== Scanning electron microscopy at | == Scanning electron microscopy in the cleanroom at DTU Nanolab== | ||
At | The number of electron microscopes at DTU Nanolab is large. | ||
At there are five SEMs (Scanning Electron Microscopes) that all cover a wide range of needs both in the cleanroom and outside: From fast in-process verification of different process parameters such as etch rates, step coverages or lift-off quality to ultra high resolution images on any type of sample intended for publication. | |||
* The SEM Supra 1 is located in the basement outside the cleanroom. It is serving two purposes: Serving the users that have samples from outside the cleanroom and serving as training tool; all new SEM users with no/little SEM experience must be trained on this tool and gain basic knowledge (typically 10 hours of usage) here before being qualified for training on the SEMs in the cleanroom. | * The SEM Supra 1 is located in the basement outside the cleanroom.
