Latest Patents

Ajgaonkar's latest patents include a multi-channel light source for projection optics heating. This invention provides systems, apparatuses, and methods for heating a plurality of optical components. The method involves receiving an input radiation beam from a radiation source and generating multiple output radiation beams based on this input. These beams are then transmitted towards heater head optics designed to heat the optical components. Additionally, the method allows for controlling the power value and achieving a flat-top far-field profile for each output beam.

Another significant patent involves a lithographic apparatus that includes an illumination system, a projection system, a temperature-sensitive object, and a temperature sensor. This sensor features a detector and waveguide device that is thermally coupled to the temperature-sensitive object. The illumination system illuminates a pattern of a patterning device, while the projection system projects an image of this pattern onto a substrate. The temperature sensor plays a crucial role in measuring temperature variations through its scattering features, which reflect different spectra based on temperature changes.
