BACKGROUND OF THE INVENTION

With the high integration of a semiconductor device, the number of connection pads for connecting a semiconductor chip on which a semiconductor integrated circuit is formed to an external circuit increases. Thus, the number of lead lines of a semiconductor package that is mounted on a printed circuit board (PCB) significantly increases.

As the number of the lead lines increases, packaging technologies to which a lead frame is applied according to a related art are difficult to be applied to a highly-integrated semiconductor chip including about 500 pins or more.

Thus, ball grid array (BGA) package technologies as new concepts in which output terminals of a semiconductor package are disposed by using a wide lower surface of the semiconductor package are being developed.

In the BGA package technologies, a semiconductor chip is mounted on a PCB, and a solder ball is disposed to correspond to an output terminal of the PCB. Also, an integrated circuit of a semiconductor package is electrically connected to an external circuit of an electrical device through the output terminal of the PCB and the solder ball connected to the output terminal.

Here, the solder ball is disposed on a surface opposite to the PCB on which the semiconductor integrated circuit is mounted. Also, a soldering process for electrically connecting the solder ball to the output terminal of the PCB is required.

Here, an apparatus for soldering the semiconductor chip to a surface of the PCB at a predetermined temperature to cure the soldered portion after the semiconductor chip is mounted on the surface of the PCB may be called a reflow apparatus.

In the reflow apparatus, the PCB on which the solder ball is placed is put in a heating furnace to heat the solder ball for a predetermined time at a predetermined temperature. As a result, the solder ball may be soldered to the output terminal of the PCB.

In general, fluxes may be generated in a reflow process. Also, impurities may be introduced into a substrate treating apparatus. Due to the fluxes and impurities, a substrate treating process including the reflow process may be deteriorated in reliability. In addition, a time required for performing the substrate treating process may increase to reduce process efficiency.

Hereinafter, a substrate treating method including a reflow treating method using the substrate treating apparatus according to an embodiment of the present invention will be described.

The substrate treating method according to an embodiment of the present invention includes a loading process in which a substrate to which a solder bump is attached is loaded from a load port into a substrate transfer module, a cleaning process in which the substrate and the solder bump are cleaned within a cleaning unit, a reflow process which is performed on the substrate in a substrate treating module, and an unloading process in which the substrate is transferred into the load port.

The cleaning process may include a primary cleaning process in which the substrate and the solder bump are cleaned before the reflow process and a secondary cleaning process in which the substrate and the solder bump are cleaned after the reflow process. Also, the cleaning process includes a first cleaning process in which a first fluid for cleaning the substrate is supplied onto the substrate and a second cleaning process in which a second fluid for drying the substrate is supplied onto the substrate.

In general, the substrate cleaning process in the substrate treating process for performing the reflow process may be performed by using a separate apparatus. However, according to an embodiment of the present invention, the cleaning process and the reflow treating process may be performed within one substrate treating apparatus. Thus, a time required for performing the substrate treating process including the reflow treating process may be reduced to improve process efficiency. Also, it may prevent efficiency of the substrate treating process from being reduced by impurities and fluxes.

The reflow process may be performed while the substrate on which the primary cleaning process is performed is successively transferred from a first process chamber to a fifth process chamber. Here, in the first to fourth process chambers, the substrate and the solder bump may be heated. Also, in the fifth process chamber, the substrate and the solder bump may be heated or cooled. The heating process and the reflow process may be performed on the substrate and the solder bump within each of the process chambers while the substrate moves from the first process chamber to the fourth process chamber. Thereafter, the substrate is cooled within the fifth process chamber. The substrate passing through the first to fifth process chambers to completely perform the reflow process is transferred to the outside of the reflow treating unit.

The secondary cleaning process is performed on the substrate on which the reflow treating process is performed. In the secondary cleaning process, the fluxes and impurities that are mainly generated in the reflow process are removed. The substrate on which the secondary cleaning process is performed is transferred into the substrate transfer module.

According to the embodiment of the present invention, the time required for the reflow treating process may be reduced to improve efficiency of the substrate treating process.

The feature of the present invention is not limited to the aforesaid, but other features not described herein will be clearly understood by those skilled in the art from this specification and the accompanying drawings.
