| Abstract: | The technology of femtosecond laser two-photon polymerization micromachining plays an important role in the micro-nano-processing-related fields. However, in many cases, the equipment for femtosecond laser two-photon polymerization processing cannot prepare microstructures on non-transparent substrates due to the problems rising from optical path. Based on the structure of the non-changing two-photon polymerization micromachining equipment, the authors introduce the use of a surrounding alphanumeric spiral tower for lithography on two non-transparent substrates represented by copper and silicon wafers. By observing the lithographic pattern, the effective lithographic distance interval and the optimal lithography distance on the copper and silicon wafers are respectively obtained. The two-dimensional and three-dimensional patterns are lithographically etched on two non-transparent substrates respectively. The clearly obtained pattern indicates that the lithography method is effective and feasible for the non-transparent substrate. In this research, supported by the results, the methods are summarized for lithography of two-photon polymerization equipment on non-transparent substrates, which facilitates two-photon polymerization in optical micro-devices, MEMS, and biological tissue engineering. |
