Patent ID: 7901988

Claim:
A method for forming a package-on-package structure, the method comprising: securing a first semiconductor package having at least one encapsulation layer formed on at least one side of the first semiconductor package to a surface of a support, the at least one encapsulation layer defining a first thickness, the surface being adapted for receiving the first semiconductor package; directing fluid onto a portion of the at least one encapsulation layer distal the surface; and reducing the first thickness of the at least one encapsulation layer to a second thickness by way of grinding the portion of the at least one encapsulation layer, wherein the first thickness of the at least one encapsulation layer is reduced for providing a clearance from a second semiconductor package attachable to the first semiconductor package, the clearance being the distance between the at least one encapsulation layer of the first semiconductor package and a side of the second semiconductor package opposing thereto.
