Abstract (en)
[origin: WO2007041744A1] An inkjet printhead with planar thermal actuators (12), contacts (28) directly deposited onto the CMOS electrodes and suspended heater element (29), which avoids hot spots caused by vertical or inclined surfaces so that the contacts (28) can be much smaller structures without unacceptable increases in resistive losses. Low resistive losses preserves the efficient operation of a suspended heater element (29) and the small contact size is convenient for close nozzle packing on the printhead.
