Abstract
The present invention provides a process for preparing a patterned organic layer from an unpatterned water-soluble organic layer. The process includes the steps of: imagewise exposing to radiation a photosensitive unpatterned water-soluble organic layer deposited on an organic semiconducting material, a metal or an insulator layer, to produce an imagewise exposed organic layer having exposed and unexposed regions; and contacting the imagewise exposed organic layer and an aqueous-based developer to selectively remove the unexposed regions thereby producing the patterned organic layer. The present invention also provides an improved for fabricating an electronic device having a patterned organic layer adjacent to an organic semiconducting material, metal or insulator layer.
