1Productivity
If conventional top-down or bottom-up techniques are used for nanostructure fabrication, then existing methods can produce nanostructures, but they are deficient in high-throughput fabrication of functional nanostructures with complex geometries
Solution Approach 1:
The system segments the fabrication process into distinct modules: a dispensing module that deposits material in programmable patterns, a superstrate handling module that manages flexible web substrates, and a curing module that solidifies the deposited material. This segmentation enables high-throughput production while maintaining precision for complex geometries through coordinated operation of specialized subsystems.
Solution Approach 2:
The system utilizes programmable parameters including dispensing patterns, superstrate movement speeds, curing conditions, and thickness specifications to achieve high-throughput fabrication of complex nanostructures. The ability to dynamically adjust these parameters allows the system to produce varied complex geometries efficiently without sacrificing precision.
2Manufacturing precision
If material is dispensed using conventional methods, then material deposition is achieved, but precision control and alignment with microscale accuracy are not achieved
Solution Approach 1:
The system replaces conventional mechanical dispensing methods with a programmable dispensing module that uses digital control to achieve microscale pixel accuracy. This substitution of mechanical systems with programmable control enables precise material deposition while maintaining high fabrication throughput through automated operation.
Solution Approach 2:
The system uses a programmable pattern template that can be copied and applied across the substrate surface with microscale precision. The dispensing module reproduces desired geometries by following digital patterns, enabling high-throughput fabrication of complex nanostructures with consistent microscale accuracy across large areas.
