Systems and methods for operating a broad ion beam (BIB) polisher in a sample preparation workflow having improved uptime, are disclosed. An example method for operating a broad ion beam (BIB) polisher having improved uptime according to the present invention comprises causing a first BIB source to emit a first broad ion beam towards a sample positioned within an interior volume of the BIB polisher while the first BIB source is in emitting the first broad ion beam towards the sample, removing a second BIB source from the BIB polisher that is configured to emit a second broad ion beam towards the sample when in use.

Broad ion beam (BIB) systems for more efficient processing of multiple samples

The present invention relates to a method for preparing and/or processing a sample. The sample comprises at least one fluid, and the method comprises directing a charged particle beam onto the at least one fluid and causing the at least one fluid to flow in response to the charged particle beam being directed on to it. The present invention also relates to a system and a computer program product used to carry out the method.

Systems and methods for efficiently processing multiple samples with a BIB system, are disclosed. An example method for efficiently processing multiple samples with a BIB system according to the present invention comprises removing an individual sample holder containing a sample from a storage location within the BIB system, wherein the BIB system includes multiple sample holders positioned in one or more storage locations, loading the individual sample holder onto a sample stage configured to hold the sample holder during polishing of the corresponding sample held by the individual sample holder, and causing a BIB source to emit a broad ion beam towards the sample, wherein the broad ion beam removes at least a portion of the sample upon which it is incident. Once a desired portion of the sample is removed, the sample holder is removed from the sample stage and loaded back into the storage location.

System and methods for automated processing of multiple samples in a BIB system

Systems and methods for pre-aligning samples for more efficient processing of multiple samples with a BIB system according to the present invention comprises affixing a sample to an adjustable portion of a sample holder, nesting the sample holder with a first mask having a first mask edge, wherein the first mask is positioned outside of a BIB system, and aligning the sample such that it has a desired geometric relationship to the first mask edge. The first mask may be geometrically similar with a second mask within the BIB system that has a second mask edge such that the geometric relationship between the first mask edge and the sample when the sample holder is nested with the first mask is the same as the geometric relationship between the second mask edge and the sample when the sample holder is nested with the second mask.

A system for positioning a sample in a charged particle apparatus (CPA) or an X-ray photoelectron spectroscopy (XPS) system includes a sample carrier coupled to a stage inside the vacuum chamber of the CPA or XPS system. The system allows transferring of the sample carrier among multiple CPAs, XPS systems and glove boxes in inert gas or in vacuum. The sample carrier is releasably coupled with the stage in the vacuum chamber of the CPA or the XPS. Multiple electrodes in a sample area of the sample carrier are electrically connectable with the stage by multiple spring contacts between the sample carrier and the stage.

Method and system for positioning and transferring a sample

Disclosed is a method of using a charged particle microscope for inspecting a sample mounted on a sample holder. The microscope is equipped with a solid state detector for detecting secondary particles emanating from the sample in response to irradiation of the sample with the primary beam, with the solid state detector in direct optical view of the sample. In some embodiments, the sample is mounted on a heater with a fast thermal response time. The method comprises contactless measurement of the temperature of the sample and/or sample holder using the solid state detector.

An environmental cell for a charged particle beam system allows relative motion between the cell mounted on an X-Y stage and the optical axis of the focusing column, thereby eliminating the need for a sub-stage within the cell. A flexible cell configuration, such as a retractable lid, permits a variety of processes, including beam-induced and thermally-induced processes. Photoelectron yield spectroscopy performed in a charged particle beam system and using gas cascade amplification of the photoelectrons allows analysis of material in the cell and monitoring of processing in the cell. Luminescence analysis can be also performed using a retractable mirror.
