摘要
利用接触弹性力学的DMT(Derjaguin,Muller,Toporov)理论,考虑晶片表面起伏的随机性,导出了晶片键合的实际接触面积和有效键合能。并对结果进行了数值分析。讨论了影响室温键合强度大小的各种因素。
Based on the DMT theory on the contact and adhesion between elastic bodies, considering the random distribution of wafer surface asperity topography, the real area of contact between two wafers and effective wafer bonding energy in room temperature were calculated. The relevant parameters that influenced on wafer bonding strength were discussed through the numerical simulations.
