我们在研究中发现,在三极管管芯铝电极上涂敷一层聚酰亚胺树脂,对提高铝电极的抗电迁移能力是明显的,而且对提高三极管的电性能稳定性也很有好处.聚酰亚胺是一种性能优越的热塑料树脂,约在:-310～340℃的温度范围内可保持良好的机械性能和电性能,而且具有耐辐射、耐氧化等优良性能.其抗拉伸强度及热变形温度都很高.铝电极表面可以看成是一个连续的晶粒边
In our study, we found that coating a polyimide resin on the triode die-attach aluminum electrode is significant to improve the anti-electromigration ability of the aluminum electrode and is also beneficial to improve the electrical stability of the triode. Polyimide is a superior performance of thermoplastic resin, about: -310 ~ 340 ℃ in the temperature range to maintain good mechanical properties and electrical properties, and has excellent resistance to radiation, oxidation resistance, etc. Its tensile Tensile strength and heat distortion temperature are high. Aluminum electrode surface can be seen as a continuous grain edge
