Abstract

This work offers a comprehensive study on temperature determination and development of IGBTs via temperature-sensitive parameters (TSEPs) during repetitive switching events. The obtained information is discussed and judged with respect to accuracy for different device technologies. This evaluation is extended by the aspect of artificial front-side aging for different emitter-pad designs. For two different designs investigated, no decreased switching robustness could be verified, even beyond the AQG 324 [1] lifetime border, which is defined by a certain forward voltage drop increase.

IGBT发射极衬垫设计和前端老化对开关稳定性和温度分布的影响

这项工作提供了在重复开关事件中通过温度敏感参数（tsps）确定温度和开发igbt的全面研究。针对不同的器件技术，讨论并判断所获得的信息的准确性。通过对不同发射垫设计的人工前端老化方面对该评价进行了扩展。对于所研究的两种不同的设计，即使超过AQG 324[1]寿命边界（由一定的正向压降增加定义），也没有证实开关鲁棒性下降。

期刊介绍： Microelectronics Reliability, is dedicated to disseminating the latest research results and related information on the reliability of microelectronic devices, circuits and systems, from materials, process and manufacturing, to design, testing and operation. The coverage of the journal includes the following topics: measurement, understanding and analysis; evaluation and prediction; modelling and simulation; methodologies and mitigation. Papers which combine reliability with other important areas of microelectronics engineering, such as design, fabrication, integration, testing, and field operation will also be welcome, and practical papers reporting case studies in the field and specific application domains are particularly encouraged. Most accepted papers will be published as Research Papers, describing significant advances and completed work. Papers reviewing important developing topics of general interest may be accepted for publication as Review Papers. Urgent communications of a more preliminary nature and short reports on completed practical work of current interest may be considered for publication as Research Notes. All contributions are subject to peer review by leading experts in the field.
