Abstract

A method of inspection or metrology of four sides of a sample is disclosed. The method includes providing samples in a carrier at a first side of an imaging tool and moving the samples from the carrier to the imaging tool via a pick-and-place stage assembly. The method includes imaging first and second sides of the samples via first and second channels of the imaging tool and returning the samples to the carrier. The method includes rotating the carrier by 90 degrees and translating the carrier to an opposite side of the imaging tool and moving the samples individually from the carrier to the imaging tool. The method includes imaging a third and fourth side of the sample via the first and second channel of the imaging tool and returning the one or more samples from the imaging tool to the carrier.
