摘要： An integrated nozzle plate having a heater chip and nozzles, firing chambers and channels formed from several layers of resist material affixed to the heater chip. The nozzles, firing chambers and channels are formed in the resist material using a photolithographic method. The photolithographic method involves placing a negative resist layer directly on a silicon wafer heater chip. A protective layer is then placed on top of the negative resist layer to act as a mask. A positive resist layer is then placed on top of the protective layer. A first mask is placed on the positive resist layer. The integrated nozzle plate is then exposed to ultraviolet light and the positive resist layer is developed. The protective layer not covered by the positive resist layer is removed and a second negative resist layer is deposited thereon. A second mask is placed on the second negative resist layer. The first and second negative resist layers are exposed to ultraviolet light and the negative resist layers are developed. The resulting integrated nozzle plate is then mounted to a print head, connected to an ink reservoir and placed in an inkjet printer for use.

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.

摘要： The invention provides a method for making thin film metal oxide actuator device. According to the method a first conductive layer is deposited on a silicon substrate. Next a thin film metal oxide layer is deposited on the first conductive layer. A negative photoresist material is applied to the metal oxide layer to provide a photoresist layer. The photoresist layer is patterned using light radiation energy and developed to provide one or more exposed portions of the metal oxide layer. The photoresist layer is etched with a reactive ion plasma sufficient to remove the photoresist layer and the metal oxide layer under the photoresist layer from the first conductive layer leaving the one or more exposed portions of metal oxide layer on the first conductive layer. A second conductive layer is attached to the metal oxide layer to provide a thin film metal oxide actuator device. The method may be practiced without the use of more dangerous or hazardous wet chemical etching techniques which may provide undesirable undercutting of the metal oxide layers or may leave contaminants on the patterned metal oxide layers.
