Effect of triazene polymer film on the Ag micro-stripe prepared by LIIFT technology

Triazene polymer (TP) film was used as the intermediate layer to transfer the Ag micro-stripe in laser interference induced forward transfer (LIIFT). The results showed that the film quality of the intermediate layer would affect the transfer results. The homogeneity of the TP films would affect the completeness and resolution of the transferred Ag micro-stripe. Applied the TP1 film compounded by the solution with higher concentration (20 g/L) of 1,3-diphenyl-1-triazene (DT) and tetrahydrofuran (THF), there was shown scattered Ag nanoparticles (NPs) instead of micro-stripe on the Si receiver. Reducing the solution concentration, with the intermediate layer of TP2 film, the broken micro-stripe was transferred. While the TP3 film was prepared with DT and N, N-Dimethylformamide (DMF) solution and used as the intermediate layer, the unbroken and regular Ag micro-stripe with good resolution was transferred, indicating the TP3 film was more appropriate than TP1 and TP2 films as the intermediate film to transfer the Ag micro-stripe in LIIFT. Combined with the analysis to the film qualities, the effect of the film homogeneity on the transferred results was discussed.
