<p>A method for bonding of disk shaped substrates comprises the steps of providing a first and a second substrate, applying a liquid adhesive to a first bonding surface and a second surface, irradiating the lacquered surface of at least one of the substrates with UV light for increasing the viscosity of the lacquer, joining the substrates in vacuum, irradiating the joined disk with UV light for increasing the viscosity of the lacquer in between the joined disks, placing the disk onto a rotatable chuck, rotating the disc with a rotation speed preferably >500rpm, and finally separating the 2 substrates to leave the full bonding layer on one of the substrates.</p> |
