ITRS Table Definitions/Guidelines, Proposal Rev1, 7/11/00
• Technology Requirements Perspective- Near-Term Years : First Yr. Ref.+ 6 yrs F’cast (ex. 1999 through 2005), annually- Long-Term Years : Following 9 years (ex.: 2008, 2011, and 2014), every 3 years
• Technology Node : - General indices of technology development. - Approximately 70% of the preceding node, 50% of 2 preceding nodes. - Each step represents the creation of significant technology progress- Example: DRAM half pitches (2000 ITRS) of 180, 130, 90, 65, 45 and 33 nm*Year 2000 : Smallest 1/2 pitch among DRAM, ASIC, MPU, etc
• Year of Production: - The volume = *10K units (devices)/month. ASICs manufactured by same
process technology are granted as same devices- Beginning of manufacturing by *a company and another company starts
production within 3 months
• Technology Requirements Color :- : Manufacturable Solutions are NOT known
- : Manufacturable Solutions are known
- : Manufacturable Solutions exist, and they are being optimized
*Year 2000 : Red cannot exist in next 3 years (2000, 2001, 2002)***Year 2000 : Yellow cannot exist in next 1 year (2000)

** Exception: Solution NOT known, but does not prevent Production manufacturing

Summary of Key Assumption Proposed Changes [1999 ITRS vs. Sc.2.0 Proposal] (cont.- DRAM):
DRAM Assumptions:
a) Cell Area Factor Limits (from FEP TWG):
1999: 8x/1999 -> 6x/2002 -> 4.4x/2005 -> 3.0x/2011 -> 2.5x/2014
Sc.2.0: 8x/1999-2004, 6x/2005-2010, 4x/2011-16b) Cell Array Efficiency Limit Trends (from FEP, Nikkei Microdevices):
1999: Intro: 1999/70% --> 2016/75%
Sc.2.0: Intro: 1999/70% --> 2016/75%1999: Production 1999/53% --> 2016/57%
Sc.2.0: Production 1999/53% --> 2016/58%c) Litho Field Size (from Litho TWG):
1999: 4x Magnification, 6-inch Reticle
Intro 1999-2016 25x32 = 800mm2
Production 1999-2016 12.5x32 = 400mm (2 chips/field)
Sc.2.0: 5x Magnification, 6-inch ReticleIntro 2004-2016 22x26 = 572mm2Production 2004-2016 11x26 = 286mm2 (2

Summary of Key Assumption Proposed Changes [1999 ITRS vs. Sc.2.0 Proposal] (cont.- Logic):
MPU Assumptions:
a) High Performance (HP) MPU @Ramp Starting Chip Size:
WAS: 2Mbyte on-chip (6t) SRAM in 1999
(170mm2 Core plus 280mm2 SRAM = 450mm2/1999)
IS: 1Mbyte on-chip (6t) SRAM in 1999 (170mm2 Core plus 140mm2 SRAM =
310mm2/1999)b) Cost Performance (CP) Starting Chip Size (SAME as 1999 ITRS):
MPU @Introduction/340mm2
MPU @Ramp/170mm2
c) SRAM and Logic Transistors/chip Trend (SAME as ITRS) = 2x/2yrs
d) Chip Size Growth Rate Trend
WAS/ IS: Flat chip sizes through 2001, then 1.2x/4rs
ITRS 2000 Update - Taipei, Taiwan, 11/06/00

Table 1c-j Product Generations and Chip Size Model—[Assumptions, Notes]†† MPU and ASIC Gate-length (In Resist) node targets refer to most aggressive requirements,as printed in photoresist (which was by definition also “as etched in polysilicon”, in the 1999 ITRS).
NEW: Trends have been identified, in which the MPU and ASI C “physical bottom” gatelengths may be reduced from the “as- printed” dimension. These “physical bottom” gate- lengthtargets are also included in the FEP, PI Ds, and Design TWG Tables as needs which drivedevice and process technology requirements.
§ DRAM Model—Cell Factor (design/process improvement) targets are: 1999- 2004/8x;2005- 2010/6x; 2011- 2016/4x. DRAM product generations are usually increased by 4
bits/ chip every four years with interim 2 bits/ chip generations, except: 1) at theI ntroduction phase, after the 8Gbit interim generation, the introduction rate is4x/5years (2x/2- 3yrs); and 2) at the Production phase, after the interim 32Gbitgeneration, the introduction rate is 4x/5years (2x/2- 3yrs). InTER-generation chip size
growth rate varies to maintain 1 chip per 572mm2 field at Introduction and 2 chip per
572mm2 field at Production. The more aggressive “best case opportunity” technologynode trends allow the Production- phase products to remain at 2x bits/chip every 2 years
and still fit within the target of two DRAM chips per 572mm2 field size, through the32Gbit interim generation. The InTRA-generation chip size shrink model is 0.5 everytechnology node in- between cell factor reductions.
Note: Long- Term nodes now fall on: 2010/45; 2013/33; 2016/25

Table 1c-j Product Generations and Chip Size Model—[Assumptions, Notes]
* p is processor, numerals reflect year of introduction, c is cost-performance product.
** p is processor, numerals reflect year at ramp, h is high-performance product.
† MPU Cost-performance Model—Cost-performance MPU includes small level 1 (L1) on-chipSRAM (32Kbyte/ 1999), but consists primarily of logic transistor functionality; both SRAM andLogic functionality doubles every two years.
‡ MPU High-performance Model—High-performance MPU includes large level 2 (L2) on-chipSRAM (2MByte/ 1999) added to ramp-level cost-performance core functionality shrunk from 2-year-prior generation (P99h = 11.9M transistor (Mtransistors) (shrunk P97 core) +98Mtransistors (2048 bytes 8 bits/ byte 6 transistors/ bit) L2 SRAM =110Mtransistors/ 1999); both SRAM and Logic functionality doubles every two years.
‡ MPU High-performance Model—High-performance MPU includes large level 2 (L2) on-chipSRAM (1MByte/ 1999) added to ramp-level cost-performance core functionality shrunk from 2-year-prior generation (P99h = 11.9M transistor (Mtransistors) (shrunk P97 core) +49Mtransistors (1024 bytes 8 bits/ byte 6 transistors/ bit) L2 SRAM = 61Mtransistors/ 1999);both SRAM and Logic functionality doubles every two years.
§§ MPU Chip Size Model—Both the cost-performance and high-performance MPUs InTER-generation chip size growth rates can be kept flat through 2001, due to the moreaggressive MPU/ASI C half- pitch technology node trend; but beyond 2001, the target growthrate is 1.2 growth every four years. The InTRA-generation chip size shrink model is 0.5 everytwo years through 2001, then 0.5 every three years after 2001.

++ The MPU Process/ design improvement factor is an estimate of the additional annual functional area reductionrequired beyond the area reduction contributed by the MPU metal half-pitch reduction. Note that thisadditional area reduction for transistor density plays a role generally analogous to the "cell area factor" forDRAMs. I t has been achieved historically through a combination of many factors, for example: use ofadditional interconnect levels, self-alignment techniques, and more efficient circuit layout.

Since only the 2011 odd-year product generation data column is available in the Long Term table format,interpolated numbers were calculated and included in the 2008 and 2014 node columns. The extendedmarket-need-based product trends for the product generation two-year-cycle years (1999, 2001, 2003,2005, 2007, 2009, 2011, 2013) are forecast to follow patterns established in Near Term Table 1a.
