Re: Can DSA save the day?
resistion   3/2/2014 7:35:27 AM
DSA is like a more cost-effective multiple patterning method, particularly good for "more than double" patterning of memory arrays or generally gridded features, without using iterations of spacer deposition and etching. There is a more advanced DSA version even for square arrays of contact holes, using triblock (instead of diblock) copolymers. This one-step multiplication is also the same motivation behind the 3D vertical NAND scheme. If planar floating gate NAND wants to (or even could) keep on going, most likely DSA would be a prime patterning candidate. It conceivably could be cheaper than 3D vertical NAND, but we need undisclosed numbers to compare.

Now of course, like any wannabe technology, like EUV or 3D vertical NAND, there are a number of issues to clear out first. For DSA the key one is natural defectivity and non-uniformity. And besides that, the ability to align repeatably (to an edge). Also, is it too thin to be a reliable etch mask?

It's an interesting stopgap that postpones the end of the line for Moore's Law. That's incredibly valuable of course, but doesn't change the need to continue the search for the next device -- the successor to the MOS transistor.

When transistors are on and you can count the electrons as they go by, we will be at the end.  At that point, something has to change radically.  Maybe photons instead of electrons.

Can DSA save the day?

I've heard a bit about DSA from Imec last fall and it was big in the SPIE Litho proram this week. But when I asked people they said it was more of an additive helping technology rather than a significant replacement for something like EUV, so...

Good to see that MIT research will help Moore's Law continue but the bigger question is when will the saturation happen. For how long we will be able to shrink the transistor size ? Parts Search

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
