摘要： The nucleation efficiency of a thermal ink jet printhead is improved by forming a heater element with a planar surface. A heater resistor, polysilicon in a preferred embodiment, has an irregular surface which can trap gas or vapors in the cracks or crevices. When the heater resistor is pulsed, the nucleation temperature is reduced by these trapped vapors requiring an increase in electrical input to the resistors, thereby reducing efficiency. The invention recognizes that a heater resistor with a planar surface in contact with an ink layer results in a higher nucleation temperature and increased efficiency. In one embodiment, a phosphosilicate glass (PSG) is flowed directly onto the resistor surface forming a planarization layer. Subsequent deposition of tantalum substantially replicates the underlying topography creating a heater resistor with a smooth surface adjacent the ink.In a second embodiment, a diffusion layer which is conformal is formed on the resistor surface with the PSG layer formed on the oxide layer. The diffusion layer can be a pyrolytic CVD deposited silicon nitride or a thermally grown oxide layer. The PSG layer has a planarized surface to which the tantalum conforms.

摘要： The systems and methods of this invention allows for an electrical contact structure of the drop ejecting transducer in an inkjet printhead to be designed in such a way that the relatively thick electrical contact lines are not in the ink drop ejection path between the drop ejector transducer and the corresponding nozzle. Such a design thereby minimizes any visible defects due to misdirected satellite drops.

摘要： An improved method is disclosed for forming heater elements for an ink jet printhead. The resistance is more closely controlled by doping a central heater region which is formed relatively thinner than the heavily doped heater regions which are used as the gate and contact areas. The thinner central region can doped relatively heavy in order to more accurately adjust the heater resistance.In another embodiment, the thin layer is amorphous silicon rather than the polysilicon to increase the latitude of the energy input.

摘要： The efficiency of a thermal ink jet printhead is improved by providing a thermally grown field oxide layer and a deposited oxide layer, the two combined layers providing thermal insulation between a resistor layer and a silicon substrate. In a preferred embodiment, zirconium diboride is sputtered in the presence of oxygen to form a thin field oxide layer on a field oxide layer grown on the surface of the silicon substrate. At a predetermined time, during the sputtering process, oxygen is removed and the sputtering continues to form a conductive ZrB.sub.2 layer. The combined thickness of the two oxide layers provides the required thermal isolation between silicon substrate and heater resistor while the thermally grown field oxide layer enables the closer packing of resistor transistor drive circuits.

摘要： A thermal ink jet printhead is improved by providing a heater resistor which is mechanically isolated from overlying nitride and tantalum layers by growing a thin buffer oxide layer on the surface of the resistor heater layer. The introduction of the buffer oxide layer permits a thinner nitride layer which, in turn, reduces electrical resistance changes which would otherwise be introduced into the resistor arrays by mechanical stress after the nitride layer is deposited.

摘要： An ink jet printhead has improved resistance to the corrosive effects of ink by coating the surface of a photo-imageable polymer with an ink resistant film. In one described embodiment, a thermal ink jet element is formed by bonding together a channel plate and a heater plate. Resistors and electrical connections are formed in the heater plate. A polyimide layer is formed so as to overlie the heater plate to protect the electrical elements while providing pit structure for the heater and for ink flow bypass. A tantalum film is formed on the surface of the polyimide layer to protect the layer from the effects of corrosive ink. In another embodiment, the ink resistant film is amorphous carbon or silicon nitride.
