Fabrication of MOSFETs using low-temperature liquid-phase deposited oxide

Abstract

Low-temperature, high quality liquid-phase deposition (LPD) oxide was developed. The MOSFETs with such a new LPD oxide as gate insulators were investigated. The electrical characteristics, including threshold voltage of 2.1 Volts, peak effective mobility ( μ FE) of 580 cm 2/V·s, and subthreshold swing of 134 mV/decade, show the devices exhibit comparable performance to other low-temperature processed MOSFETs. This demonstrates that LPD oxide can be an suitable candidate for future gate insulators in low-temperature processed MOSFETs.
