Novel-Concept Silicon Integrated Circuits Derived from the 3-Dimensional Device, Circuit and Architecture

Features and Uniqueness
  • In recent year, facing the age of nanoscale engineering, the new technologies of device, circuit and architecture supported by novel physical guidance principles are highly expected, just as the similar situation as the predawn of semiconductor technology when Bardeen and Shockley discovered the secret of transistors. Therefore, in our research approach, the architectures, circuits, devices and CAD design tools for nanoscale LSI are systematically investigated in the following three main research subjects.
  • 1. Study on nanoscale device and circuit
  • Aiming at the nanoscale silicon semiconductor integrated circuit, we are mainly working on the following directions for new devices and circuits:
  • ①Analysis for novel physical phenomenon based on nanostructural effects
  • ②Device and circuit technology with new operating principle
  • ③Restraint technology for increasing variability of device characteristics
  • ④Architecture and circuit technology for robust information processing
  • 2. Study on the 3-dimention-structual device and circuit
  • The elementary element of recent LSI with planar-structural devices is coming close to the physical limitation of scaling. In order to break the limit and sustain the evolution of future LSI performance, we have started the research on the novel 3-dimension-structural devices and circuits.
  • 3. research on wireless integrated circuit (IC) based on information transmission
  • The ultracompact lightweight wireless IC is one of essential technologies for realizing the ubiquitous society which has the network available in anywhere, at anytime and from any surrounding items. For example, the IC tags for receiving information with reading function are getting close to the practical applications. In our laboratory, aiming at the automatic operating wireless IC with embedded power supply, we are systematically working on the following directions:
  • ①The electrical power generation and storage devices
  • ②Devices and circuits with Ultralow power consumption
  • ③Sensing devices
  • For all above subjects, We hope to conduct collaborative researches with companies interested in our research.
