Abstract:
An optical inspection system that utilizes sub-200 nm incident light beam to inspect a surface of an object for defects is described. The sub-200 nm incident light beam is generated by combining first light having a wavelength of about 1109 nm with second light having a wavelength of approximately 234 nm. An optical system includes optical components configured to direct the incident light beam to a surface of the object, and image relay optics are configured to collect and relay at least two channels of light to a sensor, where at least one channel includes light reflected from the object, and at least one channel includes light transmitted through the object. The sensor is configured to simultaneously detect both the reflected and transmitted light. A laser for generating the sub-200 nm incident light beam includes a fundamental laser, two or more harmonic generators, a frequency doubler and a two frequency mixing stages.

Claim (Index 9):
A laser for generating sub-200 nm wavelength light, the laser comprising:\n a fundamental laser configured to generate a fundamental wavelength; a generator configured to generate first light having a wavelength of approximately 1109 nm; a second harmonic generator configured to generate a second harmonic from the fundamental wavelength; a frequency doubler configured to generate a fourth harmonic from the second harmonic; a first frequency mixing stage  428  configured to convert the fourth harmonic into second light having a wavelength of approximately 234 nm; and a second frequency mixing stage configured to combine said first light at said wavelength of approximately 1109 nm with said second light at said wavelength of approximately 234 nm to generate said sub-200 nm wavelength light at a wavelength between 190 nm and 200 nm.
