We will be located in Booth #315.
3. Course Schedule
Invest in yourself and your staff. Time is running short to enroll in our Fall courses on Semiconductor Reliability, Failure and Yield Analysis, and Process Integration. Come and learn from the experts!
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 (December 5-7) – Santa Clara, 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 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
We offer other courses as well as in-house courses. For more information, visit our website at http://www.semitracks.com.
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 Time Resolved Emission.
Time resolved emission is emerging as the best technique for obtaining waveform information from advanced integrated circuits during debug and failure analysis.
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
The resistivity of silicon plays an important role in power semiconductor devices. This graph plots n-type silicon resistivity as a function of temperature for several different doping concentrations. Notice that as the doping concentration increases, the resistivity decreases. Also notice that for lower doping concentrations, the resistivity initially increases with temperature, but then decreases as the temperature goes higher. The higher temperature regimes can lead to a negative thermal feedback condition. As the temperature gets hotter, the resistance drops, allowing even more current to flow. This situation can lead to current crowding, and eventually melting of the silicon. This is a concern because a low doping concentration is required to stand off high voltages. Therefore, it is important to design the silicon device and its packaging such that this does not occur. In order to keep a power semiconductor device from operating in this region, one must design the heat sink such that the thermal energy is pulled away, preventing the device from reaching the negative thermal feedback regime.
