基于微型化的持续趋势，并且由于MEMS技术的复杂性增加，需要开发新的组装方法。最近的发展表明，特别是光学力适合于满足要求。光镊（OT）由于其非接触和精确的操作力而具有独特的优势。通过使用由空间光调制器（SLM）产生的适当光束轮廓，已经可以任意组装球形以及非球形预成型件，从而产生所谓的全息光学镊子（HOT）设置。为了制造形状互补的预成型件，实施双光子聚合（2PP）过程。2PP和HOT工艺组合的目的是开发用于组装任意构建块的光学微处理平台。在此，描述了2PP和HOT工艺的优化，以允许互锁部件的制造和3D组装。结果包括低和高质量的2PP微结构和它们的制造精度的进一步热组装工艺的依赖性的分析。并通过应用实例对2PP砌块可拆式联锁连接的应用进行了可视化。因此，从长远来看，可以实现不施加任何机械力的完全光学组装方法。
Based on an ongoing trend in miniaturization and due to the increased complexity in MEMS-technology new methods of assembly need to be developed. Recent developments show that particularly optical forces are suitable to meet the requirements. The unique advantages of optical tweezers (OT) are attractive due to their contactless and precise manipulation forces. Spherical as well as non-spherical shaped pre-forms can already be assembled arbitrarily by using appropriate beam profiles generated by a spatial light modulator (SLM), resulting in a so called holographic optical tweezer (HOT) setup. For the fabrication of shape-complementary pre-forms, a two-photon-polymerization (2PP) process is implemented. The purpose of the process combination of 2PP and HOT is the development of an optical microprocessing platform for assembling arbitrary building blocks. Here, the optimization of the 2PP and HOT processes is described in order to allow the fabrication and 3D assembling of interlocking components. Results include the analysis of the dependence of low and high qualities of 2PP microstructures and their manufacturing accuracy for further HOT assembling processes. Besides, the applied detachable interlocking connections of the 2PP building blocks are visualized by an application example. In the long-term a full optical assembly method without applying any mechanical forces can thus be realized.
