Provided is a semiconductor package including a substrate, a first semiconductor chip disposed on the substrate to have a rectangular shape with long and short sides, and a second semiconductor chip disposed on the first semiconductor chip to have a rectangular shape with long and short sides. Centers of the first and second semiconductor chips may be located at substantially the same position as that of the substrate, and the long side of the first semiconductor chip may be substantially parallel to a diagonal line of the substrate. Further, the long side of the second semiconductor chip may be not parallel to that of the first semiconductor chip.

Semiconductor packages

Provided are a semiconductor package and a method of fabricating the same. The semiconductor package includes a semiconductor chip having a bonding pad, a metal line electrically connected to the semiconductor chip and having a terminal contacting an external terminal, an insulation layer covering the metal line and having an opening that defines the terminal, and a molding layer molding the semiconductor chip, wherein the molding layer includes a recess pattern exposing the bonding pad and extending from the bonding pad to the terminal, and the metal line is embedded in the recess pattern to contact the bonding pad.

Semiconductor packages and methods of fabricating the same

A reflow method of a solder ball provided to a treatment object may include providing a coil, applying a current to the coil, and moving the treatment object through an internal space surrounded by the coil.

Reflow method

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.

Coil and semiconductor apparatus having the same

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.

Reflow apparatus, reflow method, and package apparatus

An assembling apparatus includes a chip transfer unit, a heating unit, a testing unit, and an output unit. The chip transfer unit mounts first semiconductor chip to a circuit board to form an electrical circuit. The heating unit heats a solder connection to electrically connect the semiconductor chip to the circuit board. The testing unit tests the semiconductor chip, and, when the testing unit determines that the first semiconductor chip is not functioning properly, the heating unit reheats the solder connection to remove the non-functioning semiconductor chip from the circuit board.
