Abstract
An organic semiconductor element is provided which has the controlled crystalline state of a vapor-deposited pentacene layer and a high mobility with low voltage driving. The organic semiconductor element is formed by providing a gate electrodeon the surface of a substrate, providing thereon a gate insulating layer, providing on the surface of the gate insulating layeran island-shaped protrusion layerhaving dispersed and island-shaped protrusions with a low surface energy, providing on the island-shaped protrusion layera source electrodeand a drain electrodewith a distance therebetween, providing thereon an organic semiconductor layerin contact with the island-shaped protrusion layerand both electrodesand, and further providing a protective filmon the organic semiconductor layer
