Latest Patents

Karawajczyk holds a patent for a "Long sweep length DUV microlithographic beam scanning acousto-optical deflector and optics design." This technology utilizes extreme beam shaping to maximize the energy projected through an acousto-optical deflector (AOD). The patent describes the use of first and second expanders positioned before and after the AOD. In one implementation, the optical path shapes energy from a source, such as a Gaussian laser spot, deflects it, and then reshapes it into a writing spot. In another implementation for image capture, the disclosed optics reshape a reading spot from an imaged surface to a high-aspect ratio beam at the AOD exit, which is subject to deflection by the AOD. The optics also reshape the radiation relayed by the high-aspect ratio beam through the AOD to a detector. This dual functionality allows for both projection and metrology applications.
