ABSTRACT:
A fluid ejection device with a firing chamber from which fluid is ejected, a heating element that heats fluid in the firing chamber and, drive circuitry for the heating element having a field effect transistor (FET). At least part of the firing chamber overlaps the FET when viewed in a direction parallel to the direction of fluid ejection, and the firing chamber and the FET is separated by a layer of insulating material.
