面型微加工製造技術乃根源於積體電路的平面製程技術，因此製作而成的元件大抵以二維的方式展現，在許多應用上間接受到了限制。本文針對微結構組裝的方法進行討論，並企圖以薄膜殘餘應力、光阻及超音波激振等組裝方法，達成微結構自組裝的目的。並以三維微光開關之組裝設計為主軸，進行結構設計方面之研究，以提升其精密定位之程度。
透過自行開發之MUMPs-Like面型微加工製程，本文完成以薄膜殘餘應力自組裝之三維微光開關元件，其中使用介電薄膜取代金屬薄膜，藉由可靠度測試驗證，其應力鬆弛的問題確可大幅改善。本文並針對元件之性能進行定性及定量測試，藉此提出改良之定位機構，期能藉此製作高定位精度之三維微元件，並提供微結構一更可靠及穩定的組裝方式。

Surface micro-machining technology is based on the planar integrated circuit process. Due to the nature of surface micro-machining process, a fundamental problem is its inability to produce highly 3D structures. Therefore, the applications may be limited. To accomplish 3D devices after the process, residual stress of thin film, photo-resist, and ultrasound are adopted to be the self-assembly approaches. Design and fabrication of 3D optical switch is employed to demonstrate the mechanical positioning mechanisms, such as latch and hinge.
Based on the MUMPs platform, this study has established an improved surface micromaching process (MUMPs-like process). Through this process, the stress-induced self-assembly 3D optical switch has been realized. According to the result of reliability test, stress relaxation is significantly reduced using the dielectric film instead of the metal film. Furthermore, this study intends to present a novel positioning mechanism for MEMS, particularly for micro-optical devices. Relied on that, more robust and reliable self-assembly mechanism is achieved.
