Abstract: A fluid ejection device comprises a first heater element and a second heater element spaced a first distance from the first heater element. A first drive transistor is associated with the first heater element and a second drive transistor is associated with the second firing heater element. The second drive transistor is spaced a second distance from the first drive transistor. The second distance is different from the first distance.

Abstract: The described embodiments relate to slotted substrates. One exemplary method forms a feature into a substrate, at least in part, by directing a laser beam at the substrate. During at least a portion of said directing, the method supplies a conductive material proximate the substrate.

Abstract: Processing a die that has an edge and a substrate upon which a layer of moisture permeable material is disposed. The moisture permeable material extends to the edge of the die. One embodiment comprises interrupting the layer of moisture permeable material to form a gap at a boundary near the edge, thereby to substantially block movement of moisture through the gap of the moisture permeable material.
