Directed Self-Assembly (DSA) lithography is an emerging nano-fabrication technology with potential to revolutionise the semiconductor industry. DSA lithography is a technique which uses self-assembling block copolymers (BCP) to create nanoscale patterns.
These block copolymers are polymers that are made up of two or more chemically distinct polymeric blocks which have a tendency to self-assemble into intricate patterns. The unique combination of the different blocks of polymers can be used to create patterns with feature sizes below the optical lithography limit.
DSA lithography provides a way to reliably fabricate nanostructures with low cost and high yield. In DSA lithography, a mask is not required and the pattern is produced by self-assembly of the block copolymers.
This process occurs in a solution and is achieved through a combination of thermal annealing and solvent annealing. Through this process, the block copolymers form into nanoscale patterns that can be used for various applications such as photonics, biosensors, and transistors.
The advantages of DSA lithography compared to traditional lithography methods include: lower cost, higher resolution, and faster turnaround. Additionally, it is more efficient and provides more precise control over the pattern formation process. Furthermore, the process is environmentally friendly and does not require the use of hazardous chemicals.
In conclusion, DSA lithography is a promising technology that could revolutionise the semiconductor industry. It is a process that offers a cost-effective, high-resolution, and efficient way of fabricating nanostructures with low cost and high yield. This technology will enable us to make smaller and more precise devices, which could lead to new possibilities in many industries.
