Abstract:
The present invention provides an infrared detector pixel structure and manufacturing method thereof. The structure comprises a conductive metal region on surface of the silicon substrate; an infrared detecting element located above the silicon substrate for detecting infrared light and generating electrical signal; and a conductive beam unit electrically connected to the infrared detecting element for transmitting the electrical signal to the conductive metal region; the conductive beam unit includes at least one conductive beam layer and multilayer conductive trench arranged in a vertical direction; two ends of the conductive beam are respectively in contact with two layers of conductive trenches whose bottom portions are not in the same horizontal plane; the infrared detecting element is in contact with one conductive trench one conductive beam; the conductive metal region is in contact with bottom portion of the other layer of conductive trench therein; the electrical signal is transmitted along the height direction of the conductive trench and the conductive beam, so as to be transmitted downward to the conductive metal region in a circuitous path in the vertical direction.
