Claim:
1. An integrated infrared sensor device, comprising: a sensor substrate having a back surface and a front surface opposite the back surface, said back surface having a cavity defined therein, said front surface having at least one infrared sensing element formed therein or arranged thereon, and a filter substrate arranged on said back surface of the sensor substrate such that said filter substrate at least partially covers the cavity, the filter substrate furthermore being adapted in shape and composition to transmit infrared radiation and to attenuate radiation in at least part of the visible light spectrum, and a cap for protecting the at least one sensing element, said cap being arranged on the front surface, the integrated infrared sensor device further comprising at least one solder bump arranged on the front surface of the sensor substrate for connecting the integrated infrared sensor device to a carrier in a flip-chip arrangement.
