摘要： The invention provides a method for making ink feed vias (14) in semiconductor silicon substrate chips (10) for an ink jet printhead (26) and ink jet printheads containing silicon chips made by the method. The method includes applying an etch stop layer to a first surface of the silicon chip having a thickness ranging from about 300 to 800 microns, dry etching individual ink vias through the thickness of the silicon chip up to the etch stop layer from a surface opposite the first surface and forming holes in the etch stop layer to individually fluidly connect with the ink vias using a mechanical technique. Substantially vertical wall vias are etched through the thickness of the silicon chip using the method. As opposed to conventional ink via formation techniques, the method significantly improves the throughput of silicon chip and reduces losses due to chip breakage and cracking. The resulting chips are more reliable for long term printhead use.

摘要： An apparatus and method is provided for compensating for the effects of thermally induced droplet size variations in ink-jet printers. The apparatus includes a temperature determination unit (28) for determining the temperature of the print head, and a halftone adjustment unit (18) configured to receive the print head (32) temperature from the temperature determination unit (28) and to receive image data in the form of nominal halftone values. The adjustment unit (18) can increase or decrease the number of dots to be printed, and thereby compensate for droplet size variations, either by adjusting the nominal halftone values based upon the temperature or by adjusting a threshold array based upon the temperature. The temperature determination unit (28) can predict the print head (32) temperature by counting the number of dots to be printed by counting the binary halftone values fed to the swath memory.

摘要： The present invention is directed toward an improved heater chip for an ink jet printer. The heater chip has a diamond-like-carbon (12) coating that functions as the cavitation and passivation layers of the heating elements (10) on the heater chip. To improve the efficiency of the heater chip, the diamond-like-carbon coating is surrounded by a material that has a lower thermal conductivity than diamond. This surrounding layer limits thermal diffusion from the heating elements into the heater chip. A smoothing layer of tantalum is deposited over the diamond-like-carbon layer to insure that vaporization of the ink occurs at the ink's superheat limit. The diamond-like-carbon layer is preferably less than 8700 Angstroms in thickness such that less than 1 microjoule of energy is required to expel of ink droplet having a mass between 2-4 nanograms.
