Abstract: The formation of substrate electrical connections on thin film heads is one source of resulting surface topography. In accordance with one implementation, such topography can be reduced by a process that includes depositing a first layer of basecoat, creating electrical recessed vias in one or more plating processes, and depositing a second layer of basecoat on top of the electrical vias and on top of the first layer of basecoat. In one implementation, the first and second layers of basecoat have a combined height that is substantially equal to the height of the electrical recessed vias. In one implementation, the resulting topographical features are small enough that they can be planarized without creating a lack of uniformity in the total basecoat thickness across the wafer.

The circuitry for the different modules is initially formed on the single meta-module. Each module will have one or more component areas in which the circuitry is formed. A metallic structure is formed on or in the substrate for each component area to be shielded. A single body, such as an overmold body, is then formed over all of the modules on the meta-module. At least a portion of the metallic structure for each component area to be shielded is then exposed through the body by a cutting, drilling, or like operation. Next, an electromagnetic shield material is applied to the exterior surface of the body of each of the component areas to be shielded and in contact with the exposed portion of the metallic structures.
