A group of methods to pattern conductive organic polymer layers on a support is offered on the Yet2.com Web site, featuring technologies sought and available for license in a variety of industries. Conductive patterns reportedly can be generated by several methods: heating selected areas of the polymer layer; using differential light sensitivity; selective removal of the conductive coating using a developer; or by using a printable conductive organic polymer paste.
The electroconductive pattern thus obtained can be used, for example, as an electronic circuit for making an electric or semiconductor device. According to the site, the feasibility of the proposed methods has been proven in prototypes and the use of conductive paste for patterning by serigraphy is commercialized. This technology is supported by eight U.S. patents. The most recent year of issue is 2005. For more information, visit: www.yet2.com.
