Abstract
An apparatus comprising: pyroelectric material; an electric field sensor; a first conductive electrode comprising a first area adjacent the pyroelectric material; a second conductive electrode comprising a second area adjacent the electric field sensor; and a conductive interconnection between the first conductive electrode and the second conductive electrode, wherein the first area of the first conductive electrode is larger than the second area of the second conductive electrode.
Claims8
An apparatus comprising:
- a pyroelectric material;
- a patterned conductive material overlying a first area of the pyroelectric material to form a first conductive electrode, and
- an electric field sensor which comprises:
- a channel between a source and a drain,
- a dielectric layer which extends over the channel,
- a gate which is insulated from the channel by the dielectric layer,
- wherein
- the channel contacts the pyroelectric material in a second area of the pyroelectric material, and
- the patterned conductive material overlies the second area of the pyroelectric material to form a second conductive electrode which forms the gate in the electric field sensor,
- wherein the first area is larger than the second area.
