Working student: Physics-Based Circuit-Compatible SPICE model for Ferroelectric Tunnel Junction

Developing innovative technology solutions and bringing them to application - that is our goal at the Fraunhofer Institute for Photonic Microsystems IPMS . With our expertise in the development of photonic microsystems, related technologies including nanoelectronics and wireless communication solutions, we create - in flexible and interdisciplinary teams - technologies for innovative products in a wide range of markets such as automotive, industrial and aerospace.

The development of new components and integration concepts for semiconductor devices with a wide range of applications is an important field of research at the Center Nanoelectronic Technologies (CNT) of the Fraunhofer IPMS. One research focus is on the development of non-volatile memory technologies based on ferroelectric hafnium oxide. These are used beyond traditional storage applications, including AI applications. To design a full memory array and use it for AI applications, an effective ferroelectric device model is needed. Students will work with our teams to develop a SPICE model for the Ferroelectric Tunnel Junction (FTJ). Further, it will be programmed with Verilog-A language and integrated with Spectra EDA.
