Publication number: 20210110995Abstract: An ion source with a target holder for holding a solid dopant material is disclosed. The ion source comprises a thermocouple disposed proximate the target holder to monitor the temperature of the solid dopant material. In certain embodiments, a controller uses this temperature information to vary one or more parameters of the ion source, such as arc voltage, cathode bias voltage, extracted beam current, or the position of the target holder within the arc chamber. Various embodiments showing the connections between the controller and the thermocouple are shown. Further, embodiments showing various placement of the thermocouple on the target holder are also presented.Type: ApplicationFiled: January 6, 2020Publication date: April 15, 2021Inventors: Shreyansh P.

Patent number: 10957509Abstract: An ion source with an insertable target holder for holding a solid dopant material is disclosed. The insertable target holder includes a hollow interior into which the solid dopant material is disposed. The target holder has a porous surface at a first end, through which vapors from the solid dopant material may enter the arc chamber. The porous surface inhibits the passage of liquid or molten dopant material into the arc chamber. The target holder is also constructed such that it may be refilled with dopant material when the dopant material within the hollow interior has been consumed. The porous surface may be a portion of a perforated crucible, a portion of a perforated retention cap, or a porous insert.Type: GrantFiled: November 7, 2019Date of Patent: March 23, 2021Assignee: Applied Materials, Inc.Inventors: Graham Wright, Daniel Alvarado, Shreyansh P.

Patent number: 10896799Abstract: An IHC ion source with multiple configurations is disclosed. For example, an IHC ion source comprises a chamber, having at least one electrically conductive wall, and a cathode and a repeller disposed on opposite ends of the chamber. Electrodes are disposed on one or more walls of the ion source. Bias voltages are applied to at least one of the cathode, repeller and the electrodes, relative to the electrically conductive wall of the chamber. Further, the IHC ion source comprises a configuration circuit, which receives the various voltages as input voltages, and provides selected output voltages to the cathode, repeller and electrodes, based on user input. In this way, the IHC ion source can be readily reconfigured for different applications without rewiring the power supplies, as is currently done. This configuration circuit may be utilized with other types of ion sources as well.Type: GrantFiled: August 29, 2019Date of Patent: January 19, 2021Assignee: Applied Materials, Inc.Inventors: Klaus Becker, Carlos M. Goulart, Daniel Alvarado, Daniel R. Tieger, Alexander S. Perel

Publication number: 20200090916Abstract: An ion source with an insertable target holder for holding a solid dopant material is disclosed. The insertable target holder includes a pocket or cavity into which the solid dopant material is disposed. When the solid dopant material melts, it remains contained within the pocket, thus not damaging or degrading the arc chamber. Additionally, the target holder can be moved from one or more positions where the pocket is at least partially in the arc chamber to one or more positions where the pocket is entirely outside the arc chamber. In certain embodiments, a sleeve may be used to cover at least a portion of the open top of the pocket.Type: ApplicationFiled: February 6, 2019Publication date: March 19, 2020Inventors: Shreyansh Patel, Graham Wright, Daniel Alvarado, Klaus Becker, Daniel R.
