    The DFT Tester Table debuted in the 1999 edition

    The 2000 update represents the trends that were described
     in the 1999 edition
    Significant changes are intended to clarify the requirements
     based on the significant industry confusion evident in 2000
    This table will receive significant focus for the 2001 edition

 Commodity Flash Table
    In 2000 minor adjustments were made to the trends that
     were described in the 1999 edition
    Requirements for a scan vector capability were added to
     address a growing trend towards integration of logic on flash
     devices

            Industry Trend - Cost
 Manufacturing cost continues to be the
   dominant factor in test
       Test represents an increasing percentage of
        overall device manufacturing cost
       1999 edition cost targets begin to trend cost in the
        right direction

       Increasing levels of design integration drive new
        test challenges
       Integration of logic, analog, RF, RAM, ROM,
        and/or Flash on a single chip is on the horizon
       How to test highly integrated components at a cost
        consistent with the market for these devices?

        Industry Trend - Wireless
 Dramatic growth in the consumer wireless
   market segment over the foreseeable future
   requires cost effective solutions for RF testing




       2.4GHz and 5.2GHz bands are targeted for a
        large number of products in many applications
        (Bluetooth, 802.11x, …)

            Industry Trend - HSS
 High speed serial (HSS) technologies are not
   just for long range communication anymore
       Serial communication is becoming the technology
        of choice for peripheral connectivity
       Slow parallel bus architectures are being replaced
        by Firewire, Infiniband, and other HSS solutions
       Traditional rack and stack approach to test of high
        speed ports is too expensive

         Industry Trend - Power
 Once an afterthought, precise power delivery
   is crucial for high performance designs
       Voltage droop during test has
        a direct impact on
                                                DUT Current Load Step
        manufacturing yield               IDD
       High current power delivery
                                          0A
        requires accurate modeling
                                                Voltage as Seen by DUT
        and simulation of the entire
                                         VCC
        power path
       High precision analog circuits
        require very stable
        references                       Time

     Industry Trend - Diagnosis
 Validation and debug of complex designs require an
   increased level of interactivity between design
   automation and test equipment
       Correlation must be established between a device failure
        and the actual failing circuit node
       Automation tools are needed to shorten the process of
        tracing failures to the failing circuit as a direct impact to time
        to market
 Emerging packaging technologies compromise
   existing failure analysis techniques
       Flip-chip and multi-chip packaging require new approaches
        to probing for diagnosis and failure analysis

               Industry Challenge
 The ATE business model must change to
   adapt to evolving market directions
       The high performance functional tester market
        segment is declining
       Low performance functional tester and DFT tester
        market segments are growing
       The industry must come together to define
        common requirements for DFT tester capability




December 6, 2000                                       11
Manufacturing Cost Initiatives
 Technologies are emerging to lower equipment
   capital cost and increase test module throughput
       The industry is driving toward DFT technology to move test
        complexity onto the die and away from the test equipment
       Reduction in test equipment complexity should result in a
        significant decrease in tester cost over the 5 year horizon

       DFT will be used to enable lower performance functional
        testers to test high performance designs

       DFT techniques that reduce device pin count requirements
        for test enable increased parallelism and module throughput
       Wafer level burn-in and test exploits high parallelism to
        increase throughput and decrease unit cost

                   System-on-a-Chip
 Solutions must emerge to solve Big D / Big A
   test challenges
       Today’s environment is structured for Little D / Big
        A or Big D / Little A

       SoC testing requires a disciplined DFT approach
          Fundamental research is needed to define and prove
           Analog BIST and DFT techniques
          Extensive digital DFT techniques must be applied

          Embedded flash and PROM test time threatens test
           module throughput
       Test cost is a primary concern

                   High Speed Serial
 High performance digital interfaces are
   approaching the analog domain for testability
       High speed serial digital interfaces must be
        characterized and tested in the analog domain
       Analog compliance
        testing is time
        consuming
       Trade-off between
        increased tester
        resources, test time,
        and test effectiveness
