Semiconductor chip and semiconductor package with planar surfaces recess structure and lower dielectric isolation

Abstract

A semiconductor package is provided. The semiconductor package includes, a base structure including a body, an upper pad on the body, and an upper insulating layer on a side surface of the upper pad, the base structure having a planar upper surface provided by the upper insulating layer and the upper pad; and a semiconductor chip on the planar upper surface of the base structure, and including a substrate, a wiring structure below the substrate, a low dielectric layer on a side surface of the wiring structure, a lower connection pad below the wiring structure, and a lower insulating layer on a side surface of the lower connection pad, the semiconductor chip having a planar lower surface provided by the lower insulating layer and the lower connection pad, a side surface provided by the lower insulating layer and the substrate, and a recess surface extending from one end of the side surface to one end of the planar lower surface, wherein the low dielectric layer is spaced apart from the recess surface of the semiconductor chip by the lower insulating layer.
