P-25: Top Gate Amorphous In-Ga-Zn-O Thin Film Transistors Fabricated on Soda-Lime-Silica Glass Substrates

This work presents a comparative analysis of top gate a‐IGZO TFTs fabricated on both soda‐lime‐silica glass and alkali‐free borosilicate glass. Low‐temperature ALD is selected for the deposition of gate dielectric to minimize a thermal stress. Comparing with TFTs on alkali‐free borosilicate glass, T...

description This work presents a comparative analysis of top gate a‐IGZO TFTs fabricated on both soda‐lime‐silica glass and alkali‐free borosilicate glass. Low‐temperature ALD is selected for the deposition of gate dielectric to minimize a thermal stress. Comparing with TFTs on alkali‐free borosilicate glass, TFTs with soda‐lime‐glass show similar threshold voltage and sub‐threshold swing, but slightly degraded effective mobility, stability and uniformity. The results of atomic force measurements are provided to explain the uniformity degradation.
