== | =SEM Supra 1= | ||
The SEM Supra 1 a scanning electron microscope. It produces enlarged images of a variety of specimens, achieving magnifications of over 500.000x providing ultra high resolution imaging. This important and widely used analytical tool provides exceptional resolution and depth of field and requires minimal specimen preparation. | |||
The SEM is a VP (variable pressure) instrument - Indicating that it is capable of operating at variable pressure. By increasing the pressure in the chamber it is possible to image isolating samples. The higher density of gas molecules will eliminate the charges at the cost of slightly reduced resolution. Also, the Se2 and InLens detectors will no longer work. | |||
The SEM is the training SEM at DTU Danchip. It means that all new SEM users with no or little SEM experience must be trained on this tool and gain basic knowledge here before being qualified for training on other SEM's. | |||
The SEM Supra 1 was installed in the cleanroom in November 2010, but it has now been relocated in the basement outside the cleanroom, so that users can avoid to clean samples that have been outside the cleanroom before SEM inspection. | |||
The Balzer Sputter is located in the same room as the SEM Supra 1 and can be used to cover samples (for instance polymer samples from the Polymer Injection Molding tool) with a thin gold layer before SEM inspection to avoid charging problems. | |||
Only users with samples that are somehow related to the cleanroom can use this SEM. Other users will have to contact DTU CEN. | |||
