Classification: CPC H | IPC H

Claim 7:
8. The apparatus of claim 1, wherein the substrate exhibits a first anisotropic curvature along a first main surface before the implant pattern is generated, the first anisotropic curvature comprising a first difference between a first substrate bowing along a first direction and a second substrate bowing along a second direction, perpendicular to the first direction, and
wherein the substrate exhibits a second anisotropic curvature after the implant pattern is generated, the second anisotropic curvature comprising a second difference between a third substrate bowing along the first direction and a fourth substrate bowing along the second direction, the second anisotropic curvature being less than the first anisotropic curvature.
