Test and Reliability of 2.5D / 3D ICs

Despite the numerous benefits offered by 3D integration, testing remains a major obstacle that hinders its widespread adoption. Concerns related to test cost, yield and reliability continue to derail the commercial exploitation of 2.5D and 3D ICs. The increased density and performance they provide can also lead to high current densities and increased local heat, which in turn can lead to interconnect degradation and manifestation of latent defects.

In this talk, the first speaker will examine the hype, myths, and realities of 2.5D and 3D ICs; he will present a number of testing and DfT challenges, and provide an overview of some of the most recent solutions being advocated for these challenges. The presentation will cover in more detail DfT techniques for pre-bond testing and diagnosis of TSVs, and a BIST control technique for stacked ICs.

The second speaker will also present new techniques for testing and monitoring the performance of high density vertical interconnects that are beyond the reach of conventional test hardware. New methods are needed to bring these interconnect technologies into common usage in high-value systems.

During the webinar you will learn about the solutions Ridgetop Group offers for monitoring and qualifying interconnect reliability in 2.5D and 3D assembly and packaging technologies. These solutions can detect intermittencies beyond permanent failures, and can be used during qualification as well as for lifetime monitoring.

Learning Objectives

Learn about the current state of the art in advanced stacked die packaging techniques.
Understand key tradeoffs to consider when choosing an advanced packaging strategy.
See innovative solutions that can detect problems in internal interconnections, including intermittencies, and warn of impending failure before it occurs.
