提出了一种在热塑性塑料衬底上制作微尺度特征的新方法。与传统的热塑性塑料微加工技术不同的是，主体聚合物通过机械加工或压花从基材上移位，而被称为造山微加工的独特工艺被开发出来，其中热塑性塑料表面的选定区域通过不可逆的溶剂膨胀机制从基材上隆起。造山技术允许使用各种掩模方法对热塑性表面进行图案化，从而产生通过传统微制造方法难以实现的三维特征。以环烯烃共聚物为模型热塑性材料，描述了几种不同的工艺，以实现从几纳米到几十微米的生长高度，图案化技术包括直接光致抗蚀剂掩蔽、图案化UV/臭氧表面钝化、弹性冲压和非接触斑点。造山带微制造也通过直接喷墨打印演示，作为一种快速桌面热塑性塑料微制造的简便、无光刻掩膜方法。
A new method for the fabrication of microscale features in thermoplastic substrates is presented. Unlike traditional thermoplastic microfabrication techniques, in which bulk polymer is displaced from the substrate by machining or embossing, a unique process termed orogenic microfabrication has been developed in which selected regions of a thermoplastic surface are raised from the substrate by an irreversible solvent swelling mechanism. The orogenic technique allows thermoplastic surfaces to be patterned using a variety of masking methods, resulting in three-dimensional features that would be difficult to achieve through traditional microfabrication methods. Using cyclic olefin copolymer as a model thermoplastic material, several variations of this process are described to realize growth heights ranging from several nanometers to tens of microns, with patterning techniques include direct photoresist masking, patterned UV/ozone surface passivation, elastomeric stamping, and noncontact spotting. Orogenic microfabrication is also demonstrated by direct inkjet printing as a facile photolithography-free masking method for rapid desktop thermoplastic microfabrication.
