- the properties of these materials in these applications which make them attractive are their coefficients of thermal expansion and their thermal stability.
- Alumino or Borosilicate glasses are currently used as substrates for silicon in devices such as solar cells and thin film transistors for displays, due to their matched thermal expansion and stability up to about 600 °C and relatively low cost.
- the performance of such devices is limited by the maximum processing temperature at which the device can be produced, and this also affects the cost.
- An increase in the refractoriness (i.e. thermal stability) of the substrate would enable higher temperature processing with concomitant device performance enhancement and/or cost reduction.
- Silicon is currently used as a substrate for silicon in microelectronic applications, e.g. silicon on insulator (SOI).
