Optimization of ALD Process for AZO Interlayer to Enhance Electrical Contact Properties of a-IGZO TFTs

초록

영어

Atomic layer deposition (ALD) process optimization of Al2O3-doped ZnO (AZO) interlayer (IL) inserted between channel and electrodes was held to improve electrical contact properties of amorphous In-Ga-Zn-O (a-IGZO) thin film transistors (TFTs). In particular, the modulation of the ALD supercycle duty and variations in Al₂O₃ injection cycles were investigated and optimized for their effects on contact properties during the deposition of the AZO IL. The use of alloy-AZO2 IL effectively improves overall device performance.
