摘要

The tungsten nanocrystals (W-NCs) memories fabricated by W/Si dual-sputtering and O₂ and N₂O annealing process were investigated. Significant W-NCs dots were formed by N₂O annealing and proved by the energy dispersive X-ray spectrometer (EDX) analysis. Superior electrical properties of W-NCs memories were optimized for 20/30 W/Si dual-sputtered ratio, 10-15 nm blocking oxide thickness and N₂O annealing at 950 °C. A pronounced capacitance-voltage hysteresis was observed with a memory window of 6.5 V under +9/-9 V sweeping.
