Advanced IC technologies, 5nm and 7nm FinFET design and stacked packaging, are enabling massive levels of integration of super-fast circuits. These in turn enable much of the exciting new technology we hear so much about: mobile gaming and ultra-high definition mobile video through enhanced mobile broadband in 5G, which requires… Read More
IEDM 2019 – TSMC 5nm Process
IEDM is in my opinion the premiere conference for information on state-of-the-art semiconductor processes. In “My Top Three Reasons to Attend IEDM 2019” article I singled out the TSMC 5nm paper as a key reason to attend.
IEDM is one of the best organized conferences I attend and as soon as you pick up your badge you are handed a memory… Read More
My Top Three Reasons to Attend IEDM 2019
The International Electron Devices Meeting is a premier event to learn about the latest in semiconductor process technology. Held every year in early December is San Francisco this years conference will be held from Decembers 7th through December 11th. You can learn more about the conference at their web site here.
This is a must… Read More
Semicon West 2019 – Day 2
Tuesday July 9th was the first day the show floor was open at Semicon. The following is a summary of some announcements I attended and general observations.
AMAT Announcement
My day started with an Applied Materials (AMAT) briefing for press and analysts where they announced “the most sophisticated system they have ever released”.… Read More
400G Ethernet test chip tapes-out at 7nm from eSilicon
Since the beginning of May eSilicon has announced the tape-out of three TSMC 7nm test chips. The first of these, a 7nm 400G Ethernet Gearbox/Retimer design, caught my eye and I followed up with Hugh Durdan, their vice president of strategy and products, to learn more about it. Rather than just respin their 56G SerDes, they decided… Read More
IC to Systems Era
One of my favorite EDA disruptions is the Siemens acquisition of Mentor, pure genius. Joe Sawicki now runs the Mentor IC EDA business for Siemens so we will be seeing him at more conferences and events than ever before. Joe did a very nice keynote at the recent U2U conference that I would like to talk about before we head to the 56thDAC… Read More
Achieving a Predictable SignOff in 7nm
Designing with advanced-nodes FinFETs such as 7nm node involves a more complex process than prior nodes. As secondary physical effects are no longer negligible, the traditional margin-based approach applied at various design abstraction levels is considered ineffective. Coupled with the increase of device counts, failing… Read More
The Evolution of the Extension Implant Part IV
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 Evolution of the Extension Implant Part III
The problem of traditional FinFET Extension Implant doping concerns the awkward 3-dimensional structure of the fin. Because the Extension Implant defines the conductive electrical pathway between the Source/Drains and the undoped channel portion of the fin, it is essential that the fin be uniformly doped all three of its surfaces… Read More
The Evolution of the Extension Implant Part II
The use of hard masks instead of photoresist for the Extension implant is an effective way to optimize the amount of dopant that is retained along the fin sidewalls for those fins that border along photoresist edges (as discussed in Part 1 of this series).
However, hard masks do nothing to address the dominant problem driving steeper… Read More
