整合奈微機電製程應用於矽質基板上製作具有奈微結構複合表面，以化學氣相沈積技術疏水性分子(FDTS,CF3(CF)7CH2CH2SiCl3)使該表面具備有極端疏水性、低遲滯效應與超抗沾黏特性。對照接觸角理論預測與實驗量測之數據，根據本專利所設計奈微結構設計，控制其反應時間，能夠有效大幅增強並且大範圍調控表面之疏水性，使得接觸角從112°提升至173.1°。
Hybrid-structured surfaces consisting of microgrooves and nanocrystals have been modified with a self-assembled monolayer (CF3(CF)7CH2CH2SiCl3) via low-cost, mass-production, and highly integrated nano/microfabrication. The microgrooves decorated with nanocrystals were patterned and fabricated on a silicon substrate to yield an ultrahydrophobic surface with an anti-sticking property. The nanocrystals were etched by means of oxidation of the silicon surface. Comparison of contact angles for microdroplets on those designed surfaces showed that the hydrophobicity of the solid surfaces became amplified with nanocrystals and accurately modulated with a pattern density (f1), ranging from 112 DEG to 173.1 DEG
