Imprinting on various substrates
Photonic crystal, PSS(*) (μm, nm), microlens array
(*) PPS: Patterned Sapphire Substrate
High-precision imprinting of the photonic crystal, PSS (Patterned Sapphire Substrate) for use in high-brightness LED, and microlens array is available.
Batch press imprinting allover φ2 - φ4 inches substrate
This imprint method can follow a warped surface and regional micro-spikes.
Mechanism of following imprinted surface and uniform distribution of imprinted surface pressure enables highly efficient imprinting.
