Embodiment 1

[0031] Such as figure 1 As shown, a test system that supports log file configuration disclosed in the embodiment of the present invention includes: a workstation 1, a test machine 2 and a probe station 3; the workstation 1, the test machine 2 and the probe station 3 are sequentially connected by communication , and perform signal transmission; the probe station 3 is provided with a probe card 31 and a wafer box 32, the wafer box to be tested 321 is placed in the wafer box, and the probe card 31 is connected to the wafer to be tested 321; the workstation 1 It includes a memory 11 and a processor 12; the memory 11 stores a test program, and the test program supports log file configuration; the test program is run by the processor to generate multiple log files according to the configuration. The log files in this embodiment include log files related to the test process and log files related to the test status. In this embodiment, the signal transmission process in the test work...

Embodiment 2

[0061] Such as figure 2As shown, the main difference between the second embodiment and the first embodiment is that a test system that supports log file configuration disclosed in this embodiment also includes a server 4, which is connected by communication with the workstation 1; in this embodiment, the log file is stored in the server 4 on. Of course, in some embodiments, the log files are stored on both the workstation 1 and the server 4, which is not limited. In addition, different from Embodiment 1, the log file in this embodiment also includes log files related to inspection results, specifically, the output of the Self testlog is the hardware and communication inspection results of the current machine. The inspection items involved in the results displayed by Self test log in this embodiment include 13 items, specifically GPIB: whether the GPIB communication module can communicate normally; ControlBus: whether the control bus is working normally; SMU: Source Measureme...

Abstract

The invention provides a test system supporting log file configuration. The test system comprises a workstation, a test machine and a probe station, the work station, the test machine and the probe station are in communication connection in sequence and perform signal transmission. The workstation comprises a memory and a processor; the memory stores a test program, and the test program supports log file configuration; the log files comprise the log file related to the test process, the log file related to the test state and the log file related to the check result, information such as the test process, the test state and the abnormal problem can be displayed, records are not prone to loss, the record content is complete, and the test information recording effect and the problem solving efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of semiconductor testing, and in particular relates to a testing system supporting log file configuration. Background technique [0002] The manufacturing process of integrated circuits is very complicated and the cost is very high. Therefore, as an important means of discovery research and discovery of yield, integrated circuit testing occupies an indispensable position. The current advanced integrated circuit design and manufacturing capabilities provide a huge support for the realization of more powerful chips with more functions and performance. challenge. The market needs low-cost, high-performance and fast-to-market products. If test program designers cannot quickly and effectively complete the test program, it will become a bottleneck in mass production and shipment, delaying the time to market and causing great economic losses. . These all show that in the whole process from R&D to production and ...
