摘要: This paper is to explore a dual-curvature with dual-focus microlens array fabrication by diffuser lithography process. First part is to combine the diffuser lithography and hot-melt method by using JSR-126 and AZ-4620 photoresists to produce dual-layered microlens array. Second part is to design different sizes of upper and lower masks, as well as simulation and measurement. In first part, the research is to produce lower curve microlens by using diffuser lithography and JSR-126 negative photoresist. Then upper curve microlens is produced by using melt method and AZ-4620 positive photoresist. The research is exploring related dimensions of lower layer and upper layer masks for such dual curvature microlens, and using the optical simulation software TracePro to measure the light energy distribution. The results showed combined with the lower layer with 100 μm and upper layer with 75 μm may result in uniform light distribution. It can be concluded the lower and upper mask layers with the 3/4 ratio is the best effect.
本研究使用擴散微影法的製程方式,去探討具有不同曲率的雙層微透鏡陣列,研究分為兩個部份,第一個部分是結合擴散微影法與熱熔法的製程方式,並使用JSR-126負光阻與AZ-4620正光阻來製作雙層微透鏡。第二部分為設計不同的上下層光罩尺寸,並進行模擬量測。在第一部分中,以擴散微影法與JSR-126負光阻製作下層微透鏡,再以熱熔法與AZ-4620正光阻製作上層微透鏡,此法具有製程簡易與成形快速之優點。而在第二步是去探討上下層光罩尺寸的搭配,再利用光學模擬軟體TracePro去量測其光能量分布,發現下層100 μm、上層為75 μm之尺寸搭配,能量分布最為均勻,推論出上下層比例為3/4之光罩效果最佳,進而得以完成雙層雙焦點之微透鏡陣列。
