摘要： A system and method of operation for a piezoelectric transducer is described which utilizes a mesa structure interposed between a piezoelectric material element and a chamber diaphragm. The system can be used as a sensor where a net motion to the diaphragm causes a net charge equal to the sum of the charges on each piezoelectric diaphragm. Alternatively, the system can be used as an actuator wherein an applied voltage causes movement of the piezoelectric transducer and the chamber diaphragm.

摘要： A thermal ink-jet printhead includes ejectors wherein a heating surface is disposed within a channel retaining liquid ink. The heating element within each ejector includes a converter for converting applied electrical energy to heat energy, and a distributor, for distributing the heat energy over a portion of the heating surface. The structure of the heating element allows the effective area of nucleation within the heating area, the size of which directly affects the volume of the ejected liquid ink droplet, to be varied with voltage and/or pulse width.

摘要： In an ejector for a thermal ink-jet printhead, a heating element exposing an area to liquid ink in the printhead includes an insulative layer around the lateral edges thereof, particularly those edges not having conductors associated therewith. This insulation creates a more uniform temperature distribution over the heating area, resulting in a uniform nucleation of a vapor bubble within the liquid ink.

摘要： An ejector for a thermal ink-jet printhead includes a heating element defined on a main surface of a silicon heater chip. A cavity is disposed within the heater chip opposite the side of the heating element exposed to liquid ink. In one embodiment, the heating element is disposed on a narrow pillar which is surrounded by two elongated trenches. In another embodiment, the heating element is suspended over a cavity by narrow supports. In each case, the cavity reduces the thermal mass of the structure supporting the heating element and acts as an insulator to prevent excess heat from being dissipated into the body of the heater chip.

摘要： A thermal oxidation process is used to fill trenches with an oxide; however, the oxidation process consumes some of the silicon. The embodiments herein advantageously apply this tendency for the oxidation process to consume silicon so as to convert all the silicon substrate material between the multiple trenches into an oxide. Therefore, because all of the silicon between the multiple trenches is consumed by the oxidation process, the multiple smaller trenches are combined into a single larger trench filled with the oxide.

摘要： The new heater element design has a pit layer which protects the overglaze passivation layer, PSG step region, portions of the Ta layer and dielectric isolation layer and junctions or regions susceptible to the cavitational pressures. Further, the inner walls of the pit layer define the effective heater area and the dopant lines define the actual heater area. In alternative embodiments, the dopant lines define the actual and effective heater areas, and an inner wall and a dopant line define the actual and effective heater areas. Further, when the new heater element designs are incorporated into printheads having full pit channel geometry and open pit channel geometry, the operating lifetime of the printhead is extended because the added protection of the pit layer prevents: 1) passivation damage and cavitational damages of the heater elements; and 2) degradation of heater robustness, hot spot formations and heater failures well into the 109 pulse range. The printhead incorporating the new heater element design can be incorporated into drop-on-demand printing systems of a carriage type or a full width type.
