photostrukturierbare coatings based on a hydrogen silsesquioxanharzes

摘要

The present invention relates to a method of forming patterned coatings on substrates, especially electronic devices, by negative resist techniques. The method comprises applying a preceramic coating comprising hydrogen silsesquioxane resin and an initiator onto the substrate and then radiating a selected region of the coating for a time sufficient to cure the resin. The uncured coating is then rinsed away leaving the patterned coating.
