Is UCIe Really Universal?
By Brian Bailey - 22 Nov, 2022 - Comments: 3

Chiplets are rapidly becoming the means to overcome the slowing of Moore's Law, but whether one interface is capable of joining them all together isn't clear yet. The Universal Chiplet Interconnect Express (UCIe) believes it will work, but some in the industry remain unconvinced. At least part of the problem is that interconnect standards are never truly finished. Even today, the protocols tha... » read more

On-Chip Power Distribution Modeling Becomes Essential Below 7nm
By Ann Mutschler - 16 Nov, 2022 - Comments: 0

Modeling power distribution in SoCs is becoming increasingly important at each new node and in 3D-ICs, where tolerances involving power are much tighter and any mistake can cause functional failures. At mature nodes, where there is more metal, power problems continue to be rare. But at advanced nodes, where chips are running at higher frequencies and still consuming the same or greater power... » read more

Solving Thermal Coupling Issues In Complex Chips
By Ann Mutschler - 10 Nov, 2022 - Comments: 0

Rising chip and packaging complexity is causing a proportionate increase in thermal couplings, which can reduce performance, shorten the lifespan of chips, and impact overall reliability of chips and systems. Thermal coupling is essentially a junction between two devices, such as a chip and a package, or a transistor and a substrate, in which heat is transferred from one to the other. If not... » read more

Balancing Power And Heat In Advanced Chip Designs
By Karen Heyman - 10 Nov, 2022 - Comments: 1

Power and heat use to be someone else's problem. That's no longer the case, and the issues are spreading as more designs migrate to more advanced process nodes and different types of advanced packaging. There are a number of reasons for this shift. To begin with, there are shrinking wire diameters, thinner dielectrics, and thinner substrates. The scaling of wires requires more energy to driv... » read more

What’s So Different About Interposer Signal Integrity?
By Kelly Damalou - 28 Oct, 2022 - Comments: 0

By Kelly Damalou and Pete Gasperini To achieve gains in power, performance, area, and cost, 3D-IC architectures are pushing electronics design to new limits. Silicon integration technology and associated devices have undergone an impressive evolution over the last several decades. Their development encourages technological advancement in applications like high-performance computing, Artificial... » read more

Which Foundry Is In The Lead? It Depends.
By Ed Sperling - 26 Oct, 2022 - Comments: 2

The multi-billion-dollar race for foundry leadership is becoming more convoluted and complex, making it difficult to determine which company is in the lead at any time because there are so many factors that need to be weighed. This largely is a reflection of changes in the customer base at the leading edge and the push toward domain-specific designs. In the past, companies like Apple, Google... » read more

Testing 2.5D And 3D-ICs
By Ed Sperling - 25 Oct, 2022 - Comments: 0

Disaggregating SoCs allows chipmakers to cram more features and functions into a package than can fit on a reticle-sized chip. But as Vidya Neerkundar, technical marketing engineer at Siemens EDA explains, there are challenges in accessing all of the dies or chiplets in a package. The new IEEE 1838 standard addresses that, as well as what to do when 2.5D and 3D-ICs are combined together in the ... » read more

Wafer Cleaning Becomes Key Challenge In Manufacturing 3D Structures
By Adele Hars - 20 Oct, 2022 - Comments: 0

Wafer cleaning, once a rather mundane task as simple as dipping wafers in cleaning fluid, is emerging as one of the top major engineering challenges for manufacturing GAA FETs and 3D-ICs. With these new 3D structures — some on the horizon but some already in high-volume manufacturing — semiconductor wafer equipment and materials suppliers in the wet cleaning business are at the epicenter... » read more

Coming In Hot: Requirements For Successful Thermal Management In 3D-IC
By Marc Swinnen - 03 Oct, 2022 - Comments: 0

As the speed, density, and capabilities of electronics have all increased, power has become a first order driver in almost all electronic systems. For instance, it’s well recognized that heat is often the number one limiting factor in 3D-IC design. High-speed chips stacked close together in a small housing cause things to heat up fast. One of the most common designer responses to overheating ... » read more

IC Architectures Shift As OEMs Narrow Their Focus
By Ed Sperling - 03 Oct, 2022 - Comments: 0

Diminishing returns from process scaling, coupled with pervasive connectedness and an exponential increase in data, are driving broad changes in how chips are designed, what they're expected to do, and how quickly they're supposed to do it. In the past, tradeoffs between performance, power, and cost were defined mostly by large OEMs within the confines of an industry-wide scaling roadmap. Ch... » read more
