Presentation Summary

  • A novel, high target utilisation sputtering (HiTUS) system has been used to produce a diverse range of metal oxide materials for transparent electronics including dielectrics and both p- and n-type semiconductors
  • The HiTUS system gives greater control of material properties compared with magnetron sputtering
  • This improved control is exemplified by the deposition of a new phase of amorphous hafnium oxide - cubic-like amorphous hafnium oxide - which has a fully amorphous structure and a dielectric constant of 30, and is a significant improvement beyond the state-of-the-art
  • It will be demonstrated that these materials can be incorporated into both thin film transistors and solar cells

Company Profile (University of Cambridge, Dept of Engineering)

University of Cambridge, Dept of Engineering logo
Cambridge University Engineering Department, which was rated as a 5* Department in the last Research Assessment Exercise, has been carrying out research in thin film transistors based on amorphous silicon and other inorganic materials for more than ten years. It has a state-of-the-art clean facility within the Centre for Advanced Photonics and Electronics. This includes 160 m2 of Class 10,000 laboratories which houses a range of deposition systems for producing a diverse range of materials including metallic thin films, amorphous silicon, high-k dielectrics, carbon nanotubes and silicon nanowires. There is a further 140 m2 of Class 1,000 laboratories which includes processing facilities for 1 µm photolithography and nanoparticle-polymer composite processing. Finally, there is 140 m2 of Class 100 laboratories which includes a rapid thermal annealer, deep reactive ion etch system, liquid crystal processing facility, 0.5 µm double-sided mask aligner and an e-beam lithography system.
