Simulation of Advanced Semiconductor Devices

Microelectronics is one of the most rapidly changing scientific fields today. Its influence on society is far-reaching, and a world without electronics is hardly imaginable. Simulation of the electrical characteristics of semiconductor devices enables manufacturers to estimate the behavior of their devices prior to the finished production cycle. Highly expensive test runs can be eliminated efficiently by deepening the understanding of the physical behavior. Using this knowledge enables also to optimize the devices in an early phase. In order to master these simulation tasks, sophisticated software tools are required, commonly referred to as TCAD tools. The capabilities of commercially available TCAD tools often lag behind for many leading edge applications. This project focuses on several highly important research topics, which are categorized into the following modules: Novel Materials and Devices: Development of models for the electrical and thermal properties of Group IV and Group III-V novel semiconductor materials, and non-ideal dielectrics. Devices based on these materials will be thoroughly investigated. Advanced Transport Models: This module is focused on the question of which carrier transport model is required for achieving the necessary accuracy for a given application. This is of particular relevance for the proper treatment of novel materials and devices as well.
