupling system configured to supply EM energy into the EM wave transmission antenna to generate the travelling EM wave at a prescribed output power and in a prescribed EM wave mode during treatment of the substrate. The processing system also includes an EM wave receiving antenna configured to absorb the travelling EM wave after propagation through the process chamber.Type: GrantFiled: March 3, 2014Date of Patent: September 24, 2019Assignee: Tokyo Electron LimitedInventors: Ronald Nasman, Mirko Vukovic, Gerrit J. Leusink, Rodney L. Robison, Robert D. Clark

Patent number: 10403501Abstract: Techniques herein include a bladder-based dispense system using an elongate bladder configured to selectively expand and contract to assist with dispense actions. This dispense system compensates for filter-lag, which often accompanies fluid filtering for microfabrication. This dispense system also provides a high-purity and high precision dispense unit. A process fluid filter is located downstream from a process fluid source as well as a system valve. Downstream from the process fluid filter there are no valves. Dispense actions can be initiated and stop while the system valve is open by using the elongate bladder. The elongate bladder can be expanded to stop or pause a dispense action, and then be contracted to assist with a dispense action.Type: GrantFiled: August 11, 2017Date of Patent: September 3, 2019Assignee: Tokyo Electron LimitedInventors: Anton J. deVilliers, Rodney L. Robison, Ronald Nasman, David Travis, James Grootegoed, Norman A. Jacobson, Jr., Lior Huli, Joshua S. Hooge

Patent number: 10354872Abstract: Techniques herein include a bladder-based dispense system using an elongate bladder configured to selectively expand and contract to assist with dispense actions. This dispense system compensates for filter-lag, which often accompanies fluid filtering for microfabrication. This dispense system also provides a high-purity and high precision dispense unit. A meniscus sensor monitors a position of a meniscus of process fluid at a nozzle. The elongate bladder unit is used to maintain a position of the meniscus at a particular location by selectively expanding or contracting the bladder, thereby moving or holding a meniscus position. Expansion of the elongate bladder is also used for a suck-back action after completing a dispense action.Type: GrantFiled: August 11, 2017Date of Patent: July 16, 2019Assignee: Tokyo Electron LimitedInventors: Anton J. deVilliers, Rodney L.

Patent number: 7901545Abstract: An iPVD system is programmed to deposit uniform material, such as barrier material, into high aspect ratio nano-size features on semiconductor substrates using a process which enhances the sidewall coverage compared to the field and bottom coverage(s) while minimizing or eliminating overhang within a vacuum chamber. The iPVD system is operated at low target power and high pressure >50 mT to sputter material from the target. RF energy is coupled into the chamber to form a high density plasma. A small RF bias (less than a few volts) can be applied to aid in enhancing the coverage, especially at the bottom.Type: GrantFiled: March 26, 2004Date of Patent: March 8, 2011Assignee: Tokyo Electron LimitedInventors: Frank M.
