Abstract: A printer head member having ultrafine grooves of high density and high precision. In one or more embodiments of the invention, a flat plate made of ceramics, glass, silicon or the like is bonded and integrated to a partition wall made of a powder of ceramics, glass, silicon or the like, obtained by a molding process. The mold used for obtaining the partition includes ultrafine grooves that conform to the shape of a partition. In another embodiment of the invention, a member for passage having high density and high precision is obtained by a molding process. A flat plate made of ceramics, glass, silicon or the like is bonded and integrated to a partition wall made of a powder of ceramics, glass, silicon or the like, using a molding die having one or more fine grooves for forming one or more partition walls, wherein at least a passage is formed between the partition walls.

Abstract: A plasma display substrate comprising a rear plate and a plurality of partitions for forming display cells between every two adjacent partitions on one of the surfaces of the rear plate, wherein the partitions are molded independently of the rear plate with the mixture of ceramic or glass powder and a binder inclusive of organic additives and solvents are formed in a desired shape and a desired disposition on one of the surfaces of the rear plate made of ceramics or glass, and integrally joined to the rear plate. According to the substrate, the display cells have improved dimensional accuracy, particularly, the partitions having highly accurate flat side surfaces with no deformation and having a predetermined height can be formed easily. This disclosure also provides a method of producing the same.
