Abstract
Ag and In co-doped SbTe phase change material (AgInSbTe) was used to fabricate nanopillar phase change memory. The AgInSbTe nanopillar type phase change device with 200 nm of diameter was fabricated by nanoimprint lithography and was reversibly changed between the resistances of 10(4) and 10(6) Omega by applying set/reset pulses using conducting atomic force microscopy. Due to the fast crystallization nature of AgInSbTe, the set operation of the device could be done with only 50 ns of set pulse. The fast crystallization nature of AgInSbTe is also responsible for the decrease in reset voltage of devices set with a short pulse.
