Claim:
1. A method for fabricating a semiconductor wafer, the method comprising: transferring a first semiconductor wafer to an implantation chamber; performing an implantation process on the first semiconductor wafer within the implantation chamber; after performing the implantation process on the first semiconductor wafer, transferring the first semiconductor wafer to a single wafer warming chamber while simultaneously transferring a second semiconductor wafer to the implantation chamber; warming the first semiconductor wafer within the single wafer warming chamber, wherein the single wafer warming chamber is outside of the implantation chamber and has a sidewall shared with the implantation chamber; and after performing the warming of the first semiconductor wafer, transferring the first semiconductor wafer to a wafer cassette in a load lock.
