3D Optical nanometrology

In ERP 3D nanomanufacturing, several optical techniques have been investigated to go further than the classical optical resolution limit. Most of these technologies rely on fluorescence or switching on / off of certain molecules. In nanoelectronics industry working with fluorescence will not work, since these materials are not allowed in the semiconductor manufacturing industry. Therefore a couple of alternatives have to be found and investigated.

The following figure 1 gives a partial overview of the most relevant techniques, which was studies in 2015.

Of these techniques the following ones have been investigated in the ERP.
