  1. Assessment of the potential value return from research topicsFollow-up IRC actions from ITRS Maastricht, 04/07/06 July ITRS IRC Plenary inputs Incl. Three Scaling-Related Definitions Proposal, Rev 3 - 07/10/06

  2. Food for thought from the IRC • “Moore’s Law and its continuance is an economic rather than a technical statement” (Bernard Meyerson, chief technologist for IBM’s Systems & Technology Group). • “Clock frequency is not the [only] driver of system performance. You can get a better result by making tradeoffs to balance numerous aspects of performance” (adapted from Bernard Meyerson) • Classical Scaling -- the glue that connects Moore’s Law to performance – is enhanced by “equivalent scaling”. • There are additional ways to enhance economic and technical performance in conjunction with, or without, scaling.

  4. Three Scaling-Related Definitions Glossary Proposal • In order to clarify the IRC/TWG work on innovation and value, below is a proposal for three scaling-related definitions to be added to the Executive Summary Glossary in the 2006 Update: • Geometrical (constant field) Scaling (“More Moore”) refers to the continued shrinking of horizontal and vertical physical feature sizes of the on-chip logic and memory storage functions in order to improve density (cost per function reduction) and performance (speed, power) and reliability values to the applications and end customers. Examples (not exhaustive) are: a) horizontal half-pitch feature size (f^2) for density/cost; b) gate insulator thickness for speed and power performance; c) gate length for speed performance. Slowing of geometrical scaling reduces the rate at which the end applications and customers receive value benefits, requiring new “equivalent scaling” material and/or gate enhancements. • 1+) Equivalent Scalingwhich occurs in conjunction with, and also enables, continued Geometrical Scaling, refers to 3-dimensional device structure (“Design Factor”) Improvements plus other non-geometrical process techniques and new materials that affect the electrical performance of the chip. Examples (not exhaustive) are: a) horizontal or vertical function design factor (i.e. 3-dimensional capacitor and transistor designs); b) strained silicon in the transistor gate; c) flash memory electrical multi-bit-cell; d) high-K capacitor material for enhanced DRAM storage effectiveness; e) high-K transistor gate material substitutes for insulator thickness scaling; f) low-K chip-level interconnect material. Electrical equivalent scaling can enhance the value benefits of geometrical scaling.

  5. Three Scaling-Related Definitions Glossary Proposal [Definitions continued] 2) “More than Moore” refers to System-on-Chip (SOC) and/or System-in-Package (SIP) techniques and materials that provide additional chip, board, and system-level cost and performance value to the application and end customer, in conjunction with geometrical and equivalent scaling. Examples (not exhaustive) are: a) Large cache memory management architecture; b) Multi-core MPU architecture; c) on-chip logic plus software power management; d) stacked chips with through-vias for board-level density and power; e) Packaging low-K interconnect materials; and f) diverse Specialized Functionality such as AMS/RF, Image Sensors, Sensors/Actuators (including MEMS), Embedded Passives, etc.

  6. Three Scaling-Related Definitions Glossary Proposal and Examples Outline (including value to application/customer) • “More Moore” (MM) - Geometrical (constant field) scaling • Horizontal – half-pitch feature size (f2) (Moore’s Law, Function Size, Density) • Vertical – Gate Insulator Thickness (limit of Silicon Oxide) (Performance – speed, power) • Horizontal – Gate Length (Performance – speed, power) (1+).Equivalent scaling - Device Design and Process Techniques a) Vertical function design factor for density/cost, i.e. 3-D capacitor and transistor designs (Density/cost, Performance – speed, power) b) Strained Silicon (enhances gate current performance without gate insulator thickness reduction, while horizontal gate length continues to scale) MPU/ASIC (Performance – speed, power) c) Flash bit multi-cell (Density/cost) - Materials d) High K Capacitor DRAM (Performance – Storage Effectiveness/Reliability) e) High K Gate MPU/ASIC (enhances gate performance without vertical scaling, while horizontal gate length continues to scale) (Performance – speed, power) f) Low K Interconnect (Performance – speed, power) 2. ‘More Than Moore” (MtM) – Additional SOC and/or SIP , in conjunction with, or without, Geometrical and Equivalent chip scaling (chip, package, board, and system-level density/cost, performance - speed and power) • Large Cache • Multi-core • On-chip logic plus software power management • Stacked Chips with through-vias • Package Low-K Interconnect Material • Specialized Functionality • AMS/RF • Image Sensors • Sensors/Actuators (including MEMS) • Embedded Passives • Etc.

  7. Follow-up process • Start working now on the subject of “equivalent scaling parameters” • Topic to be included in the TWG meetings • Conference call early June • Joint conf call with IRC / some TWG chairs • Summer meeting • Half-day workshop IRC / selected TWG chairs • Contact with other consortia • MEMS Industry group (A.Allan) • iNEMI (A.Allan, JA.Carballo) • IEEE (P.Gargini)

  8. To be discussed in the TWG meetings • Former approach • Economic value through dimensional scaling • Proposed Approach • It is appropriate to evaluate the benefit of the addition of beyond Moore with respect to the customer. • The IRC wants the TWGs to think “out of the box” and look beyond geometrical (constant field) and equivalent scaling

  9. Possible topics that may interact with the economic value issue. • Working groups will continue to give input throughout 2006 for 2007 ITRS • What are other drivers? • How do we bring additional value to the customer - multi-dimensional and may need to think how best to guide research. • Questions for the CrossTWG meeting with the five teams [Interconnect, Design, PIDS, Wireless and A&P] TWG – • What value/benefit will pure continuing geometrical (constant field) and equivalent scaling bring ? • Which non-scaling (“More than Moore”) parameters will bring scaling-like value, such as: • meeting system performance/cost, or • bringing additional functionalities? • How to characterize / evaluate non-scaling parameters (of 2.) versus the continuing scaling approach? • Are there trade-offs involved between scaling and non-scaling parameters (e.g., frequency vs. # of multi-core processors)? • Is a cost-to-value tool needed to help evaluate trade-offs? What are the appropriate inputs/outputs for such a cost model? • The generic ITRS pre-competitive boundary timing is set by scaling and should be two technology generations (0.7x) from current technology level – • What is the pre-competitive boundary for the potential solution topic? • What is the necessary “critical mass” of interested companies?

  10. Possible TWG involvement preparation/proposals for July ITRS • Assy & Packaging • System integration white paper • Passive integration • Design • Extension of roadmap / system drivers (example Automotive HV power, Sensors) • System on Chip / network on Chip • PIDS / Design • extending MASTAR to system level • Interconnect • Optical • Passive integration • RF Wireless • Passive integration • …
