2007 Transition table

2009 Transition table proposed TechnologyStatusReasonComment RTDoutNo viable logic functionality Has been tracked for multiple revisions Bi-layer tunneling devices InSignificant theoretical work in NRI Band to band tunneling devices In NEMSIn RSFQPossible future device

New topics for discussion –Should we broaden the “CMOS extension” table to include Low Power” and “Low Standby Power” entries? –Pros Would align better with ITRS System Drivers Would reflect motivation of much research –Con Would significantly complicate chapter organization Would be orthogonal to the historical “tracking” function of the Table

Technology Entries(1) FET extensions –Low dimension Channel replacement category CNTFETS and Nanowire FETS Discuss CNTFETs with PIDs –High mobility channel replacements Send III-V and Ge to PIDs Graphene Nanoribbon devices

SETs Move to Table 2 –Some recent work still suggests logic applications –Emphasize non logic applications (recognition) –SETs have been around for a long time –Stray charge will always be problem Nature of Nanotechnology advance online

Molecular devices Move to table 2 Emphasize potential applications in crossbar architectures, CMOL Recent progress will be reviewed Some people believe strongly that the technology has great potential

Ferromagnetic and spin transistor Merge categories and move to table 2 Emphasize non volatile functionality Include MQCA and domain wall applications STTRAM research is driving progress in materials and process

Band to band tunneling devices Include as a category in table 1 ??? Include other steep SS devices Most devices suffer from low I sat or high V d CNT tunnel FETs

Resonant Tunnel Diodes Recommend moving to transition table Pros –Not much recent progress for any logic application Cons –It is an interesting device with NDR –Many people feel strongly about it

Multiferroic and magnetoelectric devices Include multiferroic tunnel junctions, magnetoelectric amplifiers, magnetoelectric drivers and detectors Significant progress in RT mutiferroic and magnetoelectric materials e.g. BFO

Single Electron devices Remove from table 1 -keep in table 2 –Active research for Boolean applications quantum dots –Potential Non Boolean logic applications such as image recognition still receiving attention –Stray charge still an issue

Potential solution table for carbon based nanoelectronics Build on ITRS “potential solution” format Separate into material driven requirements and novel device driven requirements Tie closely and directly to ERM

ERM table of applications

Proposed structure - table 1

Proposed structure –table 2

Coupling to ERM

Writing volunteers People or groups to research and write text for one or more of the technology entries –Need informed but unbiased contributors
