Abstract

Sensor zones are created on an inner pod of a reticle container using a dry coating method. The sensor zones are discrete zones having a specific spectral reflectivity. The sensor zones are positioned such that they can be read by a tool to determine distance of portions of the pod. The use of discrete zones and a dry coating method for applying those discrete zones overcomes issues with inconsistency and difficulty in cleaning or maintaining reflectance of an inner pod of the reticle container in comparison with inner pods plated entirely with material or other wet coating applied materials.
