    • 隨著半導體技術的不斷進步與電子產品的微小化趨勢下，傳統的機械方式取放元件(Pick and Place)已不敷使用，為克服元件微小化所產生夾持與定位及生產成本等問題，流體自我組裝FSA (Fluidic Self-Assembly)的應用愈來愈廣泛。大多數的研究是將元件沉浸在流體中，以重力作用或流體流動，觀察元件組裝情形。另有一部份則研究疏水性元件浮於液面上，在無人為外力作用下，利用液體表面張力之自我組裝現象。本研究則針對此表面張力所產生的自我組裝現象進行實驗，以3mm X 3mm、2mm X 4.5 mm及1mm X 9 mm之相同截面積之矽晶片，使用OTS (Octadecyltrichiorosilane)改質成疏水性表面，放置於液面上並固定起始距離為20mm時，輔以不同疏水性之圓棒施加牽引力，探討相同截面積之矽晶片與不同疏水性圓棒的牽引力下的自我組裝現象，並以不同的速度驅動疏水棒，以及不同的行進距離進行實驗，由此實驗結果，希望能找出流體表面自組裝之最佳機制。而實驗結果發現，對欲產生自組裝之元件施以導引力加速其自組裝之完成是可行之方式。

    With the advances in semiconductor technology and the miniaturization of electronic products, the conventional method of Pick and Place is becoming inadequate to meet the production cost and clamping/ positioning problems due to component miniaturization. Thus, more and more approaches of Fluidic Self-Assembly (FSA) are developed. Most of the researches are about components immersed in fluid, and using gravity and fluid flow for assembly. And few of those researches are about the Self-Assembly (SA) without external force, which use hydrophobic components floating on the fluid surface by surface tension. In this study, the phenomenon of Self-Assembly of hydrophobic components floating on fluid surface by surface tension was investigated. Both 3mm x 3mm, 2mm x 4.5mm, and 1mm x 9mm silicon chips of the same area were used; their hydrophobic surfaces were treated by OTS (Octadecyltrichioroslane) surface modification. With an initial distance of 20mm between the components on the fluid surface, a driving force made by different cylinders with different hydrophobic properties was also provided. The SA with the same area but with different driving force, driving speed, moving distance was conducted with the hope of finding the best method of FSA.
