Patent ID: 7635179

Claim:
A print head comprising: a substrate; a plurality of row conductors arranged on the substrate; a plurality of column conductors arranged on the substrate; a plurality of ejectors arranged on the substrate in rows and columns, each of the plurality of ejectors including a resistive element arranged over the substrate and a supply passage through the substrate dedicated to each of the plurality of ejectors; and a semiconductor device associated with each resistive element, the semiconductor device being responsive to a signal from one of the plurality of row conductors or one of the plurality of column conductors to actuate the resistive element associated with the semiconductor device, the semiconductor device including first and second electrical contacts and a gate, wherein each resistive element is electrically connected to either one of the plurality of row conductors or one of the plurality of column conductors and the first electrical contact of the semiconductor device, the gate of the semiconductor device is electrically connected to the other of either the one of the plurality of row conductors or one of the plurality of column conductors, and the second electrical contact of the semiconductor device is electrical connected to the substrate.
