Abstract
【解決手段】本発明はメモリセルとして利用できる選択的導電性有機半導体(例えば、ポリマー)デバイスを提供する。導電性ポリマー(22)を含むポリマー溶液は導電性電極(26)に関してセルフアセンブルする。最短の導電性経路を実現できるように、処理はセルフアセンブルを行うことができる。方法において、導電面(26)に導電性ポリマー(23)の濃縮液を堆積し、熱と、任意に真空を与えて、導電性ポリマー(22)を有機半導体にセルフアセンブルさせる。有機半導体は、2つもしくはそれ以上の電極を有する構造を形成し、一方で各電極間のパッシブデバイスに沿って有機半導体を利用して、シングル及びマルチセルメモリデバイス内に用いられてよい。
