What Can Accelerate 3D Semiconductor Manufacturing?

In the beginning of this decade there was a lot of buzz around 3D chip manufacturing. Many EDA tools were developed to facilitate semiconductor designs in 3D space. Naturally, we are moving to the edge on 2D without much room to further squeeze transistors and interconnect. However, lately I haven’t heard much about 3D products. What happened? All I could guess is that there must be manufacturing difficulties, yield and ramp-up issues and the like. Then, last week I got to hear from IHS iSuppli that NAND Flash memories are moving into 3D manufacturing. That was interesting news, so I looked further into one of the latest articles on iSuppli website written by Dee Robinson, here. It’s understandable because NAND Flash memory is the fastest in reaching that limit of finer geometry in 2D production, however I was disappointed after learning that 3D NAND Flash will take four years from now to reach about 65% (by 2017) of total NAND Flash share. Why should it take so long? read more…

Rapid Yield Optimization at 22nm Through Virtual Fab

Remember? During DAC 2013 I talked about a new kind of innovation: A Virtual Fabrication Platform, SEMulator3D, developed by COVENTOR. Now, to my pleasant surprise, there is something to report on the proven results from this platform. IBM, in association with COVENTOR, has successfully implemented a 3D Virtual Fabrication methodology to rapidly improve the yield of high performance 22nm SOI CMOS technology.

The CTO-Semiconductor of COVENTOR, Dr. David M. Fried was in attendance while IBM’s Ben Cipriany presented an interesting paper on this work at The International Conference on Simulation of Semiconductor Processes and Devices (SISPAD 2013). The paper is available at the link “IBM, Coventor present 22nm Virtual Fabrication Success at SISPAD” at the COVENTOR website.

Coventor launches ‘Virtual fabrication’ software

Micro Manufacturing

Coventor Inc., a supplier of virtual fabrication solutions for semiconductor devices and micro-electromechanical systems (MEMS), announced the availability of its SEMulator3D 2013 “virtual fabrication” software platform.

SEMulator3D 2013 offers physical accuracy and predictive modeling capabilities to process development and integration, according to the company. The software makes “virtual fabrication” available to the broader semiconductor ecosystem, helping reduce silicon learning cycles and the billions of dollars spent reaching manufacturing readiness, the Cary, N.C.-based company reports.

New Process Modeling Mechanism

by Bryon Moyer
EE Journal

Simulation is all about using the simplest possible modeling technique that gives enough accuracy to make the results useful. Simplicity typically speeds up simulation – and, in many cases, makes the problem tractable in the first place.

But at some point, the unnecessary details that the modeling abstractions hide become necessary. At that stage, if you’re lucky, you can tweak your modeling technique to allow for the now-important effects. But eventually you may to have to take a new approach.

Physical process simulation

One of things I have learned is that you cannot understand everything associated with designing and making of semiconductors. The physics associated with the manufacturing process, while highly interesting, involves a lot more material science than I care to learn. But for others this is the core of their business and I learned a lot more about it when I spoke to David Fried, the CTO of Coventor.

Now, while I cannot understand many of the details behind their product, the rational for it is blazingly clear. Let me start in the land of functional verification. We do simulation for a number of reasons. The first is that it is too expensive to try something out in silicon before you have a reasonable confidence that it will work. The second is that once you have created the device, you have limited visibility into what is going on inside the chip. So, simulation serves both purposes. First you can ensure that you only go to silicon when you are confident enough that it will work and secondarily, the simulation provides you much more visibility into what is happening so that debug is a lot simpler.
