Ultra-Small Device Engineering Laboratory

Subject of Research

Transistor Development for Next Generations
Through collaboration with industries we are working for ultra-thin-film transistors as an ideal transistor structure. We are also working for new material devices to realize better ecology of transistors.
Measuring and Modeling of Carrier Dynamics in Transistors
Undesired phenomena are being observed in the course of the transistor performance evolution. The dynamics of single carrier influence strongly on the performance of small size transistors. We are working for setting up measurement equipments and elucidating the origin of the carrier dynamics by appropriate theoretical modeling.
Development of world standard model HiSIM
One of our achievements has been selected as a standard circuit-simulation model for the world’s semiconductor industry and is thus used world widely. The model is names HiSIM and is a compact model for describing transistor performances with very essential equations. The developed models are delivered into the public domain through our homepage.
Development of Organic Transistors Synthesizing with Silicon Transistors
In a synergy project within our university, which includes research groups specialized in the field of medicine and chemistry, we are working towards the development of an artificial lung. Our contribution is to realize the necessary integrated circuits with flexible organic transistors on plastic material.
Facilities
Facilities required to measure unexpected phenomena are provided together with those resources necessary to setup new types of measurement systems. To simulate carrier dynamics and to investigate the origin of the transistor performances, more than 60 PC are also provided.

Message to Prospective Students

Most of organic and biological materials are semiconductors. Transistors realized with those materials must have the same characteristics as conventional silicon transistors. We can contribute to a further step in transistor evolution by understanding the principles of the transistor performance with these unconventional materials for different practical aspects.
