Abstract:
A method for generating an electromagnetic radiation includes the following operations. A target material is introduced in a chamber. A light beam is irradiated on the target material in the chamber to generate plasma and an electromagnetic radiation. The electromagnetic radiation is collected with an optical device. A gas mixture is introduced in the chamber. The gas mixture includes a first buffer gas reactive to the target material, and a second buffer gas to slow down debris of the target material and/or plasma by-product, so as to increase an reaction efficiency of the target material and the first buffer gas, and to reduce deposition of the debris of the target material and/or the plasma by-product on the optical device.

Claim (Index 1):
A method for generating an electromagnetic radiation, comprising:\n introducing a target material in a chamber; irradiating a light beam on the target material in the chamber to generate plasma and an electromagnetic radiation; collecting the electromagnetic radiation with an optical device; and introducing a gas mixture in the chamber through a gas outlet in communication with an aperture of the optical device, wherein the gas outlet extends into the optical device through the aperture, the gas mixture comprises a first buffer gas reactive to the target material, and a second buffer gas to slow down debris of the target material and/or plasma by-product, so as to increase an reaction efficiency of the target material and the first buffer gas, and to reduce deposition of the debris of the target material and/or the plasma by-product on the optical device, the first buffer gas comprises hydrogen gas, the second buffer gas comprises xenon gas, and an amount ratio of the second buffer gas to the first buffer gas is less than 1.
