摘要
Electrical properties of 20-30 nm gate oxides implanted with Si+ ions are investigated using MOS capacitors and transistors. The observed programming window can reach several volts and the devices exhibit good retention behavior. A first 256 k - nvSRAM is demonstrated showing a programming window >1 V for write pulses of 12 V/8 ms. (C) 2001 Elsevier Science B.V. All rights reserved.
