Solving the Supply Chain Challenge
In addition to producing miniaturized photonic devices for AR/VR headsets, SLR cameras and smartphones, this sub-micron capability has broader applications for micro lenses in several other exciting areas. For example, the technology can be used to produce hydrogels and biopolymers for use in contact lenses, biosensors for detecting COVID-19 and other pathogens with a very low concentration of material through spectral analysis, and other applications in the semiconductor industry.
“3D-printing has taken over many other manufacturing processes, the only thing left is printing in submicron resolution,” Das Gupta said. “This technique has the potential to reduce the cost and drive drastic change in the semiconductor industry by eliminating the clean room requirement and making production much faster.”
In addition, Das Gupta says, “It also reduces the carbon footprint of the entire production process and could dramatically improve supply chain resiliency, allowing companies to produce and procure chips much closer to home.”
