Reticle and methods for forming a device or reticle are presented. A reticle is provided with a device pattern and a first monitoring pattern. The first monitoring pattern includes a plurality of first test cells having a first test cell area and a first test pattern. The first test cells have different first pitch ratios to an anchor pitch and the first test pattern fills the first test cell area of a first test cell. A wafer with a resist layer is exposed with a lithographic system using the reticle. The resist is developed to form a patterned resist layer on the wafer and the wafer is processed using the patterned resist layer.
