New basic Si devices beyond the CMOS scaling
 |
|
The development of microelectronics has been so far largely dominated by CMOS scaling. But this approach is now facing physical and economics limits, so that most of the industries of microelectronics and related sectors are pushing other routes for their evolution. Novel back-end solutions to implement complex devices such as memories, sensors, and energy harvesting on CMOS chips are very actively pursued. New opportunities also come from the area of Si photonics and photovoltaics. In our group we are studying these opportunities in a few, well defined areas. Our focus is on device characterization and physical modeling, in strong sinergy with Industry. In particular, one of us (S. Lombardo) is collaborating with temporary address at STMicroelectronics to better connect the basic research aspects with the application needs. |

Si based Sensors
 |
Over the past few years there has been a growing interest in creating microbiosensors integrated within microelectronic circuits. It led the research to find innovative devices that could satisfy both the needs of mass production and accurate analysis. Si-based materials could allow, among the other advantages, the device miniaturization and the possibility to integrate the electronics and/or photoelectronics needed for detection on the same chip. Our research is focused on the demonstration of transduction mechanisms providing electrical or optical output and suitable for Si-compatible signal processing.

Novel Concepts for Memories
 |
The aggressive scaling of the Flash devices is pushing this technology towards a ‘‘wall’’ made of numerous technological key issues, for both stand-alone and embedded non-volatile memories (NVMs). Cost is the number one, key issue. In this activity new opportunities, based on the discrete storage node concept and on the resistive switching mechanism for back-end solutions are explored.

Si based Materials for Photovoltaics
 |
Photovoltaics is facing a huge growth thanks to the increasing interest towards renewable energies, due to the need at the worldwide level to reduce carbon emission for energy production. Photovoltaics is also a major technology for energy harvesting, to power novel generation of microsystems, systems on chip (SoC) and systems in package (SiP) devices. The dominant PV technology is silicon based, being non-polluting, easily available, a very strong covalent material (necessary for PV module reliability), and with a highly developed technology and understanding. In this activity we explore novel Si based materials to realize new generations of photovoltaic devices. Contact person: Rosaria Puglisi For further information dowload these files: Photovoltaics
