The external quantum efficiency of Schottky photodetectors can be improved using nanophotonic structures, which enhance the absorption of the device. However, the electrical properties of Schottky photodetectors deviate under an altered metal-semiconductor interface topography. We characterize a common layer system for metal contacts consisting of a TiN interstitial layer between the p-Si wafer and the AlSiCu metallization. By varying the thickness of the TiN we discuss how homogeneity of the sputtered layers influence device properties with different interface topographies. Through electrical wafer-level characterization, the characteristics of the Schottky contact are evaluated and compared to the ideal physical modelling.}, language = {en} } @misc{AugelWenKnobbe, author = {Augel, Lion and Wen, Hanying and Knobbe, Jens}, title = {TiN-Si Schottky Diodes for SWIR Detection}, series = {Tagungsband MikroSystemTechnik Kongress 2023, Dresden, 23. - 25.
