IP Session 2C: DEVICE DEGRADATION AND
INFANT MORTALITY
Organizers: J. W. Tschanz – Intel
Moderator: G. Eide – Magma
Description: In an era of increasing performance targets and ever more stringent power requirements, design margins are shrinking more than ever. It is therefore critical to be able to understand the factors which impact product reliability and to accurately predict their effects. Overestimate the impact of NBTI, HCI, and TDDB on the product, and critical performance or power is left on the table. Underestimate these effects and the product suffers an unacceptable failure rate. Further complicating this picture is the fact that the relative importance of these different degradation mechanisms can change drastically from one process generation to the next.
The three presentations in this session show how a combination of careful modeling combined with product measurement data is used to set the reliability guardbands that are used. The speakers will demonstrate their unique approaches towards reliability modeling and characterization, and give insight into the reliability testing and characterization challenges that lie ahead.

ROBUST DESIGN: TECHNIQUES AND
TRENDS
Organizer: M. Zhang – Intel
Moderator: Z. Navabi – Worcester Poly
Description: Relentless technology scaling presents a challenging task of designing reliable systems in the presence of transient, intermittent, and gradual errors. It is crucial for the design & test community to understand the origin and impact of these errors, methods to characterize, screen, and analyze them, as well as design techniques to mitigate them. In this session, the speakers will provide comprehensive reviews of these three aspects of the robust design challenges with different industry/academia perspectives. Discussion on error sources will focus on soft errors, process variation, and device degradation. Both theoretical modeling of these effects and experimental data from test chips will be presented. We will focus on logic and memory circuits for the design techniques to demonstrate the principles of robust design. A full-chip deployment strategy of such robust circuit elements will also be discussed. Experimental data and theoretical projection on sub-65nm technologies will be presented to illustrate the trend and potential new challenges for future technologies and motivate future robust design research.

IP Session 6C: POST-SILICON VALIDATION:
CURRENT PRACTICES AND NEW
CHALLENGES
Organizer: S. Gupta – Univ. of South. Cal.
Moderator: M. Hunt – Qualcomm
Description: In most existing flows for custom or semi-custom design, the quality of chips shipped to customers is ensured via a sequence of three processes, namely pre-silicon verification of a chip’s design, post-silicon validation of the first-silicon for the design (i.e., the first set of chips fabricated for the design), and testing of each fabricated copy when the design is fabricated in high volume. While verification and testing have been active areas of research, post-silicon validation has developed primarily via intensive engineering practice. However, a noticeable trend has emerged in recent years: Despite advances in design and verification, for high-performance designs it is becoming increasingly common for many causes of circuit misbehavior that can cause significant yield loss to be first discovered during post-silicon validation. This presents numerous challenges, many of interest to the testing community. In this session, validation experts from three leading companies will share their insights. First, they will describe their validation methodologies and some recent case studies. Second, they will present emerging challenges, especially those the testing community may be able to address, e.g., development of new approaches to estimate and enhance quality of validation and new techniques to identify root causes behind erroneous behaviors exposed during validation.

IP Session 7C: DESIGN FOR YIELD AND
MANUFACTURABILITY
Organizer: S. Shoukourian – Virage Logic
Moderator: S. Taneja – Cadence
Description: Increased manufacturing variability in leading-edge process technologies requires new paradigms and solution technologies for yield optimization. SoC manufacturability and yield entails design-specific optimization of the manufacturing, and thus enhanced communications across the design-manufacturing interface. A wide range of Design-for-Manufacturability (DFM) and Design-for-Yield (DFY) methodologies and tools have been proposed in recent years. Some of these tools are leveraged during back-end design, others are applied post-GDSII, and still others are applied post-design, from reticle enhancement and lithography through wafer sort, packaging, final test and failure analysis. DFY and DFM can dramatically impact the business performance of chip manufacturers. It can also significantly affect age-old chip design flows. Using DFY and DFM solutions is an investment, and choosing the most cost effective one(s) requires careful analysis of integration and schedule overheads, versus quantified benefits. This session analyzes the key trend and challenges, and provides a set of innovative DFM and DFY practices used for today’s SoC designs.

YIELD MANAGEMENT & DPPM REDUCTION
Organizers:
P. Ehlig, A. Kokrady – Texas Instruments
Moderator: T. M. Mak – Intel
Description: With shrinking technology, it is getting harder to manufacture and test memories which today occupy more than 50%-60% of chip area and dominate the defects and customer returns in today’s integrated circuits. Previously unheard of fault/defect types are causing designs to fail reducing yield and increasing Defective Parts per Million (DPPM). It is important for the design & test community to understand the need to screen and analyze the defects and find out techniques to mitigate them. In this session, we explore various ways of reducing the impact on yield and DPPM.

NANOELECTRONICS – WHAT NEXT? FROM
MOORE’S LAW TO FEYNMAN’S VISION
Organizers:
S. Mourad – Santa Clara Univ.,
Y. Zorian – Virage Logic
Moderator: S. Mourad – Santa Clara Univ.
Description: The limit of present silicon transistors is set by the manufacturing process and not by the laws of physics. Emerging nanomaterials has provided new possibilities for higher packing density, higher carrier mobilities, and higher/lower dielectric constants. Although nanotechnology is usually defined as utilizing technology with less than 100nm in the minimum feature size, nanoelectronics often refer to devices that are so small that inter-atomic interaction, ballistic transport, and quantum mechanical properties need to be studied. These phenomena are expected to assume much more prominent roles in silicon-based devices fabricated using sub-45 nm technologies.
Nanoelectronic devices such as Single Electron Transistor, Resonant Tunnel Diodes and Quantum Dot Arrays are still under development as practical circuitry, but they do hold a great promise. This is also true of molecular devices that can self-assemble to form a large system. One of the best known families of nanomaterials is carbon nanostructures such as nanotube, nanofiber, and graphene. They hold great promise as candidates for ultra-fast switches as well as interconnect and thermal interface materials. In this session, three speakers will present different facets of nanoelectronics to prepare us test engineers for the challenges integrated circuit technology faces now and in the near future.

Description: This session is the final round of the TTTC 2008 Best Doctoral Thesis Contest. This contest is organized by the TTTC Student Activities Committee for the fourth consecutive year and aims to promote and strengthen the interaction between graduate students and the industrial community, as well as to serve as a process by which student work is exposed to and tested under real-life industrial needs. This is achieved by offering students the chance to present their work in a conference environment to academic and industrial test experts, who will evaluate and comment in terms of novelty and advancement of industrial practice.
In the preliminary round of this contest, doctoral students who are expected to graduate in 2008 were invited to submit a one page abstract of their thesis, where they defined the problem and its relevance to industry, described existing industrial practices for solving the problem and explained the proposed methodology and how it advances the theory and/or practice in the particular field. The abstracts were reviewed by a panel of industrial and academic experts and a set of finalists were selected for the final round of the contest.
In this final round, during a dedicated session at the IEEE VLSI Test Symposium (VTS’08), each contestant is given a ten minute slot in front of a panel of experts, split equally between oral presentation and Q&A period. The panel of experts will judge the presented doctoral theses with regards to theoretical advancement, industrial relevance and presentation, and the winner of the contest will receive the 2008 TTTC Doctoral Thesis Award during the social event of the Symposium, to which all finalists are invited. The award consists of a certificate, an honorarium and an invitation to submit a paper on the presented work to the IEEE Design & Test magazine.

IP Session 10C: TESTING FOR COMPLEX
FAILURE MECHANISMS AND PROCESS
VARIATIONS OF MEMORIES
Organizers: M. Azimane – NXP
Moderator: B. Wang – AMD
Description: Memory area on current designs in the 90nm, 65nm and 45nm designs is increasing exponentially given the nature of applications and the drive to embed entire systems on a single chip. With ever increasing process complexity and shrinking technologies, different defect types that manifest themselves as complex failure mechanisms and process variations on memories are also increasing proportionally. Traditional memory test techniques like functional vectors are no longer sufficient. In the mean time, new DFT methods and Built-in Self-Test (BIST) approaches are evolving to test for these defects and garner enough data to increase memory test efficiency.
In the first presentation, Azimane et al. from NXP Semiconductors will focus on additional DFTs that could be implemented in addition to BIST test algorithms to catch complex failure mechanisms and worst case process variations. They show that the fault coverage of conventional march tests have reached saturation phase and time has come to jump to new test methods.
In the second presentation, and in cooperation between LIRMM and Infineon, Dilillo et al. have analyzed the impact of technology scaling on defects and parameter deviations in embedded SRAMs. They showed how the impact of manufacturing defects may vary with the level of integration (130 nm down to 45 nm) of eSRAMs core-cell belonging to the same family. Secondly, they illustrate the effects of technology scaling (130 nm down to 45 nm) on device parameter variations.
In the third presentation, Jayaram et al. from Texas Instrument will address the pros/cons of BIST techniques and show how programmable BIST offers almost unlimited flexibility on screening known and unknown defects in the presence of process variation. In addition, they will offer some case-studies on hard-to-screen defects and present some implementation-level details of programmable BIST on today’s complex designs. They will also address the aspect of designing memories to make test easier and highlight some features that are critical in enabling efficient debug. Finally, they will cover some aspects of hard vs. soft repair and external vs. Built-in Self-Repair (BISR).

EMBEDDED TUTORIAL:
A SURVEY OF ON-CHIP DELAY
MEASUREMENT TECHNIQUES FOR
PRODUCTION TEST – FROM NANO TO
PICOSECONDS
Organizer & Presenter: S. Sunter – LogicVision
Abstract: As CMOS IC dimensions scale below 90 nm, delays-of-interest range from nanoseconds to picoseconds. This increases the need for greater time measurement accuracy but off-chip (ATE-based) delay measurement techniques are becoming severely limited by fundamental properties of signal access paths off-chip and on-chip, such as noise, wire length, and impedance variation. On-chip measurement techniques have been proposed by IC designers, DFT engineers, and test engineers, with claimed accuracies ranging from nanoseconds to femtoseconds, at least in simulation.
This tutorial will survey most of the papers that provide silicon results published in the last 10 years, in both design and test journals/conferences, and some representative papers that include only simulated results, to discover the most promising directions for measuring and production testing today’s and future delays-of-interest. Delay parameters include instantaneous delay, average delay, and delay variation (long and short term, including jitter) in digital, analog, and wire paths, and they typically depend on voltage, frequency, and conditions. The measurement techniques will be categorized by suitability for measurement of one-shot and periodic events, then by measurement principle, and lastly by circuit technique and reported real-silicon capabilities.
The goal is to identify principles and techniques suitable for production testing (quick and process tolerant, using insignificant silicon area) and for IC characterization and debug too (flexible to handle unanticipated delays and accuracy).
Some of the conclusions are: isolation between engineers in different disciplines (design, DFT, test) results in sub-optimal solutions; simulations can be enhanced to include many deleterious effect but real silicon provides surprises when it comes to picoseconds; progress in the last 10 years has not tracked technology scaling because of discipline isolation and emphasis on simulation; a new standard test pin type might accelerate progress towards meeting production test requirements.
The intended audience is DFT and test engineers, and researchers.

MITIGATING RELIABILITY, YIELD AND
POWER ISSUES IN NANO-CMOS: DESIGN
PROBLEM OR EDA PROBLEM?
Organizer: M. Nicolaidis – TIMA
Moderator: Y. Zorian – Virage Logic
Co-Organized with: IEEE Design & Test of Computers
Description: Silicon based CMOS technologies are fast approaching their manufacturability limits. In newer processes, power dissipation, fabrication yield, and reliability are steadily worsening, making further nanometric scaling increasingly difficult. In particular, yield as well as reliability are threatened by issues such as manufacturing process variations, on-chip voltage and temperature variability, accelerated aging and wearout, radiation induced soft-errors and cross talk.

Session 13C: SPECIAL SESSION
PANEL:
IS UBIQUITOUS RF AT ODDS WITH TEST?
Organizers: A. Khoche – Verigy
Moderator: A. Chatterjee – Georgia Inst. of Tech.
Description: The drive for using RF to provide universal connectivity is forcing various wireless standards being supported in a single device. Moreover this functionality is expected in consumer devices where the cost pressure is significant. The cost pressure coupled with the everlasting quest for miniaturization leads to many of these wireless interfaces being added to a single chip or a package. The instrumentation required for testing an RF interface is traditionally more expensive than the digital, memory or mixed signal components. The proliferation of RF interfaces on a chip/package would push the test cost even higher and could potentially become a bottleneck in enabling such ubiquitous RF devices. This panel will discuss state of RF test technology with respect to the needs of such ubiquitous RF devices to identify the gaps, if any.
