AI Article Synopsis
- The study investigates how varying concentrations of bis-(3-sulfopropyl) disulfide (SPS) in electroplated copper (Cu) foils impact their mechanical properties, particularly during tensile tests.
- It finds that the SPS concentration influences the grain size of the Cu foils, which is crucial for their reliability in electronic packaging applications.
- The research highlights a significant Hall-Petch effect, where changes in grain size due to SPS impurities lead to different fracture behaviors in the material.
Article Abstract
Electroplated Cu has been extensively applied in advanced electronic packaging, and its mechanical properties are critical for reliability. In this study, Cu foils fabricated through electroplating with various bis-(3-sulfopropyl) disulfide (SPS) concentrations are examined using tensile tests. The SPS concentration affects the grain size of the electroplated Cu foils, resulting in different mechanical properties. A significant Hall-Petch effect, [Formula: see text], is demonstrated for the electroplated Cu foils. The different concentrations of impurities identified through time-of-flight secondary ion mass spectrometry correspond to the different grain sizes, determining the transgranular and intergranular fracture during the tensile test. The results demonstrate that the SPS concentration controlling the microstructures of the electroplated Cu results in a Hall-Petch effect on the mechanical properties of the electroplated Cu foils.
