Abstract:
1. A temperature sensor, comprising: a substrate; a sensor structure arranged on a first surface of the substrate, wherein the sensor structure includes a length of a meander-shaped resistive film having a first end and a second end; an insulation layer at least partially arranged on the sensor structure and the first surface of the substrate; a first and a second contact area arranged on the insulation layer; a third and a fourth contact area arranged on the first surface of the substrate and in conductive connection with the first and the second end of the resistive film, respectively, and in conductive connection with the first and the second contact area on the insulation layer, respectively, wherein the first and the second contact areas have a surface dimension at least 2 times greater than a corresponding surface dimension of the third and fourth contact areas; and wherein the length of resistive film of the sensor structure substantially completely covers the first surface of the substrate.
