The invention has the advantages that by means of single film growth craft, supporting structures of a pier, a bridge leg, and a deck are accomplished, thus greatly lowering the difficulty and complicity of the craft; the pier, the bridge leg, and the deck are formed into a trinity, thus assuring the mechanical support of the whole micro bridge to be firmer and to have higher stability; meanwhile, the pier manufactured by means of the single film growth craft has a hollow shape, thus ensuring that the manufacturing process of the electrical channel of the micro-bridge structure is more simple, without the need of tapping in the pier; only simple photoetching craft is needed to guarantee the connection between the electrode at the upper end and the electrode at the lower end.

本发明利用一次薄膜生长工艺完成桥墩、桥腿和桥面的支撑结构，大大降低了工艺难度和复杂性，且桥墩、桥腿和桥面三位一体，使得整个微桥的机械支撑更为牢固，稳定性更高；同时，本发明利用一次薄膜生长工艺制作出的桥墩成空心状，使得微桥结构的电学通道制作过程变得更为简单，无需另外在桥墩中开孔，只需简单的光刻工艺即可保证上端电极和下端电极相连。
