Methods for aligning a particle beam and performing a non-contact electrical measurement on a cell using a registration cell
Systems, devices, and methods for performing a non-contact electrical measurement (NCEM) on a NCEM-enabled cell included in a NCEM-enabled cell vehicle may be configured to perform NCEMs while the NCEM-enabled cell vehicle is moving. The movement may be due to vibrations in the system and/or movement of a movable stage on which the NCEM-enabled cell vehicle is positioned. Position information for an electron beam column producing the electron beam performing the NCEMs and/or for the moving stage may be used to align the electron beam with targets on the NCEM-enabled cell vehicle while it is moving.
Adaptive geometry for optimal focused ion beam etching
A method of evaluating a region of a sample that includes alternating layers of different material. The method includes milling, with a focused ion beam, a portion of the sample that includes the alternating layers of different material; reducing the milling area; and repeating the milling and reducing steps multiple times during the delayering process until the process is complete.
COMBINING FOCUSED ION BEAM MILLING AND SCANNING ELECTRON MICROSCOPE IMAGING
The dual focused ion beam and scanning electron beam system includes an electron source that generates an electron beam and an ion source that generates an ion beam. The electron beam column directs an electron beam at a normal angle relative to a top surface of the stage. An ion beam column directs the ion beam at the stage. The ion beam is at an angle relative to the electron beam. A detector receives the electron beam reflected from the wafer on the stage.
Dual beam microscope system for imaging during sample processing
Methods for using a dual beam microscope system to simultaneously process a sample and image the processed portions of the sample, according to the present disclosure include the initial steps of emitting a plurality of electrons toward the sample, splitting the plurality of electrons into two electron beams, and then modifying the focal properties of at least one of the electron beams such that the two electron beams have different focal planes. Once the two beams have different focal planes, the first electron beam is focused such that it acts as a STEM beam. The STEM beam is then used to process a region of the sample to induce a physical change (e.g., perform milling, deposition, charge adjustment, phase change, etc.). The second electron beam is focused to act as a TEM beam to perform imaging of the region of the sample being processed.
Imaging Method and Imaging System
This invention pertains to an imaging method, the purpose of which is to reveal, over a wide range, information about a plurality of layers contained in a multilayer structure, or form an image of the revealed applicable layers. The method proposed includes: a step in which, while rotating the sample with the axis of the normal line of the sample surface as the axis of rotation, the sample is irradiated with an ion beam from a direction inclined with respect to the normal line direction, via a mask having an opening which selectively allows the passage of an ion beam and which is disposed at a position distant from the sample, thereby forming a hole with a band-shaped sloped surface that is inclined with respect to the sample surface; and a step in which a first image viewed from a direction intersecting with the sloped surface of the applicable layer is formed, on the basis of a signal obtained by irradiating, with a charged particle beam, the applicable layer contained in the band-shaped sloped surface.
UNIFORM MILLING OF ADJACENT MATERIALS USING PARALLEL SCANNING FIB
A method of evaluating a region of a sample that includes two or more sub-regions adjacent to each other that have different milling rates.
