Claim 16:
17. A method of making a capacitive fingerprint sensor comprising:
forming a plurality of first conductors in a first metal layer of a sensor stack;
forming an insulating layer on top of the first metal layer in the sensor stack; and
forming a plurality of second conductors in a second metal layer of the sensor stack, the second metal layer being formed on top of the insulating layer;
wherein at least a portion of the plurality of first conductors form a plurality of transmitter electrodes or a plurality of receiver electrodes of the capacitive fingerprint sensor, the portion of the plurality of first conductors including both (i) a plurality of first conductors disposed between pixels of a display and (ii) a plurality of first conductors intersecting pixels of the display, and
wherein at least a portion of the plurality of second conductors form the other of the plurality of transmitter electrodes or the plurality of receiver electrodes not formed by the first conductors, the portion of the plurality of second conductors including both (i) a plurality of second conductors disposed between pixels of the display and (ii) a plurality of second conductors intersecting pixels of the display.
