Abstract: A semiconductor wafer has a plurality of semiconductor die separated by a saw street. The wafer is mounted to dicing tape. The wafer is singulated through the saw street to expose side surfaces of the semiconductor die. An ESD protection layer is formed over the semiconductor die and around the exposed side surfaces of the semiconductor die. The ESD protection layer can be a metal layer, encapsulant film, conductive polymer, conductive ink, or insulating layer covered by a metal layer. The ESD protection layer is singulated between the semiconductor die. The semiconductor die covered by the ESD protection layer are mounted to a temporary carrier. An encapsulant is deposited over the ESD protection layer covering the semiconductor die. The carrier is removed. An interconnect structure is formed over the semiconductor die and encapsulant. The ESD protection layer is electrically connected to the interconnect structure to provide an ESD path.

Abstract: A semiconductor device has a semiconductor die with an encapsulant deposited over and around the semiconductor die. An interconnect structure is formed over a first surface of the encapsulant. An opening is formed from a second surface of the encapsulant to the first surface of the encapsulant to expose a surface of the interconnect structure. A bump is formed recessed within the opening and disposed over the surface of the interconnect structure. A semiconductor package is provided. The semiconductor package is disposed over the second surface of the encapsulant and electrically connected to the bump. A plurality of interconnect structures is formed over the semiconductor package to electrically connect the semiconductor package to the bump. The semiconductor package includes a memory device. The semiconductor device includes a height less than 1 millimeter. The opening includes a tapered sidewall formed by laser direct ablation.
