摘要

对介电偶极子的介电频率色散、弛豫时间等弛豫特性进行了表征,指出了在结构材料设计中应优化的特性。利用Cole-Cole图表征光阻材料的介电偶极子弛豫时间,利用传统电容法确定聚合物结构中介电偶极矩在10mHz ~ 5MHz频率范围内的介电弛豫时间。干膜抗蚀剂的松弛时间(DFR)可确定为12.5 s。讨论了DFR薄膜作为结构材料的介电性能的有效性。

Relaxation properties of dielectric dipoles of photo resist materials
Relaxation properties of dielectric dipoles such as dielectric frequency dispersion, relaxation time, which should be optimized in structural material designing, are characterized. Relaxation times of dielectric dipoles of photo resist materials are characterized by Cole-Cole plot, which is employed to determine a dielectric relaxation time of dipole moment in polymer structure, based on traditional capacitance method in frequency range of 10mHz to 5MHz. The relaxation time of dry film resist (DFR) can be determined to be 12.1s. The validity of dielectric properties of DFR film as a structural material is discussed.
