Patent number: 8399831Abstract: Dual beam instruments, comprising a Scanning Electron Microscope (SEM) column for imaging and a Focused Ion Beam (FIB) column for milling, are routinely used to extract samples (lamellae) from semiconductor wafers. By observing the progress of the milling with the SEM column, end pointing of the milling process can be performed. The invention offers an alternative solution to this problem, in which an instrument with only a FIB column is used. For milling a lamella to its final thickness of, for example, 30 nm, the focused ion beam 100, is scanned repeatedly along the lamella. It is found that while milling the lamella a signal can be derived from the lamella that is sufficient for end pointing. No additional electron beam for inspection is needed.Type: GrantFiled: March 26, 2010Date of Patent: March 19, 2013Assignee: FEI CompanyInventors: Jacob Simon Faber, Remco Theodorus Johannes Petrus Geurts

Patent number: 8399851Abstract: Systems and methods of an ion implant apparatus include an ion source for producing an ion beam along an incident beam axis. The ion implant apparatus includes a beam deflecting assembly coupled to a rotation mechanism that rotates the beam deflecting assembly about the incident beam axis and deflects the ion beam. At least one wafer holder holds target wafers and the rotation mechanism operates to direct the ion beam at one of the at least one wafer holders which also rotates to maintain a constant implant angle.Type: GrantFiled: February 15, 2011Date of Patent: March 19, 2013Inventor: John Ruffell

Patent number: 8389962Abstract: A system and method for noise compensation of a charged particle beam location includes one or more sensors that are spaced apart from each other for sensing magnetic noises within at least one predefined frequency band thereby to provide magnetic noise measurements with synchronous detection of the location of a charged particle beam. Based on the magnetic noise measurements and on relationships between values of the magnetic noises and particle beam location errors, magnetic noise compensations signals are generated. An object is then scanned by a particle beam in response to a desired particle beam scan pattern and the magnetic noise compensation signals.Type: GrantFiled: May 31, 2011Date of Patent: March 5, 2013Assignee: Applied Materials Israel, Ltd.Inventors: Konstantine Chirko, Alon Litman, Yoav Nachum

Patent number: 8384048Abstract: The invention provides a method for patterning a resist coated substrate carried on a stage, where the patterning utilizes a charged particle beam. The method comprises the steps of: moving the stage at a nominally constant velocity in a first direction; while the stage is moving, deflecting the charged particle beam in the first direction to compensate for the movement of the stage, the deflecting including: (a) compensating for an average velocity of the stage; and (b) separately compensating for the difference between an instantaneous position of the stage and a calculated position based on the average velocity. The separately compensating step uses a bandwidth of less than 10 MHz. The invention also provides a deflector control circuit for implementing the separate compensation functions.Type: GrantFiled: June 25, 2008Date of Patent: February 26, 2013Assignee: Multibeam CorporationInventor: John C.

Patent number: RE44035Abstract: An instrument system is controlled to acquire an optical image of an object, with the optical image defining a first coordinate system. The object is positioned in a second coordinate system and a point in the optical image is selected. The object is repositioned so that a point on the object corresponding to the selected point in the optical image is positioned at a predetermined point in the second coordinate system. Alternatively, movement of the object causes an indicia on the optical image to move to a point thereon corresponding to the point on the object that is positioned at the predetermined point in the second coordinate system.Type: GrantFiled: January 28, 2009Date of Patent: March 5, 2013Assignee: FEI CompanyInventors: Frederick H.
