Preparing multilayer ceramic (MLC) modules by injection molding a mixture of a fine particulate such as alumina and a binder into a mold containing predesigned ridges and pins. The product is a green body layer of ceramic containing grooves and vias that is thereafter metallized with a conductive paste and laminated to other like layers of ceramic. Solvent extraction of the binder and sintering of the MLC forms the module.
