what is the itrs
What is the ITRS?
  • The International Technology Roadmap for Semiconductors (ITRS) is an assessment of semiconductor technology requirements.
  • The objective of the ITRS is to ensure advancements in the performance of integrated circuits.
  • This assessment, called roadmapping, is a cooperative effort of global industry manufacturers and suppliers, government organizations, consortia, and universities.
  • The ITRS identifies the technological challenges and needs facing the semiconductor industry over the next 15 years.
  • It is sponsored by the European Semiconductor Industry Association (ESIA), the Japan Electronics and Information Technology Industries Association (JEITA), the Korean Semiconductor Industry Association (KSIA), the Semiconductor Industry Association (SIA), and Taiwan Semiconductor Industry Association (TSIA).
  • SEMATECH is the global communication center for this activity. The ITRS team at SEMATECH also coordinates the USA region events.

itrs technology working groups
ITRS Technology Working Groups
  • The ITRS process encourages discussion and debate throughout the community about the requirements for success.
  • The key factor in the success of the Roadmap is obtaining consensus on industry drivers, requirements, and technology timelines.
  • The Technology Working Groups are the organizations that "build" the roadmaps.
  • These representatives assess the state of technology and identify areas that may provide solutions.
  • The TWG members also indicate opportunities for new research and innovation.
  • These groups are made up of volunteer technology experts from chip manufactures, supplier companies, universities and academia, technology labs, and semiconductor technology consortia.
  • The Technology Working Groups, also known as TWGs, are comprised of the technical disciplines of
    • System Drivers

  • ITRS/iNEMI are working together to align their Semiconductor Assembly & Packaging Roadmaps.
    • Many of the same people are on both teams.
    • Some IMAPS members are also on both teams.
  • IMAPS’ focus is on Semiconductor Assembly & Packaging.
  • It’s a natural fit to take the output of the ITRS/iNEMI Semiconductor Assembly & Packaging Roadmaps and use that output to direct IMAPS’ activities towards solving gaps in the roadmap.
  • IMAPS’ corporate members will benefit by developing real industry solutions for real industry challenges.

ITRS: Single Chip Package
  • Incremental improvements in traditional assembly technologies will not be sufficient to meet market requirements.
  • The substrate dominates the cost of single chip packaging.
  • Cost per pin has been trending up, instead of down.
  • Operating temperatures are a problem in harsh environments.
  • Higher frequency chip-to-board speeds for peripheral buses.
itrs high pin count packages
ITRS: High Pin-Count Packages
  • Package pin count grows as higher frequency and higher power density demand more power and ground pins.
  • Substrate technology requires micro-vias, blind & buried vias, stacked vias and tighter lines and spacing.
  • Substrate technology advances lead to significant cost increases for design/test and a reduced supplier base.
  • System-in-Package will become more important to reduce the need for high density interconnects in the package substrate and the PCB.
itrs chip to package substrate

    • A BGA based SiP may house optical connectors, laser diodes, photodetectors, CMOS IC containing receivers/drivers and multiplexer/demultiplexer, plus RF connectors, and decoupling capacitors.
itrs rf packaging
ITRS: RF Packaging
  • Many of the technology challenges for RF packaging arise from the fact that the IC packaging engineering practice, technology knowledge base, and manufacturing infrastructures have been based upon digital IC packaging developed in the last forty odd years.
  • Issues
    • The inductance characteristics associated with bonding wires and leaded packages, and effect of molding compound materials limit the RF performance.
    • RF package modeling tools and materials properties database for package design and device-package co-design for the broad spectrum of RF market applications.
    • Improvements in materials properties—molding compounds, underfills, substrates are required.
    • Being able to embed passive components in LTCC.
    • To meet the low cost challenges, embedded inductance and capacitance components and networks in organic packaging for RF applications must be diligently pursued.
    • Tools to enable device package co-design in SIP packages will be very important.

    • Major concerns are patient safety and risk mitigation.
    • For life-sustaining devices, component failure rate as low as 100 ppm, few ppm critical failure rate.
    • Challenge to capture low occurrence failures in reliability testing.
    • EMI is a major concern.
    • Pressure requirements: in a barometric pressure chamber or while scuba diving.
    • Defibrillation devices could generate significant localized heating in the high voltage charging circuit when delivering therapy, challenging the package substrate and PCB.
    • In accordance with regulatory requirements for medical devices
    • Requirements for control of the manufacturing environment, labeling of the packages, and documentation.
itrs cost
ITRS: Cost
  • Today packaging costs often exceed die fabrication costs.
  • Leadfree solders.
  • Low K & High K dielectrics.
  • Higher processing temperatures.
  • Wider range of environmental temperatures.
  • More efficient thermal management needed.
itrs reliability simulation
ITRS: Reliability & Simulation

New failure modes caused by new materials needed to meet environmental and performance requirements, result in significant challenges in field reliability prediction based on accelerated lab testing for broad product application field requirements.

  • The introduction of the new materials and structures to meet environmental, heat and speed requirements are posing new reliability challenges.
  • New technology will be required to meet the reliability goals including:
    • New reliability tests such as drop tests for mobile products.
    • Correlation between field- and laboratory testing.
    • Improved methods for failure detection and analysis (e.g., X-ray, acoustic, nano-deformation and localized residual stress measurement.)
    • Materials and interface characterization. Interfacial delamination will continue to be a critical reliability hazard that is worsened by the trends to larger chips, new materials and increased layer count. More layers require the understanding of more interfaces.
    • Simulation and modeling for life time prediction (e.g., multi-field coupling, structure-property correlation, ab-initio methods, modular and parametric approaches).
