Abstract

The invention provides a chip testing system which comprises a first platform, a feeding mechanism, a simulation laser mechanism, a first testing mechanism, a second testing mechanism, a third testing mechanism and a controller, and the feeding mechanism, the simulation laser mechanism, the first testing mechanism, the second testing mechanism and the third testing mechanism are connected with the controller. The integrating sphere of the first testing mechanism is used for obtaining a first testing signal, the second testing mechanism is matched with the integrating sphere, a fifth light intensity signal is obtained through the integrating sphere, and the third testing mechanism is used for obtaining third light intensity information and a fourth light intensity signal; the controller is used for calculating to obtain bare test power, test power and a divergence angle according to the first light intensity signal, the fifth light intensity signal, the third light intensity signal and the fourth light intensity signal, calculating the polarization degree of the chip to be tested according to the bare test power and the test power, and judging whether the chip to be tested is qualified or not according to the bare test power, the polarization degree and the divergence angle; and outputting a test result. And the test efficiency and accuracy are improved.

Description

technical field [0001] The application belongs to the technical field of semiconductor testing, and in particular relates to a chip testing system. Background technique [0002] With the rapid development of the semiconductor laser industry, the laser chip is tested. However, in the existing test equipment, the function of the test equipment is single, and it is necessary to test different performances on different test equipment. During the test, it needs to be replaced frequently. The test equipment has low test efficiency, and the data tested by all test equipment is stored separately, so the integrity of the data cannot be tested. Contents of the invention [0003] The embodiment of the present application provides a chip testing system to solve the problems of single function and incomplete test data of existing chip testing equipment. [0004] In the first aspect, the embodiment of the present application provides a chip testing system, including: [0005] the firs...
