摘要

作为绝缘栅双极晶体管(IGBT)的关键封装结构,键合线和焊接层容易因交变热应力而失效,严重改变封装结构的工作特性。本文构建了包括细键合线和焊料层结构在内的 IGBT 电-热-机多物理场耦合仿真模型,并通过实验和特性曲线验证了模型的等效性和准确性。根据所构建的健康模型,仿真结果发现位于中心位置的第四根键合线温度最高,为 38.7 °C,机械应力最大,为 55.5 MPa。随后,对单结构失效和双结构同时失效进行了研究。结果表明,键合丝失效只会对其本身的工作特性产生重大影响,而焊料层失效则会同时影响其本身和键合丝。此外,键合线失效导致的温升更为显著,增加了 86.8%,而焊料层失效导致的机械应力变化更大,增加了 178.2%。本文的研究可为提高 IGBT 的可靠性和优化 IGBT 封装结构提供指导。

Research on the multi-physical field coupling modelling of IGBT package module and the effect of different structure failure interaction
As the key package structure of insulated gate bipolar transistor (IGBT), the bond wire and solder layer are susceptible to failure due to alternating thermal stress, which can seriously change the operating characteristics of the package structure. In this paper, an electrical-thermal-mechanical multi-physical field coupling simulation model of IGBT including the fine bond wire and solder layer structure is constructed, whose equivalence and accuracy are verified by experiments and characteristic curves. Based on the constructed healthy model, the simulation results find that the fourth bond wire at the center location shows the highest temperature of 38.7 °C and the maximum mechanical stress of 55.5 MPa. Subsequently, the researches on single-structure failure and dual-structure simultaneous failure are carried out. The results show that bond wire failure only significantly affects its own operating characteristics, while solder layer failure affects itself and bond wire simultaneously. Moreover, the temperature rise due to the bond wire failure is more significant with an 86.8 % increase, while the mechanical stress change due to the solder layer failure is larger with a 178.2 % increase. The research in this paper can guide the reliability improvement of IGBT and the optimization of IGBT package structure.

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.
