The versatile memory characteristics on the Film Surfaces of NewPolyimides |
| 초록 |
We have fabricated electrically programmable memory devices with thermally and dimensionally stable 6F-2TPA PI Films and investigated their switching characteristics and reliability. The 6F-2TPA PI films exhibit versatile memory characteristics that depend on the film thickness. All the PI films are initially present in the OFF state. The PI films with a thickness of ＞15 to ＜100 nm exhibit excellent write-once-read-many-times (WORM) (i.e. fuse-type) memory characteristics with and without polarity depending on the thickness. The WORM memory devices are electrically stable, even in air ambient, for a very long time. The devices’ ON/OFF current ratio is high, up to 1010. On the other hand, the 100 nm thick PI films exhibit excellent dynamic random access memory (DRAM) characteristics with polarity. The ON/OFF current ratio of the DRAM devices is as high as 1011. |
