    • A semiconductor substrate for a micro-fluid ejection device. The substrate includes plurality of micro-fluid ejection actuators disposed adjacent a fluid supply slot in the semiconductor substrate. A plurality of power transistors, occupying a power transistor active area of the substrate, are disposed adjacent the ejection actuators and are connected through a first metal conductor layer to the ejection actuators. An array of logic circuits, occupying a logic circuit area of the substrate, is disposed adjacent the plurality of power transistors and is connected through a polysilicon conductor layer to the power transistors. A power conductor and a ground conductor for the ejection actuators is routed in a second metal conductor layer. The power conductor overlaps at least a portion of the power transistor active area of the substrate and the ground conductor overlaps at least a portion of the logic circuit area of the substrate.

    • A magnetic field sensor device (2) is described that comprises an oscillatory member (8) and current control means (6). The current control means (6) is arranged to pass an alternating current (AC) along at least first (10) and second (12) current paths provided through the oscillatory member (8) and is arranged to provide magnetic gradiometer mode operation (i.e. to measure magnetic field gradient) in which current flow through the first current path (10) is in substantially the opposite direction to current flow through the second current path (12). The current control means (6) can also prove magnetometer mode operation (i.e. to measure magnetic field strength). The magnetic field sensor (2) may be used in a compass.
