2. Fall 2006 ECS S.E. Thompson 2 What is Moore’s Law

3. Fall 2006 ECS S.E. Thompson 3 Moore’s Law According to Moore: ~ 0.7X linear scale factor 2X increase in density / 2 years Lower cost Higher performance (~30% / 2 years) At severe competitive disadvantage if don’t have newer technology Has been going on for 40 years and will continue “somewhat” for another decade 1 st signs of this being no longer valid is some markets

5. Fall 2006 ECS S.E. Thompson 5 CLASS GOAL This class will expose the student to state of the art technology issues and industrial team problem solving. The class will provide links between the short-term topics, which will certainly be in production during the next 10 years such as nano- scale MOSFET, strained Si, high k gates to far- reaching topics, which are well ahead or off the main stream, offering high Potential. Some of these topics will include carbon nanotubes, molecular electronics and single electron devices for logic applications.

6. Fall 2006 ECS S.E. Thompson 6Relevance: At present silicon technology is “IT” however Moore’s Law will slow over the next decade and will have a profound effect on industry and university business and engineering jobs. The slowing should not be viewed as an end just a new phase in the $300B microelectronic industry were the rules of business change.

14. Fall 2006 ECS S.E. Thompson 14 CLASS / Team Project (assigned Mid Year) Compare post CMOS replacement device options to the MOSFET (most successful device technology) Which if any post CMOS device options should the microelectronics focus on as a MOSFET replacement? Recommendation should be based – Historical and projected future MOSFET trends. – On quantum, statistical mechanics, and device limits. – Potential advantage of post CMOS device option. –Class homework will help shape project – Suggestions: Start with a good literature search. Use excellent free service of electronic journals on-line. Use Mathlab for calculations and graphs. Group divided into 10 Teams

See me. Will be handled on case by case basis Student with disability: Students requesting classroom accommodation must first register with the Dean of Student Office. The Dean of Students Office will provide documentation to the student who must then provide this documentation to the instructor when requesting accommodations. Expect on time to class.
