Organic semiconductor-based devices such as thin film transistors, organic light emitting devices and solar cells have potential in low cost electronic and optoelectronic applications. One end of the contact spring is conductively connected to the first relay contact and another free end of the contact spring closes or interrupts the electric circuit in a first end position of the contact spring and in a second end position of the contact spring, respectively. In embodiments, channel regions and gate electrode materials are aligned to edges of segregated regions within the DSA material.
