A semiconductor device having a conducting path of novel structure, which is formed from an organic semiconductor molecule material and shows a high mobility, and method for manufacturing such a semiconductor device. By a functional group at both ends of an organic semiconductor molecule (9) such as 4,4’- biphenyldithiol, fine particles (8) made of a conductor such as Au or a semiconductor and organic semiconductor molecules (9) are alternately linked, thereby forming a conducting path of network structure wherein conducting paths within the fine particles (8) are two-dimensionally or three-dimensionally linked with conducting paths within the organic semiconductor molecules (9). In this conducting path, there occurs no move of electrons between molecules and the mobility is not restricted by such move of electrons between molecules. Consequently, the mobility of the conducting path along the main chain of the organic semiconductor molecule (which is in the direction of molecular axis), for example the high mobility of non-localized ? electrons within molecule can be utilized to the maximum. |
