Patent ID: 7851266

Claim:
A method of molding a liquid adhesive onto a microelectronic device wafer, comprising: positioning the wafer in a mold cavity, the wafer includes a first face, a second face, an edge between the first and second faces, and a plurality of semiconductor dies with integrated circuits at the second face; flowing a predetermined volume of the liquid adhesive onto only the first face of the wafer in the mold cavity, the predetermined volume of the liquid adhesive being determined based on an area of the first face and a target adhesive thickness; exerting a force against the liquid adhesive so as to mold an adhesive layer onto the wafer; heating the adhesive layer to a first temperature; cooling the adhesive layer to a second temperature lower than the first temperature; removing the wafer with the adhesive layer from the mold cavity; singulating the wafer with the adhesive layer into a plurality of wafer portions, individual wafer portions including a die; and adhering an individual wafer portion to a substrate, the adhering includes heating the wafer portion to a third temperature greater than the second temperature.
