Semiconductor packaging technology requires understanding how the fundamental materials properties of different structures interact to impact the final reliability of the system, how to measure those properties and how to control them. We investigate

We present a review of the application of diffraction stress/strain analysis to small volumes. For cases in which the material properties and/or the stress state are not homogeneous, traditional approaches may yield erroneous stress results. On the o

During the solidification of solder joints composed of near-eutectic Sn–Ag–Cu alloys, the Sn phase grows rapidly with a dendritic growth morphology, characterized by copious branching. Notwithstanding the complicated Sn growth topology, the Sn ph

The electronic industry is making substantial progress toward a full transition to Pb-free soldering in the near future. At present, the leading candidate Pb-free solders are near-ternary eutectic Sn-Ag-Cu alloys. The electronic industry has begun to

Flip-chip carriers have become the preferred solution for high-performance, application-specific integrated circuit and microprocessor devices. Typically, these are packaged in organic or ceramic ball grid array (BGA) packages, which cover a wide ran

Near-ternary eutectic Sn–Ag–Cu alloys are leading candidates for Pb-free solders. These alloys have three solid phases: β–Sn, Ag3Sn, and Cu6Sn5. Starting from the fully liquid state in solidifying near-eutectic Sn–Ag–Cu alloys, the equilib

Recently, the research and development activities for replacing Pb-containing solders with Pb-free solders have been intensified due to both competitive market pressures and environmental issues. As a result of these activities, a few promising candi

Conventional formulations of thermal stress evolution in interconnect structures usually ignore the interface integrity between the various levels. In this letter we present thermal and residual stress versus temperature data from simple copper thin-

A study of NiFe alloy as under bump metallurgy (UBM) for Pb-free interconnect has been performed. Intermetallic growth rate of NiFe and SnAg solder is about 10x slower than that of Ni and SnAg solder. The thin and uniform intermetallic compound FeSn2
