Industry and academia power on to develop nanoscale technology


Southampton University and Oxford Instruments have worked together to develop a range of processes which will be used to make nanoscale transistors.


The UK based organisations recently demonstrated the success of an industrial collaboration which is creating the cutting-edge nanotechnology needed for smaller, low power devices.


The ‘Knowledge Creation Partnership – From Funding to Results’ workshop at the University of Southampton, attracted a high level of interest, with talks by University researchers in nanotechnology and industrialists from Oxford Instruments Plasma Technology.


They described how the two organisations have partnered during a two year collaboration to develop nanotechnology tools. Combining the University’s knowledge and research with Oxford Instruments’ tools has already produced results, and these were presented by Peter Ashburn from the University, Mike Cooke, CTO at Oxford Instruments, and their colleagues.


between science and the consumer.” Frazer Anderson, Oxford Instruments Plasma Technology’s Business Development Director comments, “Through collaborations with some of the world’s leading scientists and institutions, companies like ours turn smart science into commercially successful products.”


Peter Ashburn, of the University’s Nano Research Group within ECS-Electronics and Computer Science is very positive about the collaboration, “Our University and Oxford Instruments have worked together to develop a range of processes for the company’s tools which will be used to make nanoscale transistors. These new plasma- based technologies provide etching and deposition functions on nanoscale materials and are being used in the Southampton Nanofabrication Centre, one of Europe’s leading multidisciplinary state-of- the-art cleanroom complexes.”


New SiC JFETs propel SemiSouth into high-end audio market


SemiSouth says its latest silicon carbide devices are 15% cheaper than conventional SiC JFETs and are particularly suited for high end audio amplifier designs demanding the best linearity performance and lowest distortion.


SemiSouth Laboratories has launched a new family of low cost SiC JFETS with very good linearity targeted at high-end audio applications.

“We recognise the importance of partnerships between the commercial and the academic sectors, in today’s highly competitive, fast moving and demanding global markets, and at Oxford Instruments we see businesses forming the bridge

The SJEP120R100A and SJEP120R063A are claimed to offer best–in-class distortion. Compatible with standard gate driver ICs, both versions feature a positive temperature coefficient for ease of paralleling; extremely fast switching with no ‘tail’ current at up to a maximum operating temperature of 150 0 C and a low RDS(on)max of 0.100Ω and 0.063Ω respectively. Devices are available in TO- 247 packages; the 100mΩ part is also available in die form for integration into modules.
