3D-IC Reliability Degrades With Increasing Temperature
By Ann Mutschler - 14 Dec, 2022 - Comments: 0

The reliability of 3D-IC designs is dependent upon the ability of engineering teams to control heat, which can significantly degrade performance and accelerate circuit aging. While heat has been problematic in semiconductor design since at least 28nm, it is much more challenging to deal with inside a 3D package, where electromigration can spread to multiple chips on multiple levels. “Be... » read more

IC Stresses Affect Reliability At Advanced Nodes
By Ann Mutschler - 08 Dec, 2022 - Comments: 1

Thermal-induced stress is now one of the leading causes of transistor failures, and it is becoming a top focus for chipmakers as more and different kinds of chips and materials are packaged together for safety- and mission-critical applications. The causes of stress are numerous. In heterogeneous packages, it can stem from multiple components composed of different materials. “These materia... » read more

Improving Concurrent Chip Design, Manufacturing, And Test Flows
By Ann Mutschler - 28 Nov, 2022 - Comments: 0

Semiconductor design, manufacturing, and test are becoming much more tightly integrated as the chip industry seeks to optimize designs using fewer engineers, setting the stage for greater efficiencies and potentially lower chip costs without just relying on economies of scale. The glue between these various processes is data, and the chip industry is working to weave together various steps t... » 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

Chip Design Shifts As Fundamental Laws Run Out Of Steam
By Ann Mutschler - 31 Oct, 2022 - Comments: 12

Dennard scaling is gone, Amdahl's Law is reaching its limit, and Moore's Law is becoming difficult and expensive to follow, particularly as power and performance benefits diminish. And while none of that has reduced opportunities for much faster, lower-power chips, it has significantly shifted the dynamics for their design and manufacturing. Rather than just different process nodes and half ... » read more

Bespoke Silicon Rattles Chip Design Ecosystem
By Ann Mutschler - 19 Oct, 2022 - Comments: 0

Bespoke silicon developers are shaking up relationships, priorities, and methodologies across the semiconductor industry, creating demand for skills that cross traditional boundaries, and driving new business models that leverage these enormous investments. Bespoke silicon designers today are a rare breed, capable of understanding the unique requirements of a specific domain, as well as a gr... » read more

Designing A Better Clock Network
By Ann Mutschler - 13 Oct, 2022 - Comments: 0

Laying the proper clock network architecture foundation makes all the difference for the best performance, power, and timing of a chip, particularly in advanced node SoCs packed with billions of transistors. Each transistor, which acts like a standard cell, needs a clock. An efficient clock network should ensure the switching transistors save power. In today’s advanced nodes, when a design... » read more

EVs Raise Energy, Power, And Thermal IC Design Challenges
By Ann Mutschler - 06 Oct, 2022 - Comments: 0

The transition to electric vehicles is putting pressure on power grids to produce more energy and on vehicles to use that energy much more efficiently, creating a gargantuan set of challenges that will affect every segment of the automotive world, the infrastructure that supports it, and the chips that are required to make all of this work. From a semiconductor standpoint, improvements in th... » read more

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

Within the semiconductor ecosystem, there are a number of dynamics pointing to the need for new ways of partnering in more meaningful ways that bring resiliency to the global semiconductor supply chain. One of these is the move to bespoke silicon, stemming from a shift in the companies that create most SoCs today -- the hyperscalar cloud providers. These market leaders know their workloads so w... » read more
