description Methods for fabricating micro-fluid ejection heads and micro-fluid ejection heads are provided herein, such as those that use non-conventional substrates. One such micro-fluid ejection head includes a substrate having first and second glass layers disposed adjacent to a surface thereof and a plurality of fluid ejection actuators disposed adjacent to the second glass layer. The first glass layer is thicker than the second glass layer and the second glass layer has a surface roughness of no greater than about 75 Å Ra.
