Abstract:
A method for generating EUV radiation is provided. The method includes generating a target droplet with a target droplet generator. The method further includes recording an image of the target droplet on a first image plane to detect a first position of the target droplet. The method also includes recording an image of the target droplet on a second image plane to detect a second position of the target droplet. In addition, the method includes projecting a laser pulse onto the target droplet when the target droplet is located on a focus plane. The method further includes adjusting at least one parameter of the target droplet generator according to the first position and the second position.

Claim (Index 1):
A radiation source module, comprising:\n a target droplet generator configured to generate a target droplet along an x-axis direction; a first laser source configured to generate a first laser pulse to extend the target droplet; a second laser source configured to generate a second laser pulse that heats the target droplet to produce plasma emitting EUV radiation; a first camera configured to generate an image of the target droplet at a first image plane which is perpendicular to the x-axis direction and parallel to a y-z plane; a second camera configured to generate an image of the target droplet at a second image plane which is perpendicular to the x-axis direction and parallel to the y-z plane, the second image plane being different from the first image plane, wherein the first image plane and the second image plane are arranged along the x-axis direction and located between the target droplet generator and the first laser source; and a controller configured to: determine a position of the target droplet at the first image plane based on the image captured by the first camera; determine a position of the target droplet at the second image plane based on the image captured by the second camera; and adjust at least one parameter of the target droplet generator based on a set of data, wherein the set of data comprises a difference between the position of the target droplet at the first image and the position of the target droplet at the second image.
