In this study, the synthesis of thermally and mechanically stable polyimide, (hexafluoroisopropylidenediphthalimide-4-hydroxytriphenylamine) (6F-HTPA PI) was successful and the nonvolatile memory devices based on a high performance polyimide, 6F-HTPA PI, were fabricated with a simple conventional solution coating process. The 6F-HTPA PI film exhibits excellent write-once-read-many-times (WORM) memory characteristics with and without polarity depending on the thickness and bottom electrode with a high ON/OFF current ratio of up to 106 and a long retention time in both ON and OFF states.1 These properties open up the possibility of the low-cost mass production of high density and very stable digital nonvolatile WORM memory devices. |
