发明名称 Semiconductor device including a hybrid metallization layer stack for enhanced mechanical strength during and after packaging
摘要 The introduction of dielectric material of enhanced mechanical stability, such as silicon dioxide or fluorine-doped silicon dioxide, into the via level of a low-k interconnect structure provides an increased overall mechanical stability, especially during the packaging of the device. Consequently, cracking and delamination, as frequently observed in high end low-k interconnect structures, may significantly be reduced, even if organic package substrates are used.
