Abstract

In this work, complex Chinese micropatterns are experimentally inscribed in AgInSbTe thin films through laser writing technique. The overlapping inscription strategy is introduced to reduce the size of complex Chinese micropatterns, and the erosion algorithm is used to eliminate sticking effects among fine strokes in complex Chinese micropatterns. The results show that the size of complex Chinese micropatterns can be reduced to around ${15.41}\;\unicode{x00B5}{\rm m} \times {15.41}\;\unicode{x00B5}{\rm m}$. The width of the finest stroke is only 0.45 µm. This method can achieve a fidelity of 95%. This work helps with the long-term preservation of massive Chinese character archives.
