Abstract:
A method for improving an interface of a semiconductor device, the method comprising:providing a first semiconductor substrate and second semiconductor substrate having a first layer formed thereon, wherein the first layer further comprises an oxidized region; establishing a first loading position in a first process chamber; consecutively inserting the first substrate and the second substrate into the first process chamber when the first process chamber is in the first loading position; establishing a first processing position in the first process chamber after consecutively inserting the first substrate and the second substrate; generally simultaneously processing the first substrate and the second substrate, wherein the oxidized region is chemically reduced by exposure to a first plasma; establishing the first loading position in the first process chamber after the first substrate and the second substrate are generally simultaneously processed; consecutively removing the first substrate and the second substrate from the first process chamber; establishing a second loading position in the second process chamber; inserting the first substrate into the second process chamber after the first substrate and the second substrate are removed from the first process chamber; establishing a second processing position in the second process chamber after the first substrate is inserted; processing the first substrate, wherein a second layer is formed over the first layer by exposure to a second plasma; establishing the second loading position in the second process chamber after the first substrate is processed; inserting the second substrate into the second process chamber after the first substrate is processed; establishing the second processing position in the second process chamber after the second substrate is inserted; generally simultaneously processing the first substrate and second substrate, wherein the second layer is formed over the first layer by exposure to the second plasma; establishing the second loading position in the second process chamber after the first substrate and second substrate are generally simultaneously processed; removing the first substrate from the second process chamber after the first substrate and second substrate are generally simultaneously processed; establishing the second processing position in the second process chamber after the first substrate is removed; processing the second substrate after the first substrate is removed, wherein the second layer is formed over the first layer by exposure to the second plasma; establishing the second loading position in the second process chamber after the first substrate is removed and the second substrate is processed; and removing the second substrate from the second process chamber.
