Where All The Semiconductor Investments Are Going


Companies and countries are funneling huge sums of money into semiconductor manufacturing, materials, and research — at least a half-trillion dollars over the next decade, and maybe much more — to guarantee a steady supply of chips and know-how to support growth across a wide swath of increasingly data-centric industries. The build-out of a duplicate supply chain that can guarantee capac... » read more

On-Chip Power Distribution Modeling Becomes Essential Below 7nm


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

Improving Reliability In Automobiles


Carmakers are turning to predictive and preventive maintenance to improve the safety and reliability of increasingly electrified vehicles, setting the stage for more internal and external sensors, and more intelligence to interpret and react to the data generated by those sensors. The number of chips inside of vehicles has been steadily rising, regardless of whether they are powered by elect... » read more

Taking Power Much More Seriously


An increasing number of electronic systems are becoming limited by thermal issues, and the only way to solve them is by elevating energy consumption to a primary design concern rather than a last-minute optimization technique. The optimization of any system involves a complex balance of static and dynamic techniques. The goal is to achieve maximum functionality and performance in the smalles... » read more

Solving Thermal Coupling Issues In Complex Chips


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


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

Weird Incidents Reveal L5 Challenges


A series of surprising, counterintuitive, and sometimes bizarre incidents reveal the challenges of achieving full Level 5 autonomy in self-driving vehicles, which are an increasingly common site in major cities. While it’s easy to dismiss such anecdotes as humorous glitches compared with the sobering accounts of autonomous tech-related injuries and fatalities, industry executives say these oc... » read more

Next Steps For Improving Yield


Chipmakers are ramping new tools and methodologies to achieve sufficient yield faster, despite smaller device dimensions, a growing number of systematic defects, immense data volumes, and massive competitive pressure. Whether a 3nm process is ramping, or a 28nm process is being tuned, the focus is on reducing defectivity. The challenge is to rapidly identify indicators that can improve yield... » read more

Legacy Tools, New Tricks: Optical 3D Inspection


Stacking chips is making it far more difficult to find existing and latent defects, and to check for things like die shift, leftover particles from other processes, co-planarity of bumps, and adhesion of different materials such as dielectrics. There are several main problems: Not everything is visible from a single angle, particularly when vertical structures are used; Various struc... » read more

Test Connections Clean Up With Real-Time Maintenance


Test facilities are beginning to implement real-time maintenance, rather than scheduled maintenance, to reduce manufacturing costs and boost product yield. Adaptive cleaning of probe needles and test sockets can extend equipment lifetimes and reduce yield excursions. The same is true for load board repair, which is moving toward predictive maintenance. But this change is much more complicate... » read more
