The Hitachi SU8000 cold field emission Scanning Electron Microscope (FE-SEM) uses a focussed beam of high-energy electrons to generate a variety of signals at the surface of solid specimens. The signals that derive from the electron-sample interactions reveal information about the sample including external morphology (texture), chemical composition, crystalline structure and orientation of materials making up the sample. In most applications, data are collected over a selected area of the surface of the substrate and an image is generated that displays spatial variations in these properties. Areas ranging from a few mms to several 10s of nms in width can be imaged in a scanning mode using conventional SEM techniques (magnification ranging from 45X to 1,000,000X). The SEM is also capable of performing analyses of selected point locations on the sample, this approach is especially useful in qualitatively or semi-quantitatively determining chemical compositions (using EDS), crystalline structure, and crystal orientations (using BSD).

The Hitachi SU8000 In-line FE-SEM is designated as a General class tool. Below is a list of approved materials for the tool. Approved means the material is allowed in the tool under normal circumstances. If a material is not listed, please create a helpdesk ticket or email firstname.lastname@example.org for any material requests or questions.
There are no Standard Processes for the Hitachi SU8000 In-Line FE-SEM. However, having the right detector settings and probe current are extremely important in order to analyze your specimen. Please use the image below to choose which detector/combination of detectors to use for your specific application.
Secondary Electron detection (SED) is the most commonly used imaging mode. Please use the screenshot below to set the detectors to defaults, both in the Low Mag and High Mag mode, for secondary electron imaging.
Standard Operating Procedure
Widget text will go here.
- Read through this page and the Standard Operating Procedure above.
- Create a Helpdesk Ticket requesting training.
- If you already have an authorized instrument user in your research group, the tool engineer will ask you to get the initial training from the authorized user. Otherwise the tool engineer will schedule an initial training session.
- Practice with your mentor/another authorized user/authorized staff member until you are comfortable with tool operation.
- Schedule a checkout session with a tool engineer via the helpdesk ticket system. If this checkout is successful, the engineer will authorize you on the tool.
Users are not allowed to carry out maintenance on the In-Line SEM. For issues with the tool, please contact the tool engineer or create a helpdesk ticket. Users are prohibited from trying to troubleshoot without authorization from the tool engineers. The users are, however, allowed to exit and restart the SEM software in case error messages pop up or the software freezes. Double click in the PC SEM icon on the desktop to launch the software.
