【Abstract】 In conjunction with ANSYS,we use the finite element method to analyze the bonding stresses of Si/GaAs.We also apply a numerical model to investigate a contour map and the distribution of normal stress,shearing stress,and peeling stress,taking into full consideration the thermal expansion coefficient as a function of temperature.Novel bonding structures are proposed for reducing the effect of thermal stress as compared with conventional structures.Calculations show the validity of this new structure.更多还原
