Characterization of low-temperature processed single-crystalline silicon thin-film transistor on glass

Single-crystalline silicon thin film on glass (cSOG) has been prepared using an "ion-cutting" based "layer-transfer" technique. Low-temperature processed thin-film transistors, fabricated both on cSOG and metal-induced laterally crystallized polycrystalline silicon, have been characterized and compared. The cSOG-based transistors performed comparatively better, exhibiting a significantly higher electron field-effect, mobility (similar to430 cm(2)/Vs), a steeper subthreshold slope and a lower leakage current that was also relatively insensitive to gate bias.
