Patent ID: 7997851

Claim:
A method of processing a substrate, comprising: positioning two substrates within a load lock chamber body, wherein the substrates are positioned within first and second chambers that are within the load lock chamber body, wherein the first and second chambers lie in a laterally spaced relation, and wherein the load lock chamber body is coupled with an integrated processing tool; removing the substrates from the load lock chamber body and positioning the substrates in the integrated processing tool; processing the substrates; re-positioning the substrates within the load lock chamber body, wherein the substrates are positioned within third and fourth chambers that are within the load lock chamber body, wherein the third and fourth chambers lie in a laterally spaced relation and at an elevation above the first and second chambers, and wherein the first, second, third, and fourth chambers are environmentally isolated from each other during processing; and monitoring conditions of the substrates within the first, second, third, and fourth chambers, wherein the monitoring comprises monitoring the conditions through transmissive chamber lids.
