Abstract
A method for manufacturing one or more optical devices, each comprising a first member and a second member, and a spacer arranged between the first and second members. The method includes manufacturing a spacer wafer including a multitude of the spacers. Manufacturing the spacer wafer includes providing a replication tool having spacer replication sections; bringing the replication tool in contact with a first surface of another wafer; bringing a vacuum sealing chuck into contact with a second surface of the other wafer while the other wafer remains in contact with the replication tool; and injecting a liquid, viscous or plastically deformable material through an inlet of the vacuum sealing chuck so as to substantially fill the spacer replication sections.
