Electrics and Electronic Engineering Research Centre

Microelectronics Research Group

The Microelectronics Research Group conducts internationally leading microelectronics research. 

Currently, researchers from the Microelectronics Research Group are investigating new technologies and materials. Members from the Group are also exploring ‘show-stoppers’ for optimizing digital/analogue circuits.

The work the Microelectronics Research Group undertakes can be broadly divided into the following three areas:

  • New materials and devices for future microelectronic industry: the research team are investigating high-mobility channel semiconductors (Ge and III-V), resistive switching random access memory (ReRAM), III-Nitride-based devices, and 3D electronic devices 
  • Qualification, modelling, and aging prediction: members of the Group are developing new models for predicting lifetime induced by negative bias temperature instability (NBTI) and hot carriers. The researchers are also working to improve the standard industrial test procedure
  • New characterisation techniques: the Group has developed novel measurement techniques. These techniques are implemented at research and development centres, such as IMEC, and on the industrial standard test equipment, such as Keithley Instruments

In the latest research assessment (Research Excellence Framework 2014), 100% of the Microelectronics Research Group’s research outputs were ranked as internationally excellent.

In addition to this success, the Group regularly publishes its results in high-impact journals and flagship conferences, such as: the Institute of Electrical Electronics Engineers (IEEE) Transactions, International Electron Device Meetings (IEDM), and the Symposium of VLSI Technology. Since 2007, the Group has co-authored 11 IEDM papers. This is more than any other university in the UK.

The Microelectronics Research Group also has an exceptional track record with regards to the quality of its PhD students’ theses. Over the last 20 years, each student has, on average, published 4.5 journal papers. External examiners have also recommended several theses from the Group for Faculty Awards and a PhD student won the Prestigious Innovation Award in the Academia, which was granted by the Malaysian Government.

The research that the Microelectronics Research Group conducts is supported by grants from the UK Engineering and Physical Science Research Council (EPSRC). Recently, the Group was awarded two grants from the EPSRC – one for research into the impact of device variability on circuits and one for examining resistive-switching random access memories. For these projects, researchers from the Group are working in collaboration with Arm Holding, Cambridge Silicon Radio (CSR), the University of Cambridge, and an IMEC-based industrial consortium, which has members from Intel and Samsung.

In the future, the Microelectronics Research Group intends to develop novel qualification techniques and models that will go on to become the new industry standards. The Group also plans to break into new research areas, such as, InGaAs based nanometer MOSFETs, and III-Nitride-based devices.

Case studies

Measuring electron mobility is essential for evaluating new materials and processes in the semiconductor industry but measurement has historically been expensive, unreliable and inefficient. The Microelectronics Research Group has developed a technique which overcomes these issues.
