光學元件在光通訊、光儲存技術、顯示器系統以及生醫流體檢測等領域有重要的應用，然而傳統的光學元件組裝複雜度高、體積與質量較大且元件之間光束對準較不易，這些因素皆使得系統成本增加。近年來應用微機電系統技術所製作之微光學元件，體積更小、質量更輕，因此反應速度更快，且使用半導體製程製作更具有批量製造的優點。因此利用微機電系統技術製作出各式微光學元件，在單一晶片上架構出自由空間微光學平台以完成一個高積集度的微光學系統，將可以大幅度地整合各種模組功能於單一晶片上。

本研究便以微光學元件中之微透鏡為主，在SOI晶片上整合UV膠微透鏡與MUMPs元件以提供一富有彈性與多樣性的微光學平台。採用UV膠點膠方式製作微透鏡具有許多優點。第一，其製作方式最為簡單(直接點膠且曝照UV光即可，也不需要光罩)，且在表面張力作用下具有良好的表面性質。第二，可在結構製作完成之後再以點膠方式製作微透鏡，因此與其他元件的整合性大幅提高。微光學平台部分，在SOI晶片上利用面型微加工製程製作出MUMPs薄膜結構元件，並整合UV膠微透鏡。其特點如下：第一，SOI晶片可以利用體型微加工製程製作厚結構元件以提供較大剛性。第二，可整合MUMPs薄膜結構的多樣性設計。第三，UV焦微透鏡與元件的整合性高。因此本研究整合UV膠微透鏡與MUMPs元件之SOI微光學平台具有元件設計多樣化、製作彈性且簡單的優點。

Micro lenses can play important roles in many micro optical systems, which applications are ranging from optical communication, optical storage, display, to biotechnology. In micro lenses fabrication, there are many advantages for UV curable polymer lens, such as high transmission, low surface roughness, and the most important thing is easy to fabricate (i.e. drip and solidification) and to integrate with other structures. However, the integration of UV curable polymer lens with complicated structures to provide various components hasn’t been reported. Accordingly, this work presents a silicon optical bench (SiOB) consisted of UV curable polymer lens, thin film MUMPs components, and thick SOI structures. For the reason that the MUMPs process is regarded as the most popular fabrication for MEMS devices and the thin film poly-Si surface micromachining also provides variety. Moreover, there are good properties for bulk silicon as actuator and fiber housing. So, the integration of UV curable polymer lens with MUMPs structure on SOI wafer is a good choice for optical application. In this work, we will demonstrate a bulk silicon optical bench with bulk silicon actuator, bulk silicon fiber clamp, and drip UV curable polymer on thin film poly-Si structure. The characterization of lens including transmission, roughness, and other optical properties will also be measured.
