Patent ID: 8883607

Claim:
A method comprising: supporting a substrate on a substrate support, wherein the substrate is disposed under a reactor assembly, the reactor assembly comprising a plurality of reactors, wherein each of the plurality of reactors comprises a reactor wall having a wall thickness, wherein each of the plurality of reactors comprises a reactor region within the reactor walls; defining a first plurality of site isolated regions on the substrate, wherein the first plurality of site isolated regions are distributed substantially evenly over the substrate, wherein the first plurality of site isolated regions comprises a first processed area which corresponds to the reactor region and which is smaller than the area of the first plurality of site isolated regions by the wall thickness; defining a second plurality of site isolated regions on the substrate, wherein the second plurality of site isolated regions are distributed substantially evenly over the substrate, wherein the second plurality of site isolated regions comprises a second processed area which corresponds to the reactor region and which is smaller than the area of the second plurality of site isolated regions by the wall thickness; wherein at least one site isolated region of the first plurality of site isolated regions partially overlaps at least one site isolated region of the second plurality of site isolated regions; positioning the reactor assembly over the substrate to form the first plurality of site isolated regions; processing the first processed area of the first plurality of site isolated regions on the surface of the substrate in a combinatorial manner using at least one reactor; moving the substrate with respect to the reactor assembly to position the reactor assembly over the substrate to form the second plurality of site isolated regions, wherein the substrate is moved a distance so that the first and second processed areas are contiguous; and processing the second processed area of the second plurality of site isolated regions on the surface of the substrate in a combinatorial manner using at least one reactor.
