Abstract
An ink jet printhead composed of substantially two identical parts and method of batch fabricating the parts. Each part has V-grooves anisotropically etched between a linear array of heating elements having selectively addressable electrodes which are parallel to each other. The grooved structures of the parts permit them to be mated face-to-face, so that they are automatically self-aligned by the inter-meshing of the lands containing the heating elements on one part with the grooves of the other part. A pair of parts may be used as a printhead for a carriage type ink jet printer or a plurality of parts may be assembled for a pagewidth printer. The pagewidth printhead is assembled by offsetting the first two parts a selected number of grooves when they are mated so that the subsequently added adjacent parts abut each other and yet are self-aligned with the confronting parts.
