Description

technical field [0001] The invention relates to the field of semiconductor thermoelectric effect testing, in particular to a novel automatic system and method for measuring the thermoelectric effect of semiconductor components integrated with multiple signal generation modules and multiple thermoelectric effect detection modules. Background technique [0002] For electronic components, the operating temperature has a great influence on the performance of components. Electronic components have a certain power, and the internal or external temperature of the components will change with the accumulation of heat in the working state, and the temperature change will in turn affect the working state of the components, that is, the thermoelectric coupling phenomenon. The most direct example is that for bipolar transistors, the accumulation of heat makes the internal temperature of the bipolar transistor rise, and the current increases with the increase of the internal temperature, ...
