Semiconductor temperature sensor using spreading-resistance principle, has 2 relatively spaced electrodes provided at surface of semiconductor layer

摘要

The temperature sensor has a semiconductor layer (4) provided with at its surface with an electrode (6a) matched in size to the temperature sensor resistance value and a second electrode (10a) of greater size, the smallest distance (d) between the electrodes being greater than the size of the first electrode. The first electrode can be provided as a circle coaxially enclosed by the second electrode in the form of a ring.
