THz-LoC

Integrated Lab-on-Chip Terahertz-Spectroscopy Platform in BiCMOS Technology

Zielstellung

Goal of this project is the first-time demonstration of an ultra-broadband fully integrated microfluidic platform featuring terahertz (THz) spectroscopy sensors for future innovative Lab-on-Chip applications. The targeted platform will be realized in a single low-cost mass-manufacturable state-of-the-art SiGe BiCMOS technology. The proposed highly integrated demonstration platform will be applicable for studies of the real interaction between biological cells and electromagnetic fields on a single cell interaction level.

Beitrag des IHP

The contribution of the IHP departments Circuit Design and Technology is the development and combination of integrated complex THz vector network analyzer sensor readout circuits in the 240-500 GHz frequency range realized in the front-end of line (FEOL) technology with THz sensing element implementations and novel microfluidic channel integration using additionally integrated trapping electrodes in the back-end of line (BEOL) process.
