Abstract
A method of removing an organic, preferably polymeric, light-emitting material (4) from defined areas of a substrate (1) comprises the steps of arranging a shadow mask (5) to overlie the organic material other than in the defined areas, and applying a beam of ions (7) to the defined areas through the mask. The method is useful in forming organic light-emitting diode arrays.
Claims20
A method of removing an organic light-emitting material from defined areas of a substrate comprising the steps of arranging a shadow mask to contact the substrate and overlie the organic material other than in the defined areas, at least one of the mask and the substrate having recesses in its surface facing the other of the mask and the substrate, and applying a beam of ions to the defined areas through the mask.
