摘要:
A semiconductor manufacturing apparatus includes a load port supporting a FOUP holding a plurality of wafers, a process module performing a semiconductor manufacturing process on the plurality of wafers, an equipment front end module disposed between the load port and the process module, providing a clean area, and including an opener for opening and closing a door of the FOUP, a transfer module sequentially transferring the plurality of wafers between the FOUP and the process module, and a purge module spraying a purge gas toward the plurality of wafers in the FOUP when the door is open to connect the equipment front end module and the FOUP, so as to make gases released from the plurality of wafers be recovered into the equipment front end module.
摘要:
A substrate processing apparatus for processing substrates prevents the substrates from contaminating as they are transferred. The apparatus includes a container, like a FOUP, for containing substrates, at least one processing chamber where the substrates are processed, a substrate transferring module including a substrate transfer chamber and at least one load port for supporting a container, and a contamination controlling system for the substrate transfer chamber. The contamination controlling system includes a purge gas supply inlet connected to the substrate transfer chamber, and a gas circulating tube for recycling the purging gas to circulate through the chamber. The substrate transfer chamber is purged using the purging gas to remove moisture and contaminating materials from the substrate transfer chamber. The formation of particles on the substrate otherwise caused by a reaction between the moisture and contaminating materials while the substrate is standing by in the container can be prevented.
摘要:
An improved wafer transfer apparatus is provided that allows the ambient atmosphere within a modified front open unified pod (“FOUP”) while the FOUP is positioned on a loading stage provided on an equipment front end module (“EFEM”). In particular, the wafer transfer apparatus includes both an injection assembly and an exhaust assembly that will be engaged when the door of the FOUP is docked to a door holder provided on the EFEM. The injection assembly may include a mass flow controller (“MFC”) for controlling the injection of purge gas(es) into the container. Similarly, the exhaust assembly may include a MFC for controlling the removal of fluid from the container. While the door is docked to the door holder, inert or less reactive gases may be introduced into the container, thereby reducing the likelihood of oxidation or contamination of the wafers therein.
