本文提出應用於掃描試探針顯微鏡(SPM)的二階式微進給系統，其主要由粗進給系統、細進給系統與定位系統三部份組成。粗進給系統以高放大率的撓性機構，將「山形」熱致動器(Chevron beam thermal actuators)輸出的小位移放大，提高裝設在放大機構上之粗定位平台(Coarse stage)的移動速度及行程距離(60μm)。當粗進給平台位移至特定位置後，由撓性雙穩態機構與熱致動器構成的定位系統固定粗進給平台，此定位系統具有抗干擾與維持進□系統於穩定位置並無消耗能量的特點。細進給系統以具有奈米精度的爬舉式致動器(Scratch driven actuator)為致動器並以70V的偏壓20V的正弦波驅動細進給平台(Fine stage)，使其具有30nm的解析度，最大輸出力量165μN。另一方面，以實驗結果說明卡氏原理(Castigliano’s theorem)可運用於分析撓性機構的運動並與商用軟體ANSYS及pesudo-rigid-
body model模擬結果有相同的趨勢。另外，本文所提之線性微進給系統均可由面型微加工製造完成。

This paper proposes a design methodology for a two-stage linear micro-feeding system that includes a coarse-feeding subsystem, a fine-feeding subsystem and positioning subsystem. The coarse stage is driven by an array of thermal actuators through a compliant amplification mechanism. This gives it the ability to generate a rapid and long range of motion. When the coarse-feeding subsystem is moved to the desired position, the system is clamped by the positioning subsystem that features two compliant bistable mechanisms. The coarse-feeding subsystem has a range of 60 μm with a resolution of 3 μm. After the coarse stage moves into the desirable position, the scratch drive actuator shifts the fine stage to the desired position over a small range of 4 μm, with a large force of 165 μN, and a high resolution of 30 nm at a bias of 70V with an additional sine wave of amplitude 20V. Additionally, the pseudo-rigid-body model and Castigliano’s theorem were employed to derive the strain energy and the relationship between the output and input displacements of the amplification mechanism. These theorems were tested and matched the experimental results. The results of the experiments performed support the pseudo-rigid-body model and the widely accepted Castigliano’s method. The proposed micro-feeding system was fabricated by the MUMPs, which was provided by MEMSCAP.
