Latest Patents

Krantz holds a patent for a "Differential detector coupled with defocus for improved phase defect sensitivity." This invention provides apparatus and methods for detecting phase defects by utilizing the distortion of light as it passes through defects in phase shift masks. The technology enhances the signals generated from defects by employing a defocused light inspection beam, which is set to a level above or below the photomask being inspected. The light collected from the photomask is split into at least two portions, each generating a signal. A differential signal produced from these signals is then used to determine the presence of defects in the photomask.
