Thin-Film ZnO Charge-Trapping Memory Cell Grown in a Single ALD Step
A thin-film ZnO-based single-transistor memory cell with a gate stack deposited in a single atomic layer deposition step is demonstrated. Thin-film ZnO is used as channel material and charge-trapping layer for the first time. The extracted mobility and subthreshold slope of the thin-film device are...

| description | A thin-film ZnO-based single-transistor memory cell with a gate stack deposited in a single atomic layer deposition step is demonstrated. Thin-film ZnO is used as channel material and charge-trapping layer for the first time. The extracted mobility and subthreshold slope of the thin-film device are 23 cm 2 /V·s and 720 mV/dec, respectively. The memory effect is verified by a 2.35-V hysteresis in the I drain - V gate curve. Physics-based TCAD simulations show very good agreement with the experimental results providing insight to the charge-trapping physics. |
