Hot Embossing Systems

EV Group’s series of high-precision hot embossing systems are based on the company’s market-leading wafer bonding technology. Excellent pressure and temperature control as well as uniformity over large areas allow for high accuracy imprints. Hot embossing is a cost-effective and flexible fabrication technology with very high replication accuracy for feature sizes down to 50 nm. The systems are well suited for embossing complex micro- and nanostructures and high-aspect ratio features into a wide range of polymer substrates or spin-on-polymers. The combination with stamp-to-substrate alignment allows alignment of hot embossing to pre-processed substrate structures.
