Our friends at Threshold Systems have a new ONLINE class that may be of interest to you. It’s an updated version of the Advanced CMOS Technology class held last February. This is normally a classroom affair but to accommodate the recent COVID-19 travel restrictions it is being offered virtually.
As part of the previous class we did… Read More
The relentless drive in the semiconductor industry for smaller, faster and cheaper integrated circuits has driven the industry to the 10 nm node and ushered in a new era of high-performance three-dimensional transistor structures. The speed, computational power, and enhanced functionality of ICs based… Read More
Our friends at Threshold Systems have a new class that may be of interest to you. It’s an updated version of the Advanced CMOS Technology class held last May. As part of the previous class we did a five part series on The Evolution of the Extension Implant which you can see on the Threshold Systems SemiWiki landing page HERE. And… Read More
Part 4 of this series discussed how a transistor Extension could be fabricated in a planar device without using an implant operation, and is instead formed using a preferential etch followed by a selective epitaxial deposition. This final installment of the series will present the formation of an Extension in a FinFET transistor… Read More
Perhaps the most innovative and effective Extension implant does not involve an implant at all, but is instead an etch followed by a selective epitaxial deposition.
In this Extension fabrication methodology the Source/Drains regions in a planar device are etched away in the normal fashion to accommodate the replacement Source/Drain… Read More
The 3D character of FinFET transistor structures pose a range of unique fabrication problems that can make it challenging to get these devices to yield. This is especially true for the all-important Extension implant that is put in place just prior to the nitride spacer formation.
The Extension implant is a central component of… Read More
