Abstract
A low-cost and efficient process producing improved organic electronic devices such as transistors that may be used in a variety of applications is described. The applications may include radio frequency identification (RFID) devices, displays and the like. In one embodiment, the improved process is implemented by flash annealing a substrate with an energy having wavelengths ranging from about 250 nm to about 1100 nm or higher. In this flash annealing process energy having wavelengths from about 250 nm to about 350 nm or higher is substantially prevented from irradiating the substrate.
Claims8
A method of manufacturing an organic transistor, comprising:
- providing a substrate;
- forming a gate electrode on the substrate;
- selectively forming nanoparticle ink on the gate electrode to form posts;
- selectively forming a dielectric material on the substrate;
- flash annealing the nanoparticle ink with an energy having wavelengths ranging from about 250 nm to about 1100 nm or higher, wherein the flash annealing comprises preventing energy having wavelengths from about 250 nm to about 350 nm from irradiating the nanoparticle ink, and
- wherein the flash annealing cures the nanoparticle ink and simultaneously forms vias in the dielectric layer above the posts;
- forming source/drain electrodes in electrical communication with the posts;
- and
- forming an organic semiconductor layer on the substrate.
