WHAT IS MATERIALS CHEMISTRY?
MATERIALS CHEMISTRY IN POWER ELECTRONICS
NXP Semiconductors are a UK organisation who work with gallium nitride, GaN, a material which is proving to have fundamental capabilities that go far beyond those of silicon. For the same resistance, chips can be five times smaller or can handle a maximum voltage three times higher than is currently possible. GaN chips can operate at high temperatures – up to 200°C – an important consideration in the development of power electronics for big business.
Through the KCMC, NXP Semiconductors have worked with materials chemists at the University of Liverpool. Julian Humphreys, Vice President and General Manager Power MOS Business, NXP Semiconductors and Director and Country Manager for NXP Semiconductors UK Ltd, describes role of the collaboration.
“We wanted to look at atomic layer deposition (ALD) but didn’t have the state-of-the-art equipment or technical capability. Using the labs at Liverpool worked really well – they’re a UK leader in ALD. Without this collaboration, we wouldn’t have been able to have performed these proof-of-concept experiments. The first results are looking really encouraging and we’re hoping to produce a commercial product which can deliver what the theory suggests the material is capable of.”
