Provided is an apparatus for performing a reflow process of a solder ball provided to a semiconductor chip. The reflow apparatus may include a coil, a support member and a moving member. The coil may receive a current from a power supply to heat the solder ball using an induced heating method. The support member may be disposed on the front or the rear of the coil and may support a printed circuit board on which a semiconductor chip is mounted. The moving member may move the printed circuit board so that the printed circuit object passes through an internal space surrounded by the coil.

An apparatus to package a semiconductor chip includes a coil configured to use induction heating to reflow a solder ball of the semiconductor chip. The coil includes a first body, a second body parallel to the first body, a third body extending from the first body to the second body. The first and second bodies are symmetrical with respect to a vertical plane disposed therebetween. The first and second bodies have inclined surfaces facing each other, and the inclined surfaces are distant from each other downward.

A void that is created in a conductive electrode in a through hole that extends through an integrated circuit substrate can be used as a joining interface. For example, an integrated circuit structure includes an integrated circuit substrate having a conductive pad on a first face thereof, and a through hole that extends through the integrated circuit substrate from a second face of the integrated circuit substrate that is opposite to the first face and through the pad. A conductive electrode is provided in the through hole that extends from the second face to the first face through and onto the pad. The conductive electrode includes a void therein adjacent the second face. The void includes a void opening adjacent the second face that defines inner walls of the conductive electrode. A conductive material is provided in the void that directly contacts the inner walls of the conductive electrode. Related fabrication methods are also disclosed.

An apparatus and a method for providing a character deletion function is provided. A plurality of deletion items having respective designated deletion schemes are displayed, when there is a request for a deletion mode while inputting characters. It is determined if a Drag event occurs after a Press event occurs in an area where one of the plurality of deletion items is displayed. It is determined if a Release event occurs when the Drag event occurs. A deletion function in a deletion scheme corresponding to a deletion item having an area where the Release event occurs is performed when the Release event occurs. Accordingly, a user has convenience with which, when inputting characters, the user receives various deletion schemes and can perform a desired deletion function in a simple way.
