Device and method for testing performance of thermoelectric power generation chip

Abstract

The invention relates to the field of semiconductor device performance testing, in particular to a device and method for testing the performance of a thermoelectric power generation chip. The device comprises an atmosphere environment control module, a temperature environment control module, an electric signal control and test module and automatic test software. The atmosphere environment control module creates testing environments of different atmosphere environments for a sample to be tested, and the testing environments specifically comprise a vacuum environment, an inert gas environment, an air environment and a low-pressure environment; the temperature environment control module provides a temperature difference environment required by thermoelectric power generation for the to-be-tested sample; the electric signal control and test module provides an external load circuit for the to-be-tested sample and detects voltage and current signals of the circuit. The automatic test software is respectively connected with the atmosphere environment control module, the temperature environment control module and the electric signal control and test module, can provide different test atmospheres, temperature differences and load circuit environments for the to-be-tested sample through centralized control, and detects and obtains data. According to the invention, multiple parameters of the performance of the thermoelectric power generation chip can be tested and calculated, the power generation performance detection of the chip in different temperature difference environments is realized by replacing a heater and a radiator assembly of the temperature environment control module, the scene of a product in practical application is simulated, and the test efficiency is improved. And the research on the thermoelectric power generation chip is promoted.

Description

technical field [0001] The invention relates to the field of semiconductor devices, in particular to a device and method for testing the performance of a thermoelectric power generation chip. Background technique [0002] Among many new energy technologies, thermoelectric conversion technology has attracted much attention because it can directly use various waste heat in daily life to generate electricity to realize the secondary utilization of energy, and has no secondary pollution to the environment. The low utilization rate of industrial waste heat is an important reason for high energy consumption. The waste heat and energy of major industries in my country account for ~20% of the total industrial energy consumption. The utilization of high-temperature waste heat is relatively good at home and abroad, but there is no good utilization technology for medium-low temperature (below 300 °C) waste heat; centralized waste heat utilization is better, but there is no good utiliza...
