Abstract
Fhis paper discusses the extensive development work carried out by GLOBALFOUNDRIES to mitigate chip-package interaction (CPI) risks for the silicon Backend of Line (BEOL) during IC package assembly. Particularly, material property data for different ultra low k (ULK) materials, CPI qualification results and key findings made during the technology development are discussed. Newly developed test and modeling methods to expedite technology learning are also described in detail.
