Patent number: 9349573Abstract: A substrate located in an energetic-beam instrument has a region of interest to be extracted as a sample for further analysis. Cuts are made in the substrate to define a sample, and a stress-buffer layer is formed over the region of interest or adjacent to it. An isolating cut is made to separate the portion of the substrate containing the region of interest from the bulk substrate; however, the isolated area remains attached to the stress-buffer layer. An end-effector, such as the probe of a nano-manipulator, is attached to the stress-buffer layer, and the stress-buffer layer is cut to free the sample. The sample may then be attached to a holder by attachment of the stress-buffer layer thereto. Thus the sample is never at the same time connected directly and rigidly to two different objects that may move relatively to one another, creating undesirable stresses in the sample.Type: GrantFiled: July 11, 2015Date of Patent: May 24, 2016Assignee: Omniprobe, Inc.Inventors: Rocky Kruger, Gonzalo Amador, Cheryl Hartfield

Publication number: 20150318141Abstract: A gas injection system for an energetic-beam instrument having a vacuum chamber. The system has a cartridge containing a chemical serving as a source for an output gas to be delivered into the vacuum chamber. The cartridge has a reservoir containing the chemical, which rises to a fill line having a level defined by an amount of the chemical present in the reservoir at a given time. An outlet from the reservoir is coupled to an output passage through an outlet valve and configured so that when the system is tilted the outlet remains above the level of the fill line. Embodiments include isolation valves allowing the cartridge to be disconnected without destroying system vacuum.Type: ApplicationFiled: July 13, 2015Publication date: November 5, 2015Inventors: Rocky Kruger, Aaron Smith, Cheryl Hartfield

Patent number: 8512474Abstract: A precursor delivery system for an irradiation beam instrument includes an injection tube for injecting gasses into the instrument vacuum chamber and a main gas line having an inlet and an outlet. The outlet is connected to the injection tube, and the inlet is connected to a sequential pair of valves connected to a carrier gas source. A crucible for holding precursor material is selectively connected to the main gas line at a location between the pair of valves and the injection tube. The source of carrier gas may be selectively connected to the inlet by sequential operation of the pair of carrier gas valves, so that pulses of carrier gas assist the flow of precursor material to the injection tube. Rapid purging of the system between precursors is enabled by a valve selectively connecting the main line to an envelope in communication with the instrument vacuum.Type: GrantFiled: January 25, 2012Date of Patent: August 20, 2013Assignee: Omniprobe, Inc.Inventors: Rocky Kruger, Aaron Smith, Thomas M.

Patent number: 7961397Abstract: A single-channel optical processing system for an energetic-beam instrument has separate sources for processing radiation and illumination radiation. The processing radiation and the illumination radiation are combined in a single optical path and directed to a sample surface inside the energetic-beam instrument through a self-focusing rod lens. The self-focusing rod lens thus has a working distance from the sample surface that will not interfere with typical arrangements of ion beams and electron beams in such instruments. A combination of polarizers and beam splitters allows separation of the combined incident radiation and the combined radiation reflected from the sample surface and returned through the same optical channel, so that the reflected radiation may be directed to an optical detector, such as a camera or spectrometer. In other embodiments, additional illumination of the sample surface is provided at an angle to the central axis of the self-focusing rod lens.Type: GrantFiled: August 29, 2008Date of Patent: June 14, 2011Assignee: Omniprobe, IncInventors: Herschel M. Marchman, Thomas M. Moore, Rocky Kruger

Publication number: 20100068408Abstract: We disclose method for materials deposition on a surface inside an energetic-beam instrument, where the energetic beam instrument is provided with a laser beam, an electron beam, and a source of precursor gas. The electron beam is focused on the surface, and the laser beam is focused to a focal point that is at a distance above the surface of about 5 microns to one mm, preferably from 5 to 50 microns. The focal point of the laser beam will thus be within the stream of precursor gas injected at the sample surface, so that the laser beam will facilitate reactions in this gas cloud with less heating of the surface. A second laser may be used for cleaning the surface.Type: ApplicationFiled: September 16, 2008Publication date: March 18, 2010Applicant: Omniprobe, Inc.Inventors: Lyudmila Zaykova-Feldman, Rocky Kruger, Thomas M.
