Abstract:
PURPOSE: A semiconductor chip and a method for forming a semiconductor chip are provided to uniformly maintain the thickness of a semiconductor chip by etching the back side of a semiconductor chip by using an insulating layer included in the substrate as an etch stopping layer. CONSTITUTION: A semiconductor layer(105) has an active surface(10) and an non-active layer(20) which face each other. A first inter layer dielectric layer(110) is formed on the active surface of the semiconductor layer. An insulating layer(103) is arranged on the non-active layer of the semiconductor layer. A through hole(115) successively passes through the first inter layer dielectric layer, the semiconductor layer, and the insulating layer. A spacer(125) is interposed between the inner wall of the hole and a through electrode.

PURPOSE: A wave soldering apparatus having buoyancy force applying means, a soldering method, and a method for forming a flip chip solder bump are provided to form a solder bump which is capable of being used a flip chip by applying buoyancy to a melting solder. CONSTITUTION: In a wave soldering apparatus having buoyancy force applying means, a soldering method, and a method for forming a flip chip solder bump, a solder bath(110) maintains a molten solder(112) by an optimal temperature. A substrate is arranged on the top of the solder bass. A nozzle(124) ejects molten solder to the bottom of a substrate passing the upper part of the solder bath. A pump(134) is adjacent to the bottom of the nozzle. The solder bath is divided into an upstream domain(110a) and a downstream domain.

Abstract:
The present invention is to provide a double side adhesive tape having a first adhesive layer on the upper side of a carrier and a second adhesive layers on the first adhesive layer. The first adhesive layer of the double side adhesive tape touches the carrier. The second adhesive tape of the double side adhesive tape touches the active surfaces of semiconductor chips on the second adhesive tape. The first adhesive layer is separated from the second adhesive layer. The second adhesive layer remains on the active surfaces of the semiconductor chip. A first opening is formed to selectively expose the active surfaces of the semiconductor chip by patterning the second adhesive layer. A first conductive component filling the first opening is formed on the second adhesive layer.

PURPOSE: A method for fabricating a fan-out wafer level package and the package formed by the method are provided to stack semiconductor chips by using an accommodating part having a cavity, and to prevent the collapse of a semiconductor chip. CONSTITUTION: An accommodating part(CR) where a cavity(CV) is formed is prepared. A separation layer(IL) is formed in the upper surface of the accommodating part in a conformal manner. A first semiconductor chip(CP1) is arranged in the cavity. At least one second semiconductor chip(CP2) is arranged on the first semiconductor chip. A mold layer(MD) for covering the second semiconductor chip is formed. The separation layer is removed to isolate the accommodating part from the first semiconductor chip.
