Latest Patents

One of Donson's latest patents is a method for conditioning an organic polymeric material. This invention focuses on the ability of certain organic polymeric materials to reversibly accept or donate electrons from a reducing entity. The redox sites in the polymer accept electrons, leading to a change in the properties of the polymer. This change is beneficial for modifying or etching the polymeric material. The process involves incorporating metallic seeds into the material at a controlled depth through the interaction of cations of the metals with the redox sites in the polymer. This results in the reduction of the cations to form neutral metallic seeds. Furthermore, exposure of the polymeric material containing the seeds to an electroless bath allows for further deposition of metal, which adheres well to the polymeric material. The etching process can be performed due to an increase in the solubility of the polymer in aprotic solvents when its redox sites have accepted electrons. This increased solubility enables the etching of openings in specific areas of the polymeric material that have been reduced, while leaving other areas unchanged.

Another significant patent by Donson involves providing circuit lines on a substrate with a non-planar surface. This process includes applying a layer of photoresist material to the substrate, selectively screen printing on non-planar areas, photoprocessing the photoresist layer, and ultimately providing an electrical conductive pattern on the substrate.
