Wafer Bumping Considerations: The importance of the interface between metal layers

March 15, 2016

Capped pillar – intermetallic compound compatibility, metal layer interface

Many new assembly processes are in development, including ultra thinning of wafers to enable stacked die, package-on-package (PoP) and ultra-thin packages. Wafer-level packaging (WLP) to improve reliability and I/O count, ball pitch and routability are also imperative. This post provides an introduction on materials considerations for the interface between metal layers in wafer bump structures.
