Abstract:
1. An inkjet printhead comprising: a supporting substrate; a conductive layer deposited in a pattern on one side of the supporting substrate; an insulating layer deposited such that the conductive layer is between the insulating layer and the supporting substrate; an ink chamber supported on the supporting substrate; a nozzle in fluid communication with the ink chamber; a heater positioned in the ink chamber to vaporize some ink in the ink chamber such that a droplet of ink is ejected through the nozzle, the heater having a resistive element extending between a pair of contacts; and, one or more metallic vias extending through the insulating layer, each metallic via connecting a respective contact with the conductive layer; wherein, the insulating layer and one end of each of the metallic vias have coplanar surfaces on which the heater is supported.
