摘要: 采用光刻及离子束蚀刻技术制作面阵石英DNA芯片模版,利用扫描电子显微镜(SEM)和表面轮廓仪测试了所制石英DNA芯片模版的表面微结构形貌特征,分析了所制石英DNA芯片模版出现图形畸变的原因。所用工艺为在其它衬底材料表面制作更大规模及具有复杂结构的大面阵DNA芯片模版奠定了基础。Abstract: The DNA microarray plates in quartz glass substrates are fabricated using a multiple-process, including photolithography, heat treatment, and ion beam etching. Both the scanning electron microscope and surface style measurement are carried out to determine the dimension and the surface morphology of the devices. The reason of the shape distortion of DNA microarray plate in quartz glass substrate is analyzed. The coupling method of the quartz glass plate and the DNA sample is discussed. The techniques utilized can be applied to fabricate the DNA microarray plate of larger.
