Are Chips Getting More Reliable?


The semiconductor industry is making huge progress in understanding the causes and telltale signs of circuit aging and irregular behavior. But are devices actually getting more reliable? The answer depends on a number of factors, none of which is easily measured. To be sure, circuits are much better designed and inspected than in the past, and the individual components are printed more accur... » read more

Interconnects Emerge As Key Concern For Performance


Interconnects are becoming increasingly challenging to design, implement and test as the amount of data skyrockets and the ability to move that data through denser arrays of compute elements and memories becomes more difficult. The idea of an interconnect is rather simple, but ask two people what constitutes an interconnect and you're likely to get very different answers. Interconnects are e... » read more

Moore’s Law Enters The 4th Dimension


The basic idea that more transistors are better hasn't changed in more than half a century. In fact, the overriding theme of a number of semiconductor conferences this month is that we will never have enough compute capability or storage capacity. In the past, when the number of transistors in a given area actually did double every 18 to 24 months, increasing density per square millimeter fo... » read more

Monitoring Chips After Manufacturing


New regulations and variability of advanced process nodes are forcing chip designers to insert additional capabilities in silicon to help with comprehension, debug, analytics, safety, security, and design optimization. The impact of this will be far-reaching as the industry discusses what capabilities can be shared between these divergent tasks, the amount of silicon area to dedicate to it, ... » read more

Redefining The Power Delivery Network


Reliably getting power around a package containing multiple dies, potentially coming from multiple sources, or implemented in diverse technologies, is becoming much more difficult. The tools and needed to do this in an optimized manner are not all there today. Nevertheless, the industry is confident that we can get there. For a single die, the problem has evolved slowly over time. "For a ... » read more

Preparing For A Barrage Of Physical Effects


Advancements in 3D transistors and packaging continue to enable better power and performance in a given footprint, but they also require more attention to physical effects stemming from both increased density and vertical stacking. Even in planar chips developed at 3nm, it will be more difficult to build both thin and thick oxide devices, which will have an impact on everything from power to... » read more

Power And Performance Optimization At 7/5/3nm


Semiconductor Engineering sat down to discuss power optimization with Oliver King, CTO at Moortec; João Geada, chief technologist at Ansys; Dino Toffolon, senior vice president of engineering at Synopsys; Bryan Bowyer, director of engineering at Mentor, a Siemens Business; Kiran Burli, senior director of marketing for Arm's Physical Design Group; Kam Kittrell, senior product management group d... » read more

Chiplet Reliability Challenges Ahead


Assembling chips using LEGO-like hard IP is finally beginning to take root, more than two decades after it was first proposed, holding the promise of faster time to market with predictable results and higher yield. But as these systems of chips begin showing up in mission-critical and safety-critical applications, ensuring reliability is proving to be stubbornly difficult. The main driver fo... » read more

Creating Better Models For Software And Hardware Verification


Semiconductor Engineering sat down to discuss what's ahead for verification with Daniel Schostak, Arm fellow and verification architect; Ty Garibay, vice president of hardware engineering at Mythic; Balachandran Rajendran, CTO at Dell EMC; Saad Godil, director of applied deep learning research at Nvidia; Nasr Ullah, senior director of performance architecture at SiFive. What follows are excerpt... » read more

Rethinking Competitive One Upmanship Among Foundries


The winner in the foundry business used to be determined by who got to the most advanced process node first. For the most part that benchmark no longer works. Unlike in the past, when all of the foundries and IDMs competed using basically the same process, each foundry has gone its own route. This is primarily due to the divergence of end markets, and the realization that as costs increase, ... » read more
