Non-destructive characterisation of residual stresses for the silicon-on-sapphire technology. Every sapphire wafer for the fabrication of integrated circuits using the silicon-on-sapphire technology is worth more than a thousand dollars, and the cost grows exponentially with successive processing of circuitry. Early detection and prevention of wafer failure is therefore an economic and quality necessity.

Summary
Nanostructure Tailoring of Inorganic Membranes by Rapid Thermal Processing. This project aims to produce inorganic membranes with desired nanostructures using a Rapid Thermal Processing (RTP) technique for gas separation applications. The key concept of the research is that the RTP will be able to achieve thin-film membrane layer with a finer microstructure and pore size control without heat stress-induced cracking. RTP aims to deliver superior membrane performance with less than 10 per cent of ....Nanostructure Tailoring of Inorganic Membranes by Rapid Thermal Processing. This project aims to produce inorganic membranes with desired nanostructures using a Rapid Thermal Processing (RTP) technique for gas separation applications. The key concept of the research is that the RTP will be able to achieve thin-film membrane layer with a finer microstructure and pore size control without heat stress-induced cracking. RTP aims to deliver superior membrane performance with less than 10 per cent of the fabrication time compared to normal slow calcination. The outcomes of this new technology aims to make inorganic membranes a commercial reality and maximize the membrane manufacturing capability and productivity of petrochemcial, chemical and clean coal/energy industries.Read moreRead less
