Abstract
Cut spacer reference marks, targets having such cut spacer reference marks, and methods of making the same by forming spacer gratings around grating lines on a first layer, and fabricating an angled template mask that extends across and resides at an angle with respect to such spacer gratings. Angled, cut spacer gratings are etched into a second layer using the angled template mask to superimpose at least a portion of the spacer gratings of the first layer into the second layer.
