High performance logic scaling iedm comparison

High-Performance Logic Scaling (IEDM Comparison)

  • Benchmarks taken from IEDM publications; chose only technologies within 1-2 years of production.

  • IEDM Papers with leading-edge bulk (non-SOI) performance selected (Moto, TI, Intel).

  • Apparent discontinuity at year 2001 is an artifact due difference between IEDM publication date and ITRS production node date.

  • 17% historical trend is consistent with past IEDM data as well as with the previously used 2000 ITRS projection for local-clock frequency.


Scaling of different device performance factors

Scaling of Different Device Performance Factors

  • Channel-length scaling has the greatest impact on continued device performance.

  • Power supply voltage can not be scaled as aggressively as other device performance factors in order to maintain adequate overdrive (Vdd-VT).

  • New device technology improvements (SOI/low-temp/higher-mobility materials) will be needed to achieve required transconductance increase in later years (in addition to Tox scaling).


Scaling of different device hazard factors

Scaling of Different Device Hazard Factors

  • Gate-oxide effective E-field is increased by 50% by 2016.

  • Non-scalability of Tox/Lgate will increase short-channel effects. Project potential need for dual-gate SOI devices by the 2007 (65nm) node.

  • Voltage non-scalability will result in significantly increased lateral high-field effects (mitigation of these effects will be key device design challenge).


Feedback to other itrs twg groups

Feedback to Other ITRS TWG Groups

  • Design TWG:

    • Front-end performance can continue to scale at historical rate.

    • Both dynamic & static power dissipation must be dealt with at the design and system level (not through Vdd scaling).

    • Circuit/system design must now account for significantly higher sub-threshold and gate leakage current (devices approach bipolar-like characteristics).

  • Front-End-Process TWG:

    • Projection of Tox electrical requirements has been made.

    • Specification made for maximum gate-tunneling/junction leakage.

    • Scaling scenario proposed for high-K gate dielectrics.

    • Rsd allowed to become larger percentage of channel resistance; however, still require 2X reduction in parasitic Rsd value by 2016.

    • Scaling scenario for gate electrode depletion has been proposed (impacts metal gate introduction point).

    • Impact of parasitic fringe/overlap capacitance on device performance has been evaluated (impacts gate stack aspect ratio and composition).
