PURPOSE: A semiconductor chip, a semiconductor package and a manufacturing method of the semiconductor chip are provided to improve contact reliability of a conductive pad and a penetrating electrode by connecting the penetrating electrode to the conductive pad through a multilayer line pattern. CONSTITUTION: A semiconductor substrate(105) has a first surface(106) and a second surface(107). An integrated circuit layer(110) is located on the first surface of the semiconductor substrate. An interlayer insulating layer(120) is located on the integrated circuit layer. A penetrating electrode(140) passes through the semiconductor substrate and the interlayer insulating layer, and is exposed from the second surface of the semiconductor substrate. A multilayer line pattern(153) is connected to the penetrating electrode, and is located on the interlayer insulating layer. An inter-metallic insulating layer(145) covers the multilayer line pattern. A conductive pad(160) is formed on the inter-metallic insulating layer, and is connected to the penetrating electrode through the multilayer line pattern.
Abstract:
An interconnection structure of a semiconductor package is provided to more simplify the fabricating process of an interconnection structure by forming a contact hole for exposing an interconnection on a photoresist pattern without removing a preliminary photoresist structure from a conductive pattern such that the preliminary photoresist structure is disposed on the conductive pattern to form a conductive pattern connected to a pad. A pad(110) inputs a signal to a circuit part(105) or outputs a signal from the circuit part, disposed on a body(102) with the circuit part. A conductive pattern(120) is disposed on the upper surface of the body, electrically connected to the pad. An insulating photoresist structure(130) is formed on the upper surface of the conductive pattern, having a contact hole for exposing a part of the upper surface of the conductive pattern. The insulating photoresist structure has substantially the same outer shape as the conductive pattern.
