1. Special Event at Semicon West - Time is Running Out!

Dr. John Suehle and Dr. Ennis Ogawa - Reliability and Characterization Challenges for Advanced Semiconductor Devices

Monday, July 11 (9:00 AM - 5:00 PM) at The City Club of San Francisco

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. Ennis Ogawa of Texas Instruments, 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. Ogawa will cover back-end reliability issues including: copper metallization, electromigration, stress induced voiding, and Lo-K dielectric breakdown. The course will be held at the City Club San Francisco on Monday, July 11 from 9 AM to 5 PM with an hour and a half lunch break. To register for this unique event, click here.

2. Upcoming Conferences

Semicon West

July 12-14, 2005 Moscone Center, San Francisco, CA

We will be located in West Hall, Level 2, Booth #8719 (diagonally opposite Panasonic Factory Automation). We are part of the Final Manufacturing portion of the show.

International Symposium for Testing and Failure Analysis

November 6-10,2005 San Jose Convention Center in San Jose, CA

3. Course Schedule

Invest in yourself and your staff. Time is running short to enroll in our Spring courses on Semiconductor Reliability, Failure and Yield Analysis, FIB Technology, and Packaging. Come and learn from the experts!

Process Integration

Process Integration is becoming more challenging with each technology node. The fortunes of your company may depend on how successfully you and your team can integrate disparate processing steps into a single, optimized flow. Lily Springer, our expert in Process Integration and Mixed Signal Design, guides you through the critical and challenging aspects of this topic. She covers both digital and analog issues related to process integration. Let your colleagues know!!

Semiconductor Process Integration (August 10-12) – San Diego, California

Failure and Yield Analysis

Are you new to failure analysis? Does your position require you to have an understanding of failure analysis? Learn about the latest techniques for analyzing complex devices. We cover all the techniques from the simple ones (such as Liquid Crystal) all the way to complex ones (such as PICA and Laser Voltage Probing). Learn the secrets of analyzing a component right every time.

Failure and Yield Analysis (September 12-15) – Singapore

Failure and Yield Analysis (September 19-22) – Santa Clara, California

Reliability

Reliability is a critical element to the success of any semiconductor product. Reliability margins are increasingly squeezed by today’s deep submicron technologies. Learn about the major reliability failure mechanisms, test structures, and test equipment. Learn how to optimize reliability, performance, and cost.

Semiconductor Reliability (September 26-28) – Santa Clara, California

4. Semitracks Segment of the Month

Semitracks’ new and improved online training is convenient, up-to-date, and cost effective. Access the same material presented in our courses whenever you need it, right when you need it without having to worry about the high costs and hassle of traveling. The semiconductor field is an ever-changing one. With access to the most current information, you can stay on top of the new technology. Online training is also very cost effective. For only $500 per year, you gain access to thousands of dollars worth of courses and course material.

Give our online training a try – for free. This month’s topic is Ionic Contamination.

Ionic contamination, although not considered to be a big factor in today's semiconductor processing, can still be a serious reliability issue.

This segment is no longer available. If this topic interests you, perhaps you would be interested in our Online Training. For more information or to sign up, click here.

5. Technical Tidbits

Mobile Ionic Contamination

This diagram shows how mobile ions behave under the influence of an electric field. On the left, we have an MOS structure with no applied field. Under these conditions, the mobile ions are randomly distributed throughout the oxide. Once an electric field is applied, the ions begin to move. The diagram on the right shows how ions move within the MOS structure under the influence of an electric field. Notice that the mobile ions move toward the interface between the silicon and silicon dioxide under the influence of a positive voltage applied to the gate. The proximity of the positive ions to the silicon-silicon dioxide interface creates a mirror image charge in the silicon immediately across the interface. This directly affects the threshold voltage. If a negative voltage is applied to the gate, the ions would move toward the gate and away from the silicon. Positive ions are more of a concern than negative mobile ions, since they are smaller and can move more freely throughout the oxides.
