Processor Tradeoffs For AI Workloads
By Ann Mutschler - 10 Aug, 2023 - Comments: 0

AI is forcing fundamental shifts in chips used in data centers and in the tools used to design them, but it also is creating gaps between the speed at which that technology advances and the demands from customers. These shifts started gradually, but they have accelerated and multiplied over the past year with the rollout of ChatGPT and other large language models. There is suddenly much more... » read more

Chiplets: Deep Dive Into Designing, Manufacturing, And Testing
By The SE Staff - 07 Aug, 2023 - Comments: 0

Chiplets are a disruptive technology. They change the way chips are designed, manufactured, tested, packaged, as well as the underlying business relationships and fundamentals. But they also open the door to vast new opportunities for existing chipmakers and startups to create highly customized components and systems for specific use cases and market segments. This LEGO-like approach sounds ... » read more

Smarter Systems Through Heterogeneous Integration: Highlights From 3D & Systems Summit
By Cassandra Melvin - 25 Jul, 2023 - Comments: 0

It has taken decades of research and development and strong commitment to various industry programs, but the stars are finally aligning for 3D semiconductor systems. No one could have left the 3D & Systems Summit 2023 – held in late June in Dresden – with any doubt that heterogeneous integration, enabled by increasingly mature 3D packaging technologies, is becoming a key driver of the s... » read more

Better Choreography Required For Complex Chips
By Karen Heyman - 22 Jun, 2023 - Comments: 0

The rapidly growing number of features and options in chip design are forcing engineering teams to ratchet up their planning around who does what, when it gets done, and how various components will interact. In effect, more elements in the design flow need to be choreographed much more precisely. Some steps have to shift further left, while others need to be considered earlier in the plannin... » read more

3DICs: Legalizer Techniques For Better Routing Quality, Fewer DRVs, And Reduced Total Slack With Negligible Runtime Impact
By Technical Paper Link - 07 Jun, 2023 - Comments: 0

A technical paper titled “On Legalization of Die Bonding Bumps and Pads for 3D ICs” was published by researchers at the Georgia Institute of Technology, NVIDIA Corporation, and the University of Bremen. Abstract "State-of-the-art 3D IC Place-and-Route flows were designed with older technology nodes and aggressive bonding pitch assumptions. As a result, these flows fail to honor the widt... » read more

Photonic Debond: Scalability And Advancements
By Brewer Science - 17 May, 2023 - Comments: 0

Advanced packaging technology has continuously evolved over the past 10-20 years to become a major driving force in improving integrated circuit (IC) performance. This improvement in IC performance is assisted by the ability to place specialized components near each other for shorter interconnects in the IC packages. Temporary bond and debond (TB/DB) is an enabling technique for this work. TB/D... » read more

Circuit Design For Industry 4.0
By Bjorn Zeugmann - 11 May, 2023 - Comments: 0

By Björn Zeugmann and Olaf Enge-Rosenblatt The digitalization of industry is progressing in leaps and bounds, albeit not at the same speed everywhere. In many industries, processes can be digitalized well to very well — for example, because electronic control systems can be retrofitted from analog to digital relatively easily. In some cases, new industries emerge only because processes ha... » read more

3D-IC Design: An Innovative Approach To Chip Integration
By Akanksha Soni - 11 May, 2023 - Comments: 0

Advancements in technology have led to the development of increasingly complex and densely integrated circuits (ICs). To keep up with the ever-growing demand for high-performance and power-efficient devices, the industry has shifted toward 3D-IC design. 3D-ICs have many applications in a wide range of industries, including consumer electronics, telecommunications, computing, and automotive. Wh... » read more

True 3D-IC Problems
By Brian Bailey - 27 Apr, 2023 - Comments: 0

Placing logic on logic may sound like a small step, but several problems must be overcome to make it a reality. True 3D involves wafers stacked on top of each other in a highly integrated manner. This is very different from 2.5D integration, where logic is placed side-by-side, connected by an interposer. And there are some intermediate solutions today where significant memory is stacked on l... » read more

Thermal Integrity Challenges Grow In 2.5D
By Ann Mutschler - 13 Apr, 2023 - Comments: 3

Thermal integrity is becoming much harder to predict accurately in 2.5D and 3D-IC, creating a cascade of issues that can affect everything from how a system behaves to reliability in the field. Over the past decade, silicon interposer technology has evolved from a simple interconnect into a critical enabler for heterogeneous integration. Interposers today may contain tens of dies or chiplets... » read more
