A New Approach to Patterning Organic Electronics

Thin films composed of certain types of organic molecules, such as pentacene, can have electrical properties similar to those of conventional semiconductor materials such as silicon. These organic semiconductor films can be produced on the surface of plastics and glasses where silicon can not be used. This opens up a range of applications for organic electronics. But a major roadblock has been the inability to pattern organic films to the very small dimensions required for many potential applications. CNS researchers have solved this problem by developing a new optical technique that allows the patterning of multiple layers of organic semiconductors using the same optical lithography tools employed in patterning silicon wafers. This technique has the potential to revolutionize the way organic semiconductor devices are processed and to enable new applications of these novel electronic materials.
