A tool box for successful 3D Integration

Mark Scannell Mark Scannell
Program Director, 3D Integration
CEA - Léti

This tutorial presents a technology focused over-view on 3D developments from the perspective of French public research. The notion of a generic technology toolbox, from which to pick and choose integration schemas will be presented. Different approaches to 3D technology integration will also be presented; notably 3D (and 2.5D) interposer technologies, 3D-IC technologies and heterogeneous integration (TSV-less) technologies.

• Development of 3D tool box

• Interposer approach

• 3D-IC approach

• Heterogeneous approach

Modern 3D packaging technologies driving the need for IC, Package & PCB Co-Design methodologies

John Park John Park
Methodology Architect
Mentor Graphics

IC packaging has evolved from a simple, primarily mechanically oriented design task, to a very challenging, primarily electrically oriented design task. Flip-chips and routable package substrates introduced a new set of design challenges. C4 bumps, RDL routing and package level interconnect (including vias) added a tremendous amount of additional complexity to the off-chip interconnect path. Looking beyond the physical design challenges, I/O are getting faster and faster, meaning designers now had to pay more attention to off-chip signal integrity and power delivery. Package optimization, design and modeling became much more difficult. Modern 3D packaging technologies are now broadening package design challenges by introducing a new set of off-chip interfaces, including TSV interconnect, micro-bumps and silicon interposers. Managing this extremely complex off-chip interconnect path is one thing. Optimizing this interconnect path for routability, signal integrity and power delivery is where the real challenge lies. This tutorial will discuss the challenges involved with defining and developing a complete chip, package, board co-design methodology to support modern 3D packaging technologies.

Memory Packaging Challenges and Approaches for the Evolving World of the Portable Client and Cloud Computing

Ilyas Mohammed Ilyas Mohammed
Senior Director and Principal Technologist
Tessera

Traditionally, memory performance has increased at a slower pace than that of CPUs, GPUs and ASICs. Besides increasing frequency, doubling and quadrupling of data transfer per clock signal (DDR and QDR) have increased data throughput, which have put tighter design constraints on both memory packaging and system design. To further increase the bandwidth while maintaining current system design, multiple channels per CPU have been implemented. Though these have addressed performance issues related to desktop systems, rapid change in system form-factors away from desktops, such as mobile (phones, tablets) and cloud computing (search, social, media) have added new challenges but also have provided new opportunities. The new challenges include miniaturization including multi-chip packaging, low power solutions for both mobile and data-center applications, and high capacity while delivering high performance. In this presentation, details regarding package level reliability and performance will be presented. The limitations of current system designs will be shown. Two example applications, mobile and data-centers, will be addressed and memory packaging approaches will be discussed. The challenges of wide IO for mobile memory will be covered in terms of packaging configurations and their trade-offs. For the data-center applications, multi-chip packaging and their implementation in conventional systems and possible new configurations will be presented.

3D Silicon Interposer and Through Silicon Via (TSV): Application, Requirement, Infrastructure and Technologies

Farhang Yazdani Farhang Yazdani
President and CTO
BroadPak Corporation

As the semiconductor industry migrates toward extreme monolithic foundry level 3D heterogeneous structures for mixed-signal components and systems, 3D silicon/glass interposer and through silicon via (TSV) technology will play a significant role in next generation 3D packaging solutions. It is ubiquitous that 3D integration technologies are well suited to realize high density and high performance heterogeneous systems. 3D integration technologies rely on TSV technology, wafer thinning/handling technology and micro-bump technology. This presentation provides the fundamentals and individual skill sets mandatory for 3D integration technologies. In particular, wafer thinning and bonding , silicon/glass interposer design rules and supply chain, application specific silicon/glass interposer selection guideline, TSV manufacturing and thermal stress effect, signal-power integrity, test and verification, cost analysis for 3D processes and EDA tool perspective will be presented.
