摘要

運用熱壓印於聚合物進行微製造是一個具有經濟效益的方法。由於全球競爭的壓力，微元件必須以便宜與很快的速度來研發、製造與導入市場，因此本研究提出一項可以縮短熱壓印製程脫模時間之混合快速模具製作技術，研究結果發現，運用紅銅、鋁材以及模具鋼為背襯材料所製作之混合快速模具，如與運用傳統方法所研製之金屬樹脂熱壓印模具比較，實際提升熱壓印脫模時間效率分別約為78%、68%以及50%。運用四種不同背襯材料所製作之快速模具之深度或寬度之翻製率均可達96%以上，熱壓印之微結構深度與寬度轉寫率均可達93%以上。

Hot embossing is a cost-effective approach for polymer-based microfabrication. Micro devices must be more quickly and cheaply developed, manufactured and introduced to the market due to the pressure of global competition. This work demonstrates a technique to fabricate hybrid rapid tooling for reducing demolding time during micro-hot embossing molding process. It was found that the demolding time efficiencies for the hybrid rapid tooling produced by the backing materials of copper, aluminum and steel about 78%、68 % and 50% can be enhanced compared to that of the traditional rapid tooling. The replication rate exceeding 96% in the hybrid rapid tooling manufacturing process can be reached. The transcription rate exceeding 93% in the micro-hot embossing molding process can be obtained.
