Claim:
1. A method of making a semiconductor device, comprising: providing a semiconductor wafer including a plurality of semiconductor die comprising bumps formed over contact pads on an active surface of the semiconductor die; depositing an anisotropic conductive film (ACF) over the bumps and active surface of the semiconductor wafer; singulating the semiconductor wafer to separate the semiconductor die; providing a temporary carrier; disposing the semiconductor die with the ACF oriented to the temporary carrier; compressing the ACF under the bumps to form a conductive portion of the ACF electrically connected to the bumps; curing the ACF to form a cured ACF; depositing an encapsulant over the semiconductor die and temporary carrier; removing the temporary carrier to expose the conductive portion of the cured ACF under the bumps; and forming an interconnect structure over the semiconductor die, cured ACF, and encapsulant with the interconnect structure being electrically connected through the conductive portion of the cured ACF to the bumps.
