Abstract

In this work, we present an integration concept for plasmonic Titanium Nitride (TiN) nanohole arrays (NHA) into a 200 mm BiCMOS silicon (Si) technology. For the fabrication of a TiN NHA, we investigated the TiN layer surface roughness in dependence on different process variations. Moreover, we developed a process module to release the TiN NHA to enable a direct contact with materials to be analyzed. By using an amorphous silicon (a-Si) stop layer, we are able to realize a controlled stop at the bottom level of the TiN NHA.
