  • Patent number: 6890663
    Abstract: A process for forming an inorganic material layer pattern on a substrate. The process includes the steps of transferring an inorganic powder dispersed paste layer supported on a support film to the surface of the substrate to form the inorganic powder dispersed paste layer on the substrate; forming a resist film on the inorganic powder dispersed paste layer transferred to the surface of the substrate; exposing the resist film to light through a mask to form a latent image of a resist pattern; developing the exposed resist film to form the resist pattern; etching exposed portions of the inorganic powder dispersed paste layer to form an inorganic powder dispersed paste layer pattern corresponding to the resist pattern; and baking the pattern to form an inorganic material layer pattern.
