Thermal ink-jet printhead method for generating homogeneous nucleation
 A thermal ink-jet type printhead is disclosed which comprises a strip-like thin metallic layer formed on a substrate. The layer is configured so as to define a narrow portion which is positioned between broad portions. The narrow portion defines a heating element which is integral with the broad portions which act as electrodes. Electrical heating pulses are supplied to the narrow heater portion via the electrodes. The heater arrangement is durable to thermal stresses generated by a superheating and, accordingly is well suited for spontaneous or homogeneous nucleation.
