摘要： A compact electron microscope uses a removable sample holder having walls that form a part of the vacuum region in which the sample resides. By using the removable sample holder to contain the vacuum, the volume of air requiring evacuation before imaging is greatly reduced and the microscope can be evacuated rapidly. In a preferred embodiment, a sliding vacuum seal allows the sample holder to be positioned under the electron column, and the sample holder is first passed under a vacuum buffer to remove air in the sample holder.

摘要： In one embodiment of the present invention, a magnetic lens is provided that can generate a substantially constant amount of average heat power over a pre-selected range of resultant magnetic field strengths. The lens is configured to do this with multiple, asymmetric (different turns) coil sections that can produce a desired range of field strengths, and at the same time, maintain a sufficiently constant temperature signature when the average total power is maintained constant thereby eliminating unreasonable delays in lens operation when the resultant field strength is changed. The asymmetric lens structure allows for the smaller coil to be made with less relative inductance thereby making it more responsive and amenable for an AC drive signal and thus dynamic focusing applications if desired. Thus, a magnetic lens is now provided that can produce a range of magnetic beam-focusing field strengths, implement dynamic focusing, and not impose unreasonable delay for thermal stabilization between changes in magnetic field strength.

摘要： A user interface for operation of a scanning electron microscope device that combines lower magnification reference images and higher magnification images on the same screen to make it easier for a user who is not used to the high magnification of electron microscopes to readily determine where on the sample an image is being obtained and to understand the relationship between that image and the rest of the sample. Additionally, other screens, such as, for example, an archive screen and a settings screen allow the user to compare saved images and adjust the settings of the system, respectively.
