Periodic structures of Si(001) and quartz glass
master-matrices with the period of 4 μm and the polymer replicas
fabricated by imprint lithography and UV light hardening
techniques were investigated. The profile of the structures was
examined by atomic force microscopy. Diffraction efficiency of the
periodic structures was measured experimentally and calculated
theoretically employing the integral technique. The results
obtained show the diffraction efficiency to be an efficient tool
for the control of surface relief formation during etching of
master-matrix and its replication. It is shown that the quartz
glass master-matrix is more efficient both for the imprint and UV
hardening polymer replication as compared to the silicon one.

Naudojant standartinius litografinius ir
cheminio bei plazminio ėsdinimo technologinius metodus,
kristaliniame silicyje (100) ir kvarciniame stikle buvo suformuoti
periodiniai dariniai, kurių periodas d = 4 μm,
profilio gylis h = 0,5 μm. Dariniai buvo antrinami
polimerinėse medžiagose (polimetilmetakrilate, akriliniame
trimetilolpropanetoksilate), naudojant įspaudimo ir UV kietinimo
metodus. Atlikti periodinių darinių difrakcinio efektyvumo
eksperimentiniai ir teoriniai (naudojant PCGrate 2000MLT programą)
tyrimai. Atlikta įvairių technologinių procesų įtakos periodinių
darinių difrakciniam efektyvumui analizė. Darinių paviršiaus
reljefo morfologijos tyrimai atlikti atominių jėgų mikroskopu
NT-206, optinio atsako tyrimai – naudojantis lazeriniu (λ =
632,8 nm) difrakcijos stendu.
