"Recently TSMC said at 20 nm there are no significant differences [in process optimizations], but I don't believe that," said Subramanian Iyer, an IBM fellow and chief technologist in its microelectronics division. "I believe at same node you can have two [different variations]," he said in a keynote here.
...
Iyer of IBM said TSMC's decision to offer one flavor of 20 nm may have been more of an economic than a technical decision.
...
The historic challenge of offering variations of a process is that each one requires a different set of unique and complex features added to the base process, said Iyer of IBM. "All the little features we have are like drugs, we can't drop them without severe withdrawal symptoms," he said.
...
"This 3-D technology is really powerful and we will see it in many places," said Iyer of IBM which has already made working prototypes of server processors in TSV stacks with DRAMs.
CPUs have 8-12 cores now "and want to go to 24 cores" with 3-D IC modules that stack DRAMs and heat sinks. IBM is also interested in "systems on an interposer," 2.5-D modules that surround a processor with memory chips on a silicon substrate with de-coupling capacitors to improve power regulation, he said.
"There's a lot of good stuff happening in this area that will make a significant difference, and the same concepts are applicable in the mobile space with similar advantages," he added.
...
The bad news is "as you go to smaller nodes the benefits of scaling are being eroded significantly," said Iyer of IBM.
The culprit is the lack of any new lithography techniques. Today's 193 nm immersion lithography systems are being asked to create 22 and even 14 nm features.
"This does not come free, the costs are becoming formidable," Iyer said. "Complex patterning solutions are the cause of the angst we are having," he added.
...
"Until we get to 7 nm or so there are no fundamental issues we see," said Iyer.

The details are being worked out, says Subramanian Iyer, IBM's Manager, Embedded Chip Development.
...
Benefits will accrue to IBM, says Iyer. "The lab will help us network among bright students and attract the best talent. ... Iyer, an IIT alumnus (Electrical Engineering, class of 1977), is currently working on Blue Gene, which, IBM claims, will be the world's most powerful computer when it's completed in 2005.

Subramanian S. Iyer is IBM at the Systems & Technology Group, and is responsible for technology strategy and competitiveness, embedded memory and Three-Dimensional Integration. e obtained his B.Tech in Electrical Engineering at the Indian Institute of Technology, Bombay, and his M.S. and Ph.D. in Electrical Engineering at the University of California at Los Angeles. He joined the IBM T. J. Watson Research Center in 1981 and was manager of the Exploratory Structures and Devices Group till 1994, when he founded SiBond LLC to develop and manufacture Silicon-on-insulator materials. He has been with the IBM Microelectronics Division since 1997. Dr. Iyer has received two Corporate awards and four Outstanding Technical Achievement awards at IBM for the development of the Titanium Salicide process, the fabrication of the first SiGe Heterojunction Bipolar Transistor, the development of embedded DRAM technology and the development of eFUSE technology. His current technical interests and work lie in the area of 3-dimensional integration for memory sub-systems and the semiconductor roadmap. He is a Master Inventor. He received the Distingushed Aluminus award from the Indian Institute of Technology, Bombay in 2004. Dr. Iyer has authored over 175 articles in technical journals and several book chapters and co-edited a book on bonded SOI. He has served as an Adjunct Professor of Electrical Engineering at Columbia University, NY. He is the recepient of the 2012 IEEE Daniel Nobel award for emerging techologies In his spare time, he studies Sanskrit and role of Indic languages, traditions and culture in different parts of the world.

"Our primarily goal is to provide technology that goes into IBM products," said Subramanian Iyer, chief technologist for the Semiconductor Research and Development Center within IBM's systems and technology group.
Previously, like many chipmakers, the company was developing its processes on its own.
...
"We had the option" for bringing out high-k at 45nm, Iyer said."It was working."
IBM and its partners are also working on 22nm technology.
