    Abstract: PROBLEM TO BE SOLVED: To provide a method for forming opaque rib structures for a plasma address type liquid crystal display which does not leave opaque material films between the rib structures by using a micromolding technique. SOLUTION: A temporary mask is formed in the plural portions of a substrate 204 surface. A glass paste layer having curable material and at least one pigment compounded with the inside thereof is deposited to cover the substrate 204 and the temporary mask, by which the rib structures consisting of the glass paste are micromolded on the surface of the substrate 204 existing in the regions between the masked portions. Any residual paste material layers existing on the temporary mask are removed and the temporary mask is removed from the substrate 204. The substrate 204 having the micromolded rib structures thereon is then baked.

    Abstract: Optical waveguide paths are formed under the surface of a glass substrate by a method comprising (a) forming by ion-exchange a dopant ion path on a first substrate surface, (b) applying an electrode to the second surface, (c) contacting the first surface with a molten salt bath, and (d) applying an electrical field across the substrate to drive the dopant ions deeper into the substrate. The apparatus comprises means (37) for supporting the substrate (13') such that the first substrate surface (17') is in contact with the molten salt bath (10'). A porous electrode (19') is disposed on the second surface (18') of the substrate. Means (23') applies a voltage to the porous electrode and the bath to create the electrical field. The substrate supporting means (37) includes a planar conductive surface (42) for contacting the porous electrode (19'). A groove (41) extends around the periphery of the conductive surface, and means (40, 43) evacuates the groove and removes oxygen from porous electrode (19'). A glass insulating ring (35) can be affixed to the periphery of the second surface (18') to prevent salts from the bath (10') from migrating up the side surfaces of the substrate by capillary action.
