Nanoimprint Technology: Three Questions You Should Definitely Ask!

By overcoming several miniaturization odds, Nanoimprint has emerged as one of the most trusted technologies in the high-tech world. So, to ensure that the technology delivers the maximum results, you must ask the following three questions:

How Nanoimprinting is done? 

Nanoimprinting technology uses a simple approach without the need for any expensive optics, light sources with shorter wavelengths, and multiple patterning machines. This helps in the reduction of the overall imprinting cost and minimization of the chip failure rates.

  • The nanostructured polymer or silicon mold is formed by pressing beneath the chambers with controlled pressure.
  • While pressing the mold, the moderate temperature is maintained as per the level of the substrate coating layer on the polymeric material.
  • The mold is then carefully removed and as a result, the characters are imprinted on the substrate in an inverse manner.

What are the different Nanoimprinting techniques? 

Depending on your requirements, you can choose the following nanoimprint techniques.

  • Hot embossing: Under this method, the polymer films are structured and embossed by heating it above the glass transition temperature. As compared to other methods, this technique provides benefits such as elimination of defects and low-cost macro-scale embossing, which makes it an ideal solution for optical applications where high precision and high quality is required.
  • UV-based Nanoimprinting: In this process, a photo-curable resist is employed in order to withstand the UV-light exposure. This technique facilitates multi-level patterning that can be performed without generating thermal gradients. Further, the required stamps can be easily obtained through casting and curing a liquid precursor onto a silicon master.

Why you should use Nanoimprint technology? 

Over a period of time, this technique has substantially become a realistic method for commercial semiconductor production. It comes with benefits like high precision, high throughput, and the potential to effectively replicate nanoscale features.

Here are some common applications of nanoimprint technology:

  • Fabrication of photovoltaic layer in solar cells, high-density magnetic recording, and assembling media for hard-disk drives.

  • Biological devices like Nano-fluidic devices and sensors for DNA stretching and tissue engineering.
  • Advancement of ICs and semiconductors while manufacturing nanostructures.
  • Used in compact sensors for the detection of chemicals, such as pesticides and bacteria.

Due to its robust features, nanoimprint technology is considered as one of the best alternatives to conventional lithographic technology. In the near future, it is expected to occupy a strong place in several disciplines.
