Building Predictive And Accurate 3D Process Models


Process engineers and integrators can use virtual process modeling to test alternative process schemes and architectures without relying on wafer-based testing. One important aspect of building an accurate process model is to ensure that the model is calibrated. Having a calibrated model is important, since it provides assurance to the process integrators and engineers that the model will refle... » read more

How The Special Snowflake Problem Impacts Asset Management—And What You Can Do


Asset managers face ongoing pressure to maximize the reliability and efficiency of their installations. Monitoring a single site is challenging enough, but when management spans two or more sites, additional complexities are typically introduced. The core problem? No two sites are the same. They differ not only in geographic location, but also usually in age, schematic configuration, maintenanc... » read more

DRAM, 3D NAND Face New Challenges


It’s been a topsy-turvy period for the memory market, and it's not over. So far in 2020, demand has been slightly better than expected for the two main memory types — 3D NAND and DRAM. But now there is some uncertainty in the market amid a slowdown, inventory issues and an ongoing trade war. In addition, the 3D NAND market is moving toward a new technology generation, but some are enc... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs Apple has launched a new Apple Watch and iPad. Missing from the announcement was the iPhone 12, which may appear next month, according to Krish Sankar, an analyst at Cowen. What was interesting about this week’s announcement? Apple unveiled the iPad Air with the A14 Bionic, Apple’s most advanced chip. “Apple revealed the new 8th gen iPad (starting at $329) powered by ... » read more

How Secure Is The Package?


Advanced packaging is a viable way of extending the benefits of Moore's Law without the excessive cost of shrinking everything to fit on a single die, but it also raises some issues about security for which there are no clear answers at the moment. OSATs and foundries have been working the kinks out of how to put the pieces together in the most cost-effective and reliable way for the better ... » read more

Upturn Seen In Semi Equipment Biz


Business continues to get better in the semiconductor equipment sector. VLSI Research, for one, has raised its forecast in the arena. But there is still some uncertainty amid mixed growth for semiconductors, trade wars and other factors. After a downturn in 2019, the semiconductor equipment market expected an upturn in 2020. Then, the Covid-19 pandemic struck. Suddenly, a large percentage... » read more

Industry Pushes For Fab Tool Security Standards


The semiconductor industry is developing new cybersecurity standards for fab equipment in an effort to protect systems from potential cyberattacks, viruses, and IP theft. Two new standards are in the works, which are being formulated under the auspices of the SEMI trade group with leadership from chipmakers and others. Led by Intel and Cimetrix, the first standard deals with malware-free equ... » read more

Momentum Builds For Advanced Packaging


The semiconductor industry is stepping up its efforts in advanced packaging, an approach that is becoming more widespread with new and complex chip designs. Foundries, OSATs and others are rolling out the next wave of advanced packaging technologies, such as 2.5D/3D, chiplets and fan-out, and they are developing more exotic packaging technologies that promise to improve performance, reduce p... » read more

Neural Networks Without Matrix Math


The challenge of speeding up AI systems typically means adding more processing elements and pruning the algorithms, but those approaches aren't the only path forward. Almost all commercial machine learning applications depend on artificial neural networks, which are trained using large datasets with a back-propagation algorithm. The network first analyzes a training example, typically assign... » read more

A Mid-Year End Market Recovery For Semiconductors


Although the semiconductor chip and capital equipment markets performed well in the first half of 2020, many of the electronic equipment end markets struggled globally. World electronic equipment sales declined almost 10% in 2Q’20 vs. 2Q’19 (chart 1). Better mid-year end market demand However, world business conditions are improving. The global purchasing managers index, a measure of broa... » read more
