Abstract:
A method for forming a data storage device comprising:providing a first wafer and a second wafer, the first wafer and second wafer being configured to define therebetween an interior chamber; providing a vacuum chamber, the vacuum chamber defining a first zone; placing the first wafer within the vacuum chamber; maintaining the first wafer under vacuum pressure within the vacuum chamber; depositing storage media upon the first wafer; removing contaminants from a vicinity of the first wafer; bonding the first wafer and the second wafer together to form a wafer stack such that the interior chamber is maintained under vacuum pressure after the first wafer and second wafer are bonded together; and providing a first chamber selectively pneumatically communicating with the first zone such that, when the first chamber is not pneumatically communicating with the first zone, the first wafer can be placed in the first chamber, and when the first chamber is pneumatically communicating with the first zone, the first wafer can be transported from the first chamber and into the first zone.
