1 Nano Science Activities Technion – Israel Institute of Technology Electrical Engineering Department

2 The Center was established in 1979 by the late Professor I. Kidron and Professor A. Bar-Lev as part of the Technion's Department of Electrical Engineering. Since its establishment it has advanced to the forefront of Israel's technological community making a critical contribution to the country'' scientific, industrial and economic development. Founders Microelctronics in Israel Intel Israel Tower semiconductors ……. You can find many of our graduates at key positions in the silicon valley The experience we build upon

3 What is our vision here ? Take the set of tools that every electrical engineer has Create a similar set of tools but in the context of nano- electronics The rest will happen by itself You will find many of our graduates at key positions in the carbon valley Making use of our experience
