Abstract:
1. A print module comprising: a substrate comprising an ink channel and an air vent; an ink jet semiconductor die comprising a plurality of ink apertures that extend through the ink jet semiconductor die and a die footprint; and a silicon interposer comprising an interposer footprint, a first silicon surface attached to the substrate, and a second silicon surface attached to the ink jet semiconductor die, wherein the second silicon surface is opposite the first silicon surface and the silicon interposer is positioned between the substrate and the ink jet semiconductor die, the silicon interposer further comprising a plurality of openings therethrough, wherein one of the openings through the silicon interposer comprises angled sidewalls, a first orifice having a first width at one of the first silicon surface and the silicon second surface, and a second orifice having a second width wider than the first width at the other of the first silicon surface and the second silicon surface, wherein the one of the openings provides an ink path from the substrate ink channel to the plurality of ink apertures through the ink jet semiconductor die, wherein the interposer footprint is less than or equal to the die footprint.
