  8. 2007 Wireless Requirement Tables • CMOS • Performance Analog CMOS • Continue linkage to Low Standby Power (LSTP) CMOS roadmap with 1 year lag (Supply Voltage, Tox, Gate length ) • RF & AMS parameters including: Ft/Fmax. Noise Fig, Gm/Gds, 1/f noise and Vt matching • Precision Analog CMOS • Thick gate oxide CMOS • No update for 2007 • New 2007, CMOS requirements for mm-Wave • Link to High Performance CMOS roadmap with 2 year lag • Added RF parameters: Ft/Fmax. Noise Fig @ 24GHz & 60GHz 2007 ITRS DRAFT DO NOT PUBLISH

  9. 2007 Wireless Requirement Tables • Bipolar • 3 Separate Bipolar devices: • High Voltage – “typical” low-cost bipolar device • High Speed – mm-Wave applications • PA – power amplifier applications • Focus on high speed and PA bipolar as drivers • 2007 reduce high speed device Ft scaling (delay 300 GHz by 1 yr and 500 GHz by 5 yrs). Adjust Fmax, JC and BVCEO scaling accordingly. • Revised PA NPN parameters, aligned to PA battery voltage • Noise Figure @ 60 GHz • On-Chip Passives • 3 applications: Analog, RF and Power Amplifier • Devices include: Capacitors, Resistors, Inductors, Varactors • 2007 add MOM RF capacitor 2007 ITRS DRAFT DO NOT PUBLISH

  10. 2007 Wireless Requirement Tables • Power Amplifier • Handset : HBT & FET, III-V and Si • 2007 add end-of-life battery voltage, FET/HBT integration for integrated bias circuit design, on-chip switch integration (for stage by-passing). • Emerging markets driving PA to a cost/performance driven and a cost only driven applications. Cost-only market driving silicon single chip alternatives. • Base Station: Cellular and emerging WiMAX • Required relatively high RF power, LDMOS & III-V FET • 2007 drop SiC device, displaced by GaN device • mm-Wave • Dominated by III-V (GaAs PHEMT, InP HEMT, GaAs MHEMT, GaN HEMT, InP HBT ), plus SiGe HBT and RF CMOS (2007) • Low noise amplifier and power devices 2007 ITRS DRAFT DO NOT PUBLISH

  11. MtM Focus of Wireless Multi-Standard Applications • Address multi-band, multi-mode, portable applications • Present device roadmap alone does not enable software defined radio (SDR); needs to: • Address digital radio design requirements • Address Hybrid approach with wideband amplified and matching, filtering and switching network • module assembly and embedded passives requirements (new table) • RFMEMS requirements (new table) 2007 ITRS DRAFT DO NOT PUBLISH

  12. Embeded Passives Table • Consider 3 elements on various module substrates such as organic and low-temperature co-fired ceramic (LTCC): • Resistor • Capacitor • Inductor • Requirements for example in: • Tolerance • Temperature linearity • Resonance frequency • Sheet resistance • Breakdown voltage 2007 ITRS DRAFT DO NOT PUBLISH

  13. RF MEMS Table • Focus on 4 elements: • BAW • Resonator • Switch capacitive contact • Switch metal contact • Requirements in: • Design tool • Packaging • Performance driver • Cost driver 2007 ITRS DRAFT DO NOT PUBLISH

  14. Wireless Working Group Key Considerations • Traditional Roadmap Drivers: • Cost (scaling, die size, part count) • Power Consumption • Chip Functionality • Non-traditional Roadmap Drivers: • Government regulations determining system spectrum and specifications • Standards and protocols drive frequencies, power and performance • Color coding “Manufacturing solutions exist” does not imply product volume shipment per ITRS definition • RF module form factor (size and height requirements) • Cost / Performance Drives Integration: • Multi-band Multi-mode system applications (embedded passives, filter, switch integration) • Signal isolation and integrity • Analog Shrink (power supply, area, design innovations) 2007 ITRS DRAFT DO NOT PUBLISH

  15. Challenges and Trends • Radio Integration: • Performance and cost trade off for SoC vs SiP solution • Signal isolation - challenge to technologists, designers, and EDA tool providers • CAD solution for Integrated Radio SiP design (chip, passive, MEMS, package, tool compatibility, model accuracies) • Device Technology: • Optimizing analog/RF CMOS devices with scaled technologies. Fundamental changes in CMOS device structure may lead to the need of separate process/chip to support conventional precision analog/RF devices • Cost and performance tradeoff of integrating passive devices • Predictability of battery technology (end-of-life) and its impact on PA roadmap • Compound semiconductor substrate quality, reliability, thermal management • Design: • Design approach for wider range of supply voltages • Digitizing analog functions, Software Define Radio (SDR) 2007 ITRS DRAFT DO NOT PUBLISH
