A facile and scalable fabrication method of highly periodic array of nano-sized voids with large area (182 cm²) has been achieved by means of a template related 3-step procedure. A non-close packed (NCP) colloidal SiO₂ array was fabricated by programmed spin-coating and in situ polymerization. The colloidal SiO₂ arrays are embedded in a polymer matrix, and the spheres of the top layer protrude out of the film, forming a periodic surface. After being etched by HF aqueous solution, the first layer of SiO₂ microspheres in the template were etched off and left behind a highly periodic hexagonal array of polymer nanovoids. The periodicity of the resulting polymer nanovoids array is the same as that of colloidal SiO₂ arrays. The volume of nanovoid is as small as about 4.72 attoliter per void, and the density of voids can be as high as about 4.9×10⁸ voids/cm². The metallic nanovoids array could be fabricated by subsequent deposition of Cr and Au layers. The resulting array of metallic nanovoids could be used as surface-enhanced Raman scattering (SERS) active substrates with ultra-sensitivity and excellent reproducibility. The SERS performance of our nanovoids array was probed by benzenethoil. The SERS enhancement factor (EF) can be as high as in the order of 10⁸～10⁹ on average over 182 cm². The mean relative standard deviation (RSD) of EF is in the range of 5.5% to 8.6% over 182 cm² which indicates the reproducibility of the substrates is quite good. The methodology leverages the high uniformity of the spin-coated colloidal arrays and well-established physical vapor deposition techniques. The formation of nanovoids array with high periodicity over large areas could lead to important technological applications in nanoelectronics and sensors.

Key words: array of nano-sized voids, surface-enhanced Raman scattering, SERS active substrates, enhancement factor, reproducibility
