Material deposition and laser annealing of metal oxide thin films for electronics fabricated at low temperature
… zinc oxide (AZO) and indium gallium zinc oxide (IGZO) thin films, a dual step fabrication process was studied in this research. Initially, an experimental programme was undertaken to deposit AZO and IGZO films by radio frequency (RF) magnetron sputtering with no external substrate heating and at …

Heterogeneously Integrated Impedance Based Biosensors
… noise of amorphous indium-gallium-zinc-oxide (a-IGZO) TFTs was characterised, and a TFT-based regulated cascade transimpedance amplifier was designed and simulated with the extracted device parameters. The a-IGZO TFT showed a comparable noise performance to the PMOS device in deep submicron …
