    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.

    Abstract: 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.
