How FinFET Device Performance Is Affected By Epitaxial Process Variations


By Shih-Hao (Jacky) Huang and Yu De Chen As the need to scale transistors to ever-smaller sizes continues to press on technology designers, the impact of parasitic resistance and capacitance can approach or even outpace other aspects of transistor performance, such as fringing capacitance or source drain resistance. The total resistance in a device is comprised of two components: internal re... » read more

Effects Of A Random Process Variation On The Transfer Characteristics Of A Fundamental Photonic Integrated Circuit Component


Silicon photonics is rapidly emerging as a promising technology to enable higher bandwidth, lower energy, and lower latency communication and information processing, and other applications. In silicon photonics, existing CMOS manufacturing infrastructure and techniques are leveraged. However, a key challenge for silicon photonics is the lack of mature models that take into account known CMOS pr... » read more

Node Within A Node


Enough margin exists in manufacturing processes to carve out the equivalent of a full node of scaling, but shrinking that margin will require a collective push across the entire semiconductor manufacturing supply chain. Margin is built into manufacturing at various stages to ensure that chips are manufacturable and yield sufficiently. It can include everything from variation in how lines are... » read more

Controlling Variability And Cost At 3nm And Beyond


Richard Gottscho, executive vice president and CTO of Lam Research, sat down with Semiconductor Engineering to talk about how to utilize more data from sensors in manufacturing equipment, the migration to new process nodes, and advancements in ALE and materials that could have a big impact on controlling costs. What follows are excerpts of that conversation. SE: As more sensors are added int... » read more

Controlling IC Manufacturing Processes For Yield


Equipment and tools vendors are starting to focus on data as a means of improving yield, adding more sensors and analysis capabilities into the manufacturing flow to circumvent problems in real time. How much this will impact the cost of developing complex chips at leading-edge nodes, and in 2.5D and 3D-IC packages, remains to be seen. But the race to both generate data during manufacturing ... » read more

The Mighty Sensor In The Fab


The days of scheduled maintenance on fab equipment are coming to an end. In fact, the entire service model as we know it is about to undergo a mammoth change. The addition of more sensors into manufacturing equipment may seem like an evolutionary step, but the impact is going to be much more significant than it might appear. Rather than just alerting fab managers or equipment makers when a p... » read more

Process Variation And Aging


Semiconductor Engineering sat down to discuss design reliability and circuit aging with João Geada, chief technologist for the semiconductor business unit at ANSYS; Hany Elhak, product management director, simulation and characterization in the custom IC and PCB group at Cadence; Christoph Sohrmann, advanced physical verification at Fraunhofer EAS; and Naseer Khan, vice president of sales at M... » read more

Why Chips Die


Semiconductor devices contain hundreds of millions of transistors operating at extreme temperatures and in hostile environments, so it should come as no surprise that many of these devices fail to operate as expected or have a finite lifetime. Some devices never make it out of the lab and many others die in the fab. It is hoped that most devices released into products will survive until they be... » read more

Carmakers To Chipmakers: Where’s The Data?


The integration of electronics into increasingly autonomous vehicles isn't going nearly as smoothly as the marketing literature suggests. In fact, it could take years before some of these discrepancies are resolved. The push toward full autonomy certainly hasn't slowed down, but carmakers and the electronics industry are approaching that goal from very different vantage points. Carmakers and... » read more
