Patent ID: 8536715

Claim:
A semiconductor device, comprising: a semiconductor chip including a protruding connection electrode which protrudes from an element surface thereof: an insulating layer covering a back surface and side surfaces of the semiconductor chip, and extended from an upper part of the side surfaces of the semiconductor chip to a periphery of the semiconductor chip, wherein the element surface of the semiconductor chip retreats from a surface of the insulating layer, and a space is formed on the element surface side of the semiconductor chip; a resin substrate formed under the insulating layer, and sealing a periphery and a back surface side of the semiconductor chip; an interlayer insulating layer formed on the semiconductor chip and the insulating layer such that the space is filled by the interlayer insulating layer; a via hole that is formed in the interlayer insulating layer and reaches the connection electrode of the semiconductor chip; and a wiring layer formed on the interlayer insulating layer, and directly connected to the connection electrode through the via hole; wherein the resin substrate contacts the insulating layer, and surface of the interlayer insulating layer, except the via hole, is flat.
