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.

摘要： An ink jet cartridge assembly for use in an ink jet printer has a body with at least one inner ink chamber. A printhead is carried by the body and has a plurality of ink jetting orifices in fluid communication with the ink chamber. A tape automated bonding circuit carried by the body includes a flexible tape and a plurality of electrical traces. The flexible tape includes a chip window with a peripheral edge. The printhead is disposed within the chip window at a distance from the peripheral edge. Each electrical trace has a bottom side adjacent the body, a substrate held portion carried by the flexible tape, a free trace portion extending between the peripheral edge of the chip window and the printhead, and a printhead held portion connected with the printhead. The tape automated bonding circuit further includes a photoimagable coating which covers the bottom side of each electrical trace on all of the substrate held portion and the free trace portion, but does not cover the printhead held portion.

摘要： The invention provides an improved method for grit blasting slots in a silicon wafer. The method includes, providing a silicon wafer having a first surface and a second surface, the first surface containing resistive, conductive and insulative layers defining individual semiconductor components, applying a first substantially permanent non-water soluble layer selected from silane, photoresist materials and a combination of a silane layer and a photoresist layer to the first surface of the wafer to provide a first substantially permanent layer thereon, applying a water-soluble protective material to the first layer to provide a second layer, grit blasting slots in the wafer corresponding to the individual semiconductor components, and subsequently, removing the water-soluble protective layer from the wafer. The protective layer provides enhanced protection for the electrical components on a silicon wafer during a grit blasting process so that a higher yield of useable semiconductor chips may be made.
