Patent ID: 6897146

Claim:
A method of manufacturing a semiconductor circuit on a substrate, comprising the steps of: providing first and second substrate handling robots; coupling a first process chamber to the first robot so that the first robot can transfer a substrate into and out of the first process chamber, wherein the first process chamber is a deposition chamber or a plasma chamber, and wherein the first process chamber is not coupled to the second robot; coupling a second process chamber to the second robot so that the second robot can transfer a substrate into and out of the second process chamber, wherein the second process chamber is a deposition chamber or a plasma chamber, and wherein the second process chamber is not coupled to the first robot; coupling one or more pass-through chambers to both the first robot and the second robot so that both the first robot and the second robot can transfer a substrate into and out of each of the pass-through chambers, wherein said one or more pass-through chambers include a first pass-through chamber; and subsequently performing the sequential steps of: the first robot transferring a first substrate into the first pass-through chamber; heating said first substrate within the first pass-through chamber; and the second robot removing said first substrate from the first pass-through chamber.
