摘要： A method produces a matrix of pixels of a thermal sensor, suitable for passive addressing. The matrix of pixels includes a layer including a first series of electrically conducting strips, forming charge collection macro-electrodes; a layer including a pyroelectric material; and a layer including a second series of electrically conducting strips, forming heating strips. The method includes a step of transfer of one on the other of a first and a second elementary stack, the first elementary stack including the first series of strips, and the second elementary stack including the second series of strips. This method makes it possible to relax the manufacturing constraints of the series of strips.

摘要： The invention relates to a heat pattern sensor comprising a matrix of pyroelectric capacitances. The heat pattern sensor further comprises an electromagnetic shielding stage, electrically conducting, situated between a stage including a pyroelectric material and a protective layer of the matrix of pixels. The electromagnetic shielding stage includes an insulating layer, and a plurality of pads distributed in the insulating layer, the pads having a thermal conductivity greater than that of the insulating layer. The invention makes it possible to obtain at one and the same time rapid heat transfers through the electromagnetic shielding stage, and low lateral heat transfers, from one pixel to the other of the sensor.
