1. A semiconductor device comprising an organic semiconductor thin film formed by a method including the steps of:

  • preparing an organic semiconductor compound including an amino group;

    preparing a long chain hydrocarbon including a carboxyl group which can be bonded to said amino group;

    bonding said organic semiconductor compound including said amino group to said long chain hydrocarbon including said carboxyl group for making said semiconductor compound to be dissolved in an organic solvent;

    making an organic solution by dissolving said organic semiconductor compound combined with said long chain hydrocarbon in said organic solvent;

    dropping said organic solution in an appropriate liquid for forming a layer of said organic solution on the surface of said liquid;

    removing said organic solvent from said layer of said organic solution for forming a layer of the combination of said organic semiconductor compound and said long chain hydrocarbon on the surface of the liquid;

    depositing said layer of the combination of said organic semiconductor compound and said long chain hydrocarbon on the surface of a substrate; and

    removing said long chain hydrocarbon from the layer of said combination for forming an organic semiconductor thin film consisting of said organic semiconductor compound including the amino group on the surface of said substrate.
