Abstract

The invention relates to an electric breakdown life testing method, device and system of a TSV structure and control equipment. The method comprises the following steps of acquiring an initial leakagecurrent of a to-be-tested TSV matrix wafer sample under an initial voltage through signal acquisition equipment in a first temperature cycle period, wherein the first temperature cycle period is a first period of controlling temperature adjusting equipment to adjust the test environment temperature of the to-be-tested TSV matrix wafer sample to be changed cyclically; when the initial leakage current is lower than or equal to a preset value, controlling power supply equipment to gradually increase a voltage applied to the to-be-tested TSV matrix wafer sample by taking the initial voltage as astarting point, and acquiring a current leakage current of the to-be-tested TSV matrix wafer sample in real time through the signal acquisition equipment; and when the current leakage current meets failure criteria, obtaining a total voltage adjusting duration of the power supply equipment, and confirming the total duration as the failure time of the to-be-tested TSV matrix wafer sample. The service life performance of the TSV structure is efficiently and accurately tested, and the electric breakdown reliability of the TSV structure is efficiently and accurately tested.

Description

technical field [0001] The present application relates to the technical field of wafer performance testing, in particular to a TSV structure electrical breakdown life testing method, device, system and control equipment. Background technique [0002] The new three-dimensional integration method based on TSV (Through silicon via) technology has higher integration density and higher performance, and is the cutting-edge application direction of advanced packaging at home and abroad. TSV three-dimensional integration technology is supported by through-silicon via interconnection and chip stacking technology, and realizes vertical integration and data transmission between homogeneous or heterogeneous chips through TSV vertical interconnection. TSV vertical interconnection breaks through the technical bottleneck of planar integration in terms of data transmission and functional density, greatly improves device information processing speed, and greatly reduces system volume, weight...
