Novel WORM Memory Devices based on a thermally, dimensionally and chemically stable polyimides with carbazole Moieties |
| 초록 |
A series of soluble poly(amic acid) precursors were prepared from a new carbzole-containing monomer, 3,3’-bis[9-carbazole(ethyloxy)biphenyl]-4,4’-diamine (HAB-CBZ) by polycondensation with four different aromatic dianhydrides: PMDA, BPDA, ODPA, and DSDA. From the precursors, nanoscale thin films of polyimides were prepared by spin-coating and subsequent thermal imidization. All the PIs exhibited excellent thermal and dimensional stability. In particular, the PIs based on the PMDA and BPDA units revealed excellent chemical resistance to organic solvents which are required for the fabrication of high performance memory devices in three-dimensionally multi-stack structure. Devices fabricated with nanoscale thin PI films exhibited excellent unipolar write-once-readmany-times (WORM) memory behavior with a high ON/OFF current ratio of up to 1010. The active PI films were found to operate at 2.2-3.3V, depending on the chemical structures. |
