Abstract:

Acquiring the skills to perform necessary production steps in microstructure technology is cumbersome due to the limited accessibility of a cleanroom. Offering a substantial number of students the possibility to actually work there is usually not possible and hands-on training possibilities on a beginner level are therefore limited. Our VR App provides realistic training in operating the machinery and understanding the processes behind the necessary tasks.

The VR app serves two purposes. First of all, learners train how to operate the machines and what steps are necessary in handling the sample. We create an immersive environment with realistic 3D models. This includes learning to handle prepare different samples and operating the vacuum chambers or evaporators.

In the second stage, students train the acquisition of images with a scanning electron microscope. We have implemented a virtual user interface together with a mathematical model of the image formation process. This allows for completely computer rendered images and thus the possibility to evaluate the performance of the students by learning analytics. They are steered through the adjustment process in order to train the relevant skills necessary to work in a cleanroom.
