几种微/纳米制造技术的发展导致了支持当今科学技术的微/纳米器件的许多创新。随着特征的小型化，制造工具已经从光转移到电离辐射。在这里，我们提出了一种利用电离辐射的扫描光束(SB)对有机材料进行微/纳米加工的简单技术。通过Sb的三维能量沉积分布来控制材料的断裂/交联，适当的溶剂可以很容易地从块体材料中只剥离交联区。这项技术是用聚焦离子束和氯化有机聚合物演示的。该聚合物在辐照时主链发生断裂，但在高剂量辐照后发生交联。适当的溶剂可以很容易地从块状材料上只剥离交联区。这项名为“来自纳米球的纳米棒”的技术使人们能够生产出所需的结构，如纳米线和纳米膜。它还可以应用于功能材料的微/纳米加工。
The development of several kinds of micro/nanofabrication techniques has resulted in many innovations in the micro/nanodevices that support today's science and technology. With feature miniaturization, the fabrication tools have shifted from light to ionizing radiation. Here, we propose a simple micro/nanofabrication technique for organic materials using a scanning beam (SB) of ionizing radiation. By controlling the scission/crosslinking of the material via three-dimensional energy-deposition distribution of the SB, appropriate solvents can easily peel off only the crosslinked region from the bulk material. The technique was demonstrated using a focused ion beam and a chlorinated organic polymer. The polymer underwent main-chain scission upon irradiation, but it crosslinked after high-dose irradiation. Appropriate solvents could easily peel off only the crosslinked region from the bulk material. The technique,'nanobead from nanocup', enabled the production of desired structures such as nanowires and nanomembranes. It can be also applied to the micro/nanofabrication of functional materials.
