ABSTRACT:
A temperature sensor and fabrication technique for making the sensor. An insulating substrate supporting a conductive resistive pattern is laser trimmed until the pattern has a desired resistance. Back and forth movement of the laser is controlled at an automated laser trimming station. The laser trimmer compares the sensed resistance of the conductive resistance pattern with a sensor pattern that has already been precisely trimmed to a desired resistance and is used as a standard.
