Abstract:
A method includes forming a release film over a carrier, forming a polymer buffer layer over the release film, forming a metal post on the polymer buffer layer, encapsulating the metal post in an encapsulating material, performing a planarization on the encapsulating material to expose the metal post, forming a redistribution structure over the encapsulating material and the metal post, and decomposing a first portion of the release film. A second portion of the release film remains after the decomposing. An opening is formed in the polymer buffer layer to expose the metal post.

Claim (Index 8):
A method comprising: coating a Light To Heat Conversion (LTHC) coating material on a carrier;\n forming a polymer buffer layer over the LTHC coating material; forming a metal seed layer in contact with the polymer buffer layer; forming a patterned photo resist over the metal seed layer, with a portion of the metal seed layer being exposed through an opening in the patterned photo resist; plating a metal post over the metal seed layer; removing the patterned photo resist; etching the metal seed layer to expose the polymer buffer layer; projecting a laser beam on the LTHC coating material, wherein a working range of the laser beam covers a first portion of the LTHC coating material, and a second portion of the LTHC coating material is out of the working range; lifting off the carrier; and forming a solder region penetrating through the second portion of the LTHC coating material.
