    • A system for detecting a void in a photoresist layer can include: a detector, a processor, and a memory. The detector can be arranged to receive reflected light from a surface of a sample. The processor can be in electrical communication with the detector. The memory can store instructions that, when executed by the processor, can cause the processor to perform operations. The operations can comprise: receiving optical data from the detector, receiving calibrated data, and determining an existence of the void. the optical data can include information regarding a signature of the reflected light. The calibrated data can include information regarding a signature for a known sample of photoresist. The determination of the existence of the void can be based on a deviation of the optical data from the calibrated data.
