Abstract: A silicon wafer with an array of integrated circuit (IC) dies formed on the wafer is provided with a protective coat applied to a surface of the wafer to protect the IC dies from debris created during a laser scribing process. The IC dies can include die bumps that can be adversely affected by debris from the laser scribing process. The protective coat is a tape or a film that may be optically transparent, chemically non-reactive to the laser energy and formed of material that can be ablated by the laser scribing. The protective coat is removed from the IC dies after laser scribing leaving the IC dies and die bumps clean of any debris, thereby decreasing the number of defective dies.

An encapsulant is injected into a space defined between surfaces of the mold piece and the microelectronic die. The encapsulant includes a liquid phase epoxy and a solid phase catalyst compound when injected. The encapsulant mixture is heated in the space to a temperature where the catalyst compound becomes a liquid and cures the epoxy. The catalyst compound may, for example, be polystyrene and the catalyst may be diphenyl phosphine. The catalyst compound is then heated to above its glass transition temperature so that the diphenyl phosphine is released from the polystyrene. The diphenyl phosphine then cures the epoxy. The epoxy is preferably a liquid at room temperature.
