Abstract:
A back of a dielectric transparent handle substrate is coated with a blanket conductive film or a mesh of conductive wires. A semiconductor substrate is attached to the transparent handle substrate employing an adhesive layer. The semiconductor substrate is thinned in the bonded structure to form a stack of the transparent handle substrate and the semiconductor interposer. The thinned bonded structure may be loaded into a processing chamber and electrostatically chucked employing the blanket conductive film or the mesh of conductive wires. The semiconductor interposer may be bonded to a semiconductor chip or a packaging substrate employing C4 bonding or intermetallic alloy bonding. Illumination of ultraviolet radiation to the adhesive layer is enabled, for example, by removal of the blanket conductive film or through the mesh so that the transparent handle substrate may be detached. The semiconductor interposer may then be bonded to a packaging substrate or a semiconductor chip.
