这种制造技术具有用于通过现有的方法，如电子束光刻和自组装产生纳米尺度结构显著优点。首先，纳米尺度的结构可以通过使用光掩模，具有纳米柱的阵列，这是不实际的用电子束光刻工艺的大面积（整个晶片）来实现。第二，在制造过程中使用传统的晶片规模微加工过程，这是更快，更简单，更便宜相比电子束光刻。第三，在原子尺度的纳米间隙可以容易地通过ALD工艺具有精确控制的特征尺?...

太赫兹超材料（MMS）已经开发了用于生物医学传感器和频率捷装置1，2，3，4，5，6，7，8，9，10，11。为了提高太赫兹的MM传感器的灵敏度和频率选择性，基于纳米柱分割环谐振器（SRR）已经使用金（Au）的内部产生位移电流纳米柱阵列以激发具有超高品质因子的THz共振（设计Q因数）（〜450）（ 图1）12。尽管基于纳米柱-的SRR表现出高Q值和有前途的传感能力，例如nanostructur制造具有高纵横比（大于40）和纳米尺度的间隙（子10毫微米）在大面积上ES仍然具有挑战性13。 最常用的技术来制造纳米级结构是电子束光刻（EBL）14，15，16，17。然而，EBL的分辨率仍然有限，由于光斑尺寸，电子散射，抗蚀性能，以及开发过程18，19。此外，它是不实际的制造使用EBL在大面积上的纳米结构，由于一个缓慢的过程的时间和大量处理费用20。以实现纳米结构的另一种策略是使用自组装技术21,22。通过在溶液中和util的自组装金属纳米立方体（NCS）定义静电作用和NC之间的聚合物配体的协会，组织良好的一维数组NC具有纳米级的差距可以达到23。纳米间隙的大小取决于纳米晶之间的聚合物配位体，并且可以通过具有不同分子量的24，25，26施加不同的聚合物材料来控制。自组装是实现可扩展性和成本效益的纳米结构23的强大技术。然而，相对于传统的微和纳米制造工艺的制造工艺比较复杂，和纳米间隙尺寸的控制不是用于电子设备的应用程序足够精确。为了成功地制造基于纳米柱-的SRR，一种新的制造方法应该被发明，实现以下目标：i）本制造工艺很容易申请，并与约定兼容人微纳米制造工艺; ⅱ）制造在大面积上是适用的; ⅲ）纳米间隙尺寸可以用0.1纳米的分辨率可容易且精确地控制，并且可以按比例缩小至10nm或更小。 一种新的制造方法是使用电镀工艺的组合和原子层沉积（ALD）工艺来制造基于纳米柱-的SRR证明。因为电镀是低成本的自填充过程中，它很容易制造的结构在大面积上。 ALD是一种可以通过在反应循环的过程中精确地控制的化学气相沉积（CVD）工艺。 ALD薄膜的分辨率可以是0.1纳米，该薄膜被均匀地涂覆有高的质量，这是合适的，以创建纳米尺度的间隙27，28。与10纳米间隙或更少，基于纳米柱-SRR阵列可以成功地制作在6毫米×6毫米的区域。既有Simulated和测量的太赫兹透射光谱显示出具有超高Q值和大频移，这证明通过位移电流介导的基于纳米柱，SRR的可行性共振行为。详细的制造方法是在协议部分如下所述，与视频协议可帮助从业者了解的制造过程，并避免与基于纳米柱-SRR的制造相关联的常见错误。
