    摘要: The present disclosure provides a method of cleaning a semiconductor substrate after a DRIE etch process, wherein residue from the DRIE process is removed without damaging the substrate. The process may include contacting the micro-fluid ejection head with an aqueous solution of TMAH, stripping a photoresist etch mask from the micro-fluid ejection head, and dissolving a passivating coating from the substrate. Then the substrate may be contacted with an acidic solution. The method may further include rinsing and drying the substrate.

    摘要: The invention provides a method for improving adhesion between a polymeric planarizing film and a semiconductor chip surface. The method includes deposition resistive, conductive and/or insulative materials to a seimconductor chip surface to provide a semiconductor chip for an ink jet printer. The chip surface is treated with a dry etch process under an oxygen atmosphere for a period of time and under conditions sufficient to activate the surface of the chip. A polymeric planarizing film is applied to the activated surface of the semiconductor chip. As a result of the dry etch process, adhesion of the planarizing film is increased over adhesion between the planarizing film and a semiconductor surface in the absence of the dry etch treatment of the chip surface.

    摘要: The invention provides a method for making ink feed vias in semiconductor silicon substrate chips for an ink jet printhead and ink jet printheads containing silicon chips made by the method. The method includes applying a first photoresist material to a first surface side of the chip. The first photoresist material is patterned and developed to define at least one ink via location therein. An etch stop material is applied to a second surface side of the chip. At least one ink via is anisotropically etched with a dry etch process through the thickness of the silicon chip up to the etch stop layer from the first surface side of the chip. 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: A method of tape automated bonding a heater chip of an ink jet printer to a flexible circuit includes the step of attaching an electrically conductive bonding pad to a first portion of a surface of the heater chip. A mask is applied to a second portion of the surface of the heater chip. An exposed surface of the bonding pad is chemical dry etched for a predetermined time period to thereby remove contaminants from the etched exposed surface. The chemical dry etching is terminated at an end of the predetermined time period such that substantially none of the bonding pad is removed. Lastly, the flexible circuit is electrically connected to the etched exposed surface.
