description A thermal ink jet printhead including a thin film substrate with a plurality of polygon shaped thin film resistors, a barrier layer overlying the substrate, and respective firing chambers formed in the barrier layer for each of the resistors. Each firing chamber is formed of a continuously curved concave wall having ends adjacent the boundary of the resistor, and which is within the boundary of the area defined by the resistor and a 10 micrometer wide margin around the resistor.
