摘要： A porous foam based ink containment system is provided with grooves defined in the exterior portion thereof, for storing ink, while preventing ink leakage from the ink-jet pen. The grooves provide passageways to allow air diffused throughout the ink and trapped air bubbles within the foam to expand and move to the atmosphere. An atmospheric vent is in fluid communication with at least one of the grooves.

摘要： A monolithic inkjet printhead is formed using single-side fabrication processes. Printing elements and feed channels are formed by processes working from a top of the die. During formation of the printing elements filler material is applied to the feed channel. Such material is later removed by an anisotropic etch. Such etchant works from the top surface and a side edge of the substrate. The single-side fabrication process is distinguished from fabrication processes that work from a bottom of a die to form the feed channel and fill channels and work from a top of the die to form printing elements.

摘要： An electrical interconnect for an inkjet printhead comprising an ink-ejecting semiconductor die is described. The ink-ejecting die further comprises a substrate having an opposing upper surface, lower surface, and a thin film stack. The upper surface of the substrate is beveled on at least one edge such that a lower portion of the bevel is below an upper portion of the bevel. A conductive material trace is disposed on top of at least a portion of the upper surface and the thin film stack and on the bevel towards the lower portion of the bevel. An electrical conductor is coupled to the conductive material trace at a predetermined location below the upper portion of the bevel. In a preferred embodiment of the current invention, the conductive material trace is substantially below the surface of the printhead thereby creating a robust printhead having several advantages including but not limited to: (1) electrical interconnects that are solidified in an encapsulant and therefore protected from chemical etching of the ink and vibrational/physical forces generated by the printer, (2) minimized die to printing medium distance and (3) minimized ESD effects on the beveled die.

摘要： A refill channel for multiple rows of nozzles is formed in a silicon die by thinning the die in the vicinity of the rows, then etching respective trenches within the thinned portion of the die. Monolithic architectures including such trenches are achieved for existing inkjet nozzle geometries having close row spacing.
