Title:
PYROELECTRIC INFRARED IMAGING ELEMENT AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2002334977
Kind Code:
A
Abstract:
To reduce the pixel size of a pyroelectric infrared imaging element.
A plurality of polarization reversal sections 12, showing separated patterns on one surface 11b thereof, is formed on the pyroelectric material 11 consisting of an LiTaO3 crystal substrate, etc., which is singly polarized, thereby forming a light-receiving section 10 for receiving infrared rays 2 by the surface 11a opposite to the surface 11b. A charge transfer section 20 is disposed on the surface 11b side of the section 10, and the section 20 is conducted, to each of the section 12 by a junction means 30, and thus a pyroelectric infrared imaging element 1 is constituted.
