Abstract :
A measurement system based on crack-opening method has been developed to measure the fracture toughness of silicon direct bonding wafers. The theory of crack-opening method was introduced and amended according to the shape of the specimen. The parameters and function required in the measurement of bond energy were mentioned. A new experimental device based on IR vision and image processing in the measurement was developed. Finally, a contrast experiment was carried out successfully and the error of the method was analyzed which validated the feasibility and the localization of the method
