Systematic Yield Issues Now Top Priority At Advanced Nodes


Systematic yield issues are supplanting random defects as the dominant concern in semiconductor manufacturing at the most advanced process nodes, requiring more time, effort, and cost to achieve sufficient yield. Yield is the ultimate hush hush topic in semiconductor manufacturing, but it's also the most critical because it determines how many chips can be profitably sold. "At older nodes, b... » read more

Adopting Predictive Maintenance On Fab Tools


Predictive maintenance, based on more and better sensor data from semiconductor manufacturing equipment, can reduce downtime in the fab and ultimately cut costs compared with regularly scheduled maintenance. But implementing this approach is non-trivial, and it can be disruptive to well-honed processes and flows. Not performing maintenance quickly enough can result in damage to wafers or the... » read more

High Voltage Testing Races Ahead


Voltage requirements are increasing, especially for the EV market. Even devices that might be considered relatively low voltage, such as display drivers, are now pushing past established baselines. While working with high voltages is nothing new — many engineers can recall yellow caution tape in their workplaces — the sheer number and variety of new requirements have made testing at high... » read more

Cybersecurity Risks Of Automotive OTA


Modern vehicles increasingly resemble supercomputers on wheels, with many electronic control units (ECUs) networked together as increasingly sophisticated software is installed and updated. Similar to smartphones, vehicle OEMs will contact vehicle owners remotely about operating system updates that add new features and/or fixes, as well as software bugs and vulnerabilities. But all of this h... » read more

Indoor Gas Sensors Proliferate With Better Standards


The gas sensor market is rapidly expanding, driven by increased concerns about indoor air quality and better technology for detecting and measuring it. Indoor air quality sensing targets gases and concentrations that differ — with some overlap — from outside. But until the pandemic, which largely coincided with a flood of new research about what is toxic to people and animals, this has b... » read more

Why Better Mapping Technology Is Critical To Autonomous Vehicles


Autonomous cars find the way to their destination using a number of critical technologies, including some version of a global position system and a central brain to interpret that and other data. But many of those technologies are not reliable or accurate enough today, and may not be for years to come. There are numerous reports of vehicles missing their stop, or trucks being guided into all... » read more

Making Chips Yield Faster At Leading-Edge Nodes


Simulation for semiconductor manufacturing is heating up, particularly at the most advanced nodes where data needs to be analyzed in the context of factors such as variation and defectivity rates. Semiconductor Engineering sat down with David Fried, corporate vice president of computational products at Lam Research, to talk about what's behind Lam's recent acquisition of Esgee Technologies, ... » read more

Improving Concurrent Chip Design, Manufacturing, And Test Flows


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

Is UCIe Really Universal?


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

EDA Tools For Quantum Chips


Commercially viable quantum computers are at least several years away, but some researchers already are questioning whether existing EDA tools will be sufficient for designing quantum chips and systems. That’s because quantum design requirements at times transcend classical rules about materials, temperature, and structure — rules that are foundational for the majority of EDA products on th... » read more
