中文摘要
本研究探討Ag-Al-Sb及Ag-Al-Zn三元系統在500℃之等溫橫截面相圖,可以用來作為半導體封裝製程中新型銀合金打線開發的參考依據。實驗主要利用熱壓擴散偶進行界面相平衡的研究,並以特定合金單點試片的相平衡結果來輔助,利用電子微探儀(EPMA)進行擴散介面影像的擷取及各相成分分析,實驗結果加以統整後可得到整體相平衡的關係來完成此兩個三元系統等溫橫截面相圖。 根據實驗結果可以成功接合此二個三元系統的擴散偶,並再配置特定成分合金試片經過30天500℃的時效熱處理,可以確認且修正以上擴散偶的結果;Ag-Sb-Al 三元系統在500℃等溫橫截面相圖共計有6個三相區為Al/Ag2Al/AlSb 、Ag7Sb/Ag13Sb3/AlSb、Ag/Ag2Al/AlSb、Ag/Ag7Sb/AlSb、Ag13Sb3/L/AlSb及L/AlSb/Sb;而Ag-Zn-Al三元系統在500℃等溫橫截面相圖共計有2個三相區為Ag/AgZn/ε及AgZn/Ag5Zn8/ε,並量測出以往量測中所缺少的富銀區資訊,即Ag、AgZn相的固溶範圍,ε相固溶範圍也與文獻相似,但隨著相平衡溫度提高其固溶範圍往富銀端移動。
Abstract
The 500oC isothermal cross-sectional phase diagrams of Ag-Al-Sb and Ag-Al-Zn ternary systems are determined in this study, which can provide the phase stability information for development of new silver wirebonding in semiconductor packaging process. The interfacial phase equilibrium is generated by the hot pressed diffusion couple method, and the phase equilibrium data of the specific alloy samples can comfirm and complete whole phase diagram regions. The equilibrium phases are examined by using electron probe micro-analyzer(EPMA). According to the experimental results, the diffusion couple of these two ternary systems can be successfully produced and the specific composition alloy specimen can be confirmed and fixed by the aging heat treatment at 500 ℃ for 30 days. There are six three-phase regions in the 500℃ isothermal diagram of Ag-Sb-Al ternary system, which are Al/Ag2Al/AlSb, Ag7Sb/Ag13Sb3/AlSb, Ag/Ag2Al/AlSb, Ag/Ag7Sb/AlSb, Ag13Sb3/L/AlSb and L/AlSb/Sb. There are two three-phase regions in the 500℃ isothermal diagram of Ag-Zn-Al ternary system,which are Ag/AgZn/ε and AgZn/Ag5Zn8/ε. Finally, the solid solution range of Ag and AgZn phases can be delimit, which is lacking in previous measurement.
