Abstract

An extreme UV light generation device with pre-shaped and enhanced target source comprises a vacuum cavity (1), a target source generator (2), a target source pre-shaped enhancer, a high energy generator (7), an energy injector (8), an extreme UV light collector (11) and a residual target material collector (13). The target source pre-shaped enhancer comprises a target source motion track controller (4), a target source shaper (5), a target source detector (14), an extreme UV light and / or plasma detector (15) and a synchronous controller (16), wherein the synchronous controller (16) is used for controlling the target source generator (2), the target source motion track controller (4), the target source shaper (5), the high energy generator (7) and the energy injector (8) according to monitoring data of the target source detector (14) and the extreme UV light and / or plasma detector (15), so as to achieve the goal of optimizing output energy of extreme UV light. Using the extreme UV light generation device, the problem of low energy conversion efficiency of the existing UV light generation device can be solved, and the output energy of the extreme UV light of the device can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an extreme ultraviolet light generating device. Background technique [0002] As the semiconductor industry has higher and higher requirements for the integration of integrated circuits (IC, Integrated Circuits), traditional visible light or near-ultraviolet lithography machines can no longer meet the needs of industry development, and the market needs lithography equipment with better performance to maintain the overall The rapid development momentum of the industry. It is well known that the lithographic resolution is inversely proportional to the numerical aperture of the projection objective and directly proportional to the exposure wavelength. Therefore, in order to improve the resolution of lithography, the next-generation lithography machine will use shorter wavelength EUV (Extreme Ultraviolet, extreme ultraviolet, especially extreme ultraviolet with a wavelength o...
