At the 2021 VLSI Technology Symposium, Imec presented on Ruthenium (Ru) and Molybdenum (Mo) as alternate Word Line (WL) materials for 3D NAND Flash “First Demonstration of Ruthenium and Molybdenum Word lines Integrated into 40nm Pitch 3D NAND Memory Devices”. I had an opportunity to interview one of the authors: Maarten Rosmeulen.… Read More
FinFETs devices are reaching their limits for scaling. Horizontal Nanosheets (HNS) are a type of Gate All Around (GAA) device that offers better scaling and performance per unit area. HNS is the logical next step from FinFETs because HNS processing is similar to FinFETs with a limited number of process changes required.

At the 2021 Symposium on VLSI Technology and Circuits in June a short course was held on “Advanced Process and Devices Technology Toward 2nm-CMOS and Emerging Memory”. In this article I will review the first two presentations covering leading edge logic devices. The two presentations are complementary and provide and excellent… Read More
On Monday morning at IEDM, Sri Samavedam of Imec opened the technical program with a plenary talk entitled “Future Logic Scaling: Towards Atomic Channels and Deconstructed Chips”. I am not generally a fan of plenary talks, I think the presenters often try to cover too much in their talks and end up not providing enough detail to be… Read More
The 2020 VLSI Technology Symposium was held as a virtual conference from June 14th through June 19th. At the symposium Imec gave an interesting paper on Monolithic CFET and I had a chance to interview one of the authors, Hiroaki Arimura.
It is well known in the industry that FinFETs (FF) are reaching the end of their scaling life. Samsung… Read More
At SEMICON West, Applied Materials announced a new selective gap fill tool to address the growing resistance issues in interconnect at small dimensions. I had the opportunity to discuss this new tool and the applications for it with Zhebo Chen global product manager in the Metal Deposition Products group at Applied Materials.… Read More
On Thursday July 9 Imec held a virtual technology forum. Imec is one of the premier research organizations working on semiconductor technology and their forums are always interesting. My area of interest is process technology and the following are my observation in that area from the forum.

Luc Van Den Hove is the… Read More
The 2020 VLSI Technology Symposium was held as a virtual conference from June 14th through June 19th. At the symposium Imec gave an interesting paper on Buried Power Rails (BPR) and I had a chance to interview one of the authors, Anshul Gupta.
As logic devices continue to scale down metal pitch is reaching a limit. Imec defines a pitch… Read More
Moore’s Law has been about device density, specifically transistor density, increasing every certain number of years. Although cost is the most easily grasped advantage, there are two other benefits: higher performance (speed) and reduced power. When these benefits are compromised, they can also pose a scaling limitation.
Corona Curtails already quiet SPIE Litho conference
Our best guess is that attendance was off by 30% from last years SPIE conference due to a lack of travelers from many Asian areas obviously out of Corona fear. Even Intel, which is a few miles away was a virtual no-show with a mass cancellation.
More importantly, virtually all after… Read More
