1. Upcoming Courses
Special Event at Semicon West!
Reliability and Characterization Challenges for Advanced Semiconductor Devices
Dr. John Suehle and Dr. Jeffrey Gambino
Friday, July 14 (8:30 AM - 5:00 PM) in San Francisco, Moscone Center North Hall
Semitracks, along with Semiconductor International, have put together a one-day course on the Reliability and Characterization Challenges for Advanced Semiconductor Devices. Dr. John Suehle of the National Institute of Standards and Technology and Dr. Jeffrey Gambino of IBM, two leading researchers and lecturers in field of Semiconductor Reliability, will give an overview of the problems and reliability challenges associated with today's advanced semiconductor devices.
Dr. Suehle will cover front-end reliability issues including: Hi-K dielectrics, Negative Bias Temperature Instability, and Positive Bias Temperature Instability. Dr. Gambino will cover back-end process integration and reliability issues including: copper metallization, electromigration, stress induced voiding, and Lo-K dielectric breakdown. The course will be held in San Francisco on Friday, July 14 from 8:30 AM to 5 PM with an hour and a half lunch break. To learn more about this course, visit the course page here.

3. Course Schedule
Invest in yourself and your staff. Time is running short to enroll in our Summer courses on Packing Technology, Packaging Design, Process Integration, Reliability, and Failure and Yield Analysis. Come and learn from the experts!
Packaging Technology and Challenges
Semitracks, Inc. and Semiconductor International have put together a course which will provide an overview of the current business climate, anticipated trends and the associated impact on assembly/packaging roadmaps. There will be an in depth discussion of both high-end CPU roadmaps plus the roadmaps to address the multitude of communications and network devices that are driving the digital revolution.
- (September 11-12, 2006) - Dallas, Texas
Semiconductor Process Integration
Semitracks, along with Semiconductor International, have put together a three-day course on Semiconductor Process Integration for CMOS, Analog, and Mixed Signal Technologies. Dr. Badih El-Kareh of Texas Instruments will give an overview of the process integration challenges associated with today's advanced semiconductor devices. Dr. El-Kareh will cover passive and active components, contact and interconnect issues, isolation technologies such as STI and SOI, transistor integration issues, as well as full CMOS, BiCMOS and high speed bipolar process integration techniques.
- (September 11-13, 2006) - Dallas, Texas
Packaging Design and Modeling
Semitracks, Inc. and Semiconductor International have assembled a course on IC Packaging Design and Modeling. This course provides an overview of the packaging design process. The course covers current packaging technologies, including chip scale packaging, Ball Grid Array technology and other current concepts. This class focuses on techniques and the importance of thermal and mechanical simulations. Discussions and examples will concentrate on thermal performance simulations, assembly & packaging stresses, package reliability (including solder joint fatigue simulation), and interactions between chip and package. In addition, a special section will be examples of successful wafer level simulations.
- (September 13-15, 2006) - Dallas, Texas
Failure and Yield Analysis Course
Failure and Yield Analysis is an increasingly difficult and complex process; engineers are required to locate defects on complex integrated circuits. In many ways, this is akin to locating a needle in a haystack, where the needles get smaller and the haystack gets bigger every year. Engineers are required to understand a variety of disciplines in order to effectively perform failure analysis. This requires knowledge of subjects like: design, testing, technology, processing, materials science, chemistry, and even optics! Failed devices and low yields can lead to customer returns and idle manufacturing lines that can cost a company millions of dollars a day. Your industry needs competent analysts to help solve these problems. This is a multi-day course that offers detailed instruction on a variety of effective tools, as well as the overall process flow for locating and characterizing the defect responsible for the failure.
- (September 18-21, 2006) - Boston, Massachusetts
Semiconductor reliability is at a crossroads. In the past, reliability meant discovering, characterizing and modeling failure mechanisms and determining their impact on the reliability of the circuit. Today, reliability can involve tradeoffs between performance and reliability, assessing the impact of new materials, dealing with limited margins, etc. Analysis and experimentation is now performed at the wafer level instead of the packaging level. This requires knowledge of subjects like: design of experiments, testing, technology, processing, materials science, chemistry, and customer expectations. While reliability levels are at an all-time high level in the industry, rapid changes may quickly cause reliability to deteriorate. Your industry needs competent engineers and scientists to help solve these problems.

5. Technical Tidbit
Velocity saturation is a major limitation for today’s advanced semiconductor devices. This graph shows the relationship between the carrier drift velocity for electrons and holes as a function of the electric field. As the field is increased, the carrier velocity saturates at Vsat. In this condition, the carriers lose all of the energy that they gain from the collisions to the crystal lattice. The average carrier velocity does not increase, but the number of carriers at the saturation velocity does. The field dependent carrier mobility can be approximated by the equation shown here, where ueff is the effective mobility, u0 is the low-field mobility, E is the electric field, and beta is 2 for electrons, and 1 for holes. This yields a saturation velocity of around 1×107 cm/sec for holes, and around 8.5×106 for electrons.
