minClearanceOverLayer

Sets the minimum clearance between layer1 and layer2 shapes where the space between the two is completely filled by layer3 shapes. For example, minClearanceOverLayer can be used to set the required clearance between implant (layer1) and gate (layer2) over diffusion (layer3), while minClearance specifies the minimum clearance between all other layer1 and layer2 shapes.
