硅表面上构筑具有化学特性的图形的新方法
A New Method to Pattern Silicon Surface with Chemical Functional Groups
【摘要】 为了在硅基底上得到不同化学基团修饰的图形,在氢终止硅(lll)表面运用光刻技术和光化学反应结合来控制表面成膜反应的位置,并用AFM、XPS、接触角测定等验证了这种方法的可行性.
【Abstract】 Hydrogen-terminated silicon surface was found to react with 1 -alkenes to produce stable monolayers. To pattern such monolayers and create surfaces with regions of different chemical functionalities, we used the combination of the photolithography and the light induced alkylation. The surfaces had been characterized by XPS, AFM, and contact angel measurement. It is shown that this procedure can be used to prepare mi-cro-patterns of chemical functional groups on silicon substrate.
