Tera-scale Computing and Interconnect Challenges – 3D Stacking Considerations

Tanay Karnik

Principal Engineer
Intel

This presentation will introduce technology scaling trends and new challenges. We are at an I/O inflection point due to Tera-scale computing needs. The tutorial will describe the implication to I/O and memory bandwidth and present various options. 3D integration will be presented in detail with die/wafer stacking considerations. The tutorial outline is as follows:

• Technology scaling trends
  • CMOS transistor scaling
  • Cache memory scaling
  • Projections
• Tera-scale computing
  • Multi-core processor trends
  • High performance computing applications
  • Multi-core processor results
• Implications to interconnects
  • Interconnect bandwidth
  • Memory bandwidth
• Technology options
  • Multi-chip modules
  • System in a package or socket
• 3D stacking considerations
  • Motivation
  • Advantages of 3D
  • Application to memory
  • 3D processing and assembly
  • Thermal consideration

Advanced Packaging Technologies and Future Interconnection Trends

Joseph Fjelstad
Founder
Verdant Electronics

IC packaging technology is the first interconnection element supporting the semiconductor chip, and today is the primary gatekeeper of electronic system performance and a critical technology for all future electronics, There are presently many packaging options available, each with its own benefits and risks, understanding the basics of IC packaging is vital to successful product design. This course reviews common IC packages, including chip scale, BGA, 3-D stacked and folded packages. A review of wafer-level packaging and emerging TSV technologies is also covered.

What you will learn:

• Basic IC packaging roles and functions
• Construction and manufacturing processes for common IC packages
• Impact of IC package design on the assembly processes
• What’s new, and where IC packaging technology is headed
• Role of IC packaging technologies in electronics assembly
• Chip scale packaging types and structures
• Fundamental 3-D packaging concepts, structures and benefits
• Reliability testing and electrical performance of chip scale packages (CSPs)
• Impact of lead-free check points and alternative approaches
• Standards and requirements for substrates
• IC package testing requirements and strategies
• The future of IC packaging and interconnection technology
• Trends in the total integration of IC, package and PCB substrate (e.g., the Occam Process)
• TSV (though silicon via technologies) and their structures
