DNA Edges Forward As Data Storage Option
By Bernadette Tansey - 28 Sep, 2022 - Comments: 0

At technology conferences back in 2015, scientist David Markowitz raised the idea that DNA could be adapted as a data storage material. The audience response wasn’t all he had hoped for. “They would laugh me off the podium,” Markowitz recalls, but without rancor. Facing skepticism comes with his job at IARPA, the research arm of the U.S. intelligence community. The agency anticipates f... » read more

Strengthening The Global Semi Supply Chain
By Ann Steffora Mutschler - 22 Sep, 2022 - Comments: 0

This confluence of all these factors is creating disruptions around the globe. Compounding that, the end customer base is shifting from traditional chipmakers designing for a socket to a combination of systems companies, existing chipmakers, and a slew of new players that are developing chips for very specific applications. Some of those are being developed at the most advanced nodes, particula... » read more

Can ML Help Verification? Maybe
By Brian Bailey - 22 Sep, 2022 - Comments: 0

Functional verification produces an enormous amount of data that could be used to train a machine learning system, but it's not always clear which data is useful or whether it can help. The challenge with ML is understanding when and where to use it, and how to integrate it with other tools and approaches. With a big enough hammer, it is tempting to call everything a nail, and just throwing ... » read more

Progress In Quantum Computing
By Marie C. Baca - 22 Sep, 2022 - Comments: 0

A recent wave of quantum computing investment has given rise to claims of a quantum computing bubble, based on overly optimistic technological claims in a field area that experts say has yet to demonstrate any real utility. But executives on the industry’s front lines say quantum computing is indeed a commercially viable technology, albeit one that is at least several years away from overcomi... » read more

How Memory Design Optimizes System Performance
By John Koon - 21 Sep, 2022 - Comments: 0

Exponential increases in data and demand for improved performance to process that data has spawned a variety of new approaches to processor design and packaging, but it also is driving big changes on the memory side. While the underlying technology still looks very familiar, the real shift is in the way those memories are connected to processing elements and various components within a syste... » read more

10 Questions: Handel Jones
By Ed Sperling - 20 Sep, 2022 - Comments: 0

Handel Jones, CEO of International Business Strategies and author of a new book, "When AI Rules The World," sat down with Semiconductor Engineering to talk about the growth and impact of AI. What follows are excerpts of that conversation. SE: What do you see as the impact of AI on semiconductors? Jones: The fact that you have a 5G smart phone is because of AI. Steve Jobs changed the smart... » read more

Why Geofencing Will Enable L5
By Marie C. Baca - 19 Sep, 2022 - Comments: 1

What will it take for a car to be able to drive itself anywhere a human can? Ask autonomous vehicle experts this question and the answer invariably includes a discussion of geofencing. In the broadest sense, geofencing is simply a virtual boundary around a physical area. In the world of self-driving cars, it describes a crucial subset of the operational design domain — the geographic regio... » read more

Improving Redistribution Layers for Fan-out Packages And SiPs
By Laura Peters - 15 Sep, 2022 - Comments: 0

Redistribution layers (RDLs) are used throughout advanced packaging schemes today including fan-out packages, fan-out chip on substrate approaches, fan-out package-on-package, silicon photonics, and 2.5D/3D integrated approaches. The industry is embracing a variety of fan-out packages especially because they deliver design flexibility, very small footprint, and cost-effective electrical connect... » read more

How To Compare Chips
By Ed Sperling - 15 Sep, 2022 - Comments: 0

Traditional metrics for semiconductors are becoming much less meaningful in the most advanced designs. The number of transistors packed into a square centimeter only matters if they can be utilized, and performance per watt is irrelevant if sufficient power cannot be delivered to all of the transistors. The consensus across the chip industry is that the cost per transistor is rising at each ... » read more

The High Price Of Smaller Features
By Katherine Derbyshire - 15 Sep, 2022 - Comments: 0

The semiconductor industry’s push for higher numerical apertures is driven by the relationship between NA and critical dimension. As the NA goes up, the CD goes down: Where λ is the wavelength and k1 is a process coefficient. While 0.55 NA exposure systems will improve resolution, Larry Melvin, principal engineer at Synopsys, noted that smaller features always come with a process cos... » read more
