Patent ID: 7150390

Claim:
A method for encapsulating a flip chip, the method comprising the steps of: providing a flip chip having projections of conductive material on one side of the flip chip, the projections having a proximate end attached to the flip chip and a distal end opposite the proximate end; immersing the flip chip in a polymer bath, wherein the polymer bath covers the flip chip and part of the projections up to a point between the proximate end of the projection and the distal end of the projection; removing the flip chip from the polymer bath such that a coating of polymer adheres to the flip chip and the part of the projections covered by the polymer bath to form a coated flip chip having the distal ends of the projections uncoated; and applying ultraviolet light or heat to the coated flip chip such that an outer layer of the coating cures to form a skin-cured coating on the flip chip.
