Abstract
An infrared light sensor chip comprises a substrate (2), an infrared light sensor (9), which has a base electrode (10) that is in direct contact with one side (8) of the substrate (2) and which is used to attach the infrared light sensor (9) to the substrate (2), and a resistance thermometer (13), which has a resistance path (14) in direct contact with the side (8) of the substrate (2) adjacent to the infrared light sensor (9) and configured to measure the temperature of the substrate (2) via the resistance thermometer (13). The resistance path (14) is made of the same material of which the base electrode (10) is made.
