Abstract

The invention discloses a double-cavity excimer laser device complete-device frame system. A double-cavity excimer laser device comprises a main oscillation discharging cavity, a power amplification cavity and an optical system relevant to the two cavities. The double-cavity excimer laser device complete-device frame system comprises an installation base (1), a foundational frame (2), an optical system frame (3) and a discharging cavity frame (4), wherein the installation base (1) is a base of the complete-device frame system and used for bearing all components of the complete-device frame system, the foundational frame (2) is directly and fixedly installed on the installation base (1), the optical system frame (3) is used for installation of the optical system and separated from the discharging cavity frame (4), and the discharging cavity frame (4) is installed on the installation base (1) and used for bearing the main oscillation discharging cavity and the power amplification cavity. The double-cavity excimer laser device complete-device frame system can reduce influences of the discharging cavity on the optical system.

Description

technical field [0001] The invention relates to a double-cavity excimer laser frame system, which is suitable for the assembly and integration of the double-cavity excimer laser. Background technique [0002] Excimer laser is a conventional gas laser for ultraviolet characteristic applications. It is currently considered to be the best laser light source for lithography and the main working light source for integrated circuit lithography lithography industry. [0003] Traditional excimer lasers are designed with a single-cavity structure consisting of a single gas discharge module. With the further development of optical lithography technology, laser sources are required to have narrower spectral width (linewidth) and higher power. [0004] In order to narrow the spectral width and increase the laser power at the same time, the dual-cavity structure based on the main oscillator-power amplification technology is introduced into the design of the laser. The basic idea of ​​t...
