Fabrication Of Nano-Scale Ge-Sb-Te Phase Change Memory Cell Using Tungsten Nano-Patterns Deposited By The Focus Ion Beam System As Hard Mask
Nano-scale Tungsten patterns were created within a scanning electron microscope through electron-beam-induced deposition. The tungsten patterns were used as a reactive ion etching hard mask to fabricate phase change material nanoparticle arrays. The diameter of the phase change nanoscale structure is 38.5 nm. The nanoprobes were used to measure the electrical characteristics of the Ge2Sb2Te5 nanopillar. A 2 V pulse, (pulse width 28 ns, pulse trailing 3 ns) was applied to the initially crystalline phase GST nano-pillar to bring about its amorphization. The amorphous state was brought back to crystalline state by applying 2.3 V set pulse (pulse width 50 ns).
