論文主要研究鉑與錫在極短時間之反應，利用浸鍍將錫鍍在鉑基板上以產生反應，以聚焦離子束切出試片的橫截面。利用X光繞射儀觀察其成分，以掃描式電子顯微鏡以及穿透式電子顯微鏡觀察其介面之結構及介合物種類、型貌與生長狀況，並對介金屬與鉑的可能之晶向關係加以探討。
　　由浸鍍錫液1秒、2秒的試片中鑑定出，最外層的介金屬化合物為PtSn4，晶粒較為大顆且形狀為方型板狀，而靠近鉑之較薄介金屬化合物層鑑定為PtSn。以上諸相之間均無晶向關係。此結果顯示PtSn4與PtSn在迴焊之第一秒皆已生成。
　　由異質成核理論，探討PtSn4與PtSn在鉑與錫迴焊反應中，其生成先後次序之可能原因。將由PtSn4與PtSn之單位體積生成熱其與熔融錫以及與鉑之界面結構。

The purpose of this research is to study the early stage reaction between Pt and Sn. Pt substrate was immersed into molten Sn for 1, 2 and 10 seconds and the cross-section specimens was cut by focused-ion beam.
The results were analyzed by X-ray diffraction, and transmission electron microscopy (TEM) to study the microstructure, and the type, shape and the growth conditions of intermetallic compounds (IMCs). the possible orientation relationships between Pt and IMCs are analyzed.
TEM results showed that PtSn4 was on the surface of the specimens reflowed for 1 s and 2 s, and had a shape of square plate. However, a thin layer, 10 -20 nm, of PtSn was observed next to Pt substrate. There is no orientation relationships among Pt, PtSn and PtSn4. It is clear that both PtSn and PtSn4 are formed in the first second.
The formation of PtSn and PtSn4 was analyzed by heterogeneous nucleation theory, including the free energies of formation, and their interfacial energies with respect to Pt and molten Sn.
