Abstract:
A TEM grid provides posts having steps, the steps increasing the number of samples that can be attached to the grid. In some embodiments, each post includes a one sided stair step configuration. A method of extracting multiple samples includes extracting samples and attaching the samples to the different stair steps on the posts.
Abstract:
A method of ion implantation comprising: providing a plasma within a plasma region of a chamber; positively biasing a first grid plate, wherein the first grid plate comprises a plurality of apertures; negatively biasing a second grid plate, wherein the second grid plate comprises a plurality of apertures; flowing ions from the plasma in the plasma region through the apertures in the positively-biased first grid plate; flowing at least a portion of the ions that flowed through the apertures in the positively-biased first grid plate through the apertures in the negatively-biased second grid plate; and implanting a substrate with at least a portion of the ions that flowed through the apertures in the negatively-biased second grid plate.
Abstract:
The invention relates to a sample carrier (10) for a transmission electron microscope. When using state of the art sample carriers, such as half-moon grids in combination with detectors detecting, for example, X-ray emitted at a large emittance angle, shadowing is a problem. Similar problems occur when performing tomography, in which the sample is rotated over a large angle. The invention provides a solution to shadowing by forming the parts (16) of the grid bordering the interface between sample and grid as tapering parts.
Abstract:
A device, method and system for preparing and storing samples for microscopic analysis is disclosed. The device provides a reservoir that can be attached to a displacement pipette thereby filling the reservoir with reagents desired for preparing the samples for microscopic analysis. In some embodiments, the specimen may be contained on a transmission electron microscope (TEM) grid. In other embodiments, the sample may be a light microscope (LM) specimen or a scanning electron microscope (SEM) specimen. In yet another embodiment, the invention provides a method of preparing samples for microscopic examination including a device for preparing TEM grids with, a device for preparing TEM, SEM or LM specimens with and a device for storing both grids and specimens in. In yet another embodiment, the invention provides a system for tracking the preparation, analysis and histological evaluation of multiple samples while also providing for their long term storage.
Abstract:
A specimen holder for an electron microscope, comprising a bar-shaped body provided adjacent one end with means for receiving a specimen, with means being present for screening the specimen from the environment at least temporarily in airtight and moisture-proof manner in a first position, which screening means comprise at least one elastic seal surrounding the bar-shaped body at least in the first position, and supporting means for arranging the specimen holder in a service position. In a second position, wherein the screening means have been removed from the first position, the bar-shaped body with the specimen-receiving means is supported by the supporting means without intermediacy of the elastic seal. The invention further relates to a device for mounting a specimen in an electron microscope.
