Definitions
- the invention relates to a method for decontamination of microlithography projection exposure systems with optical elements or parts thereof, in particular surfaces of optical elements, with UV light and fluid.
- the invention also relates to a microlithography projection exposure system with a DUV (deep ultraviolet) excimer laser as the light source for the projection exposure. This covers the wavelength range from approx. 100-300 nm with vacuum UV.
- DUV deep ultraviolet
- quartz rods or CaF 2 rods are arranged in lighting devices for semiconductor lenses for thorough mixing of the radiation emitted by a light source. Good total mixing is achieved by multiple total reflection of the light coupled into the glass rod or CaF 2 rod. If the surface of the quartz rod or CaF 2 rod is contaminated, absorption losses occur there as well, resulting in a weakening of the resulting lighting intensity.
- No. 5,024,968 describes a method for cleaning optical components, in particular for X-ray lithography and UV Excimer laser optics are described, high energy radiation with a laser being used as the energy source in connection with a flushing glass which is inert with respect to the surface.
- the cleaning is provided on optical lenses and mirrors as individual components, as is possible, for example, in production.
- the present invention therefore has for its object a process for the decontamination of microlithography projection tion exposure apparatus of the initially mentioned type with which the entire system can be decontaminated in operation or in operation breaks and without the risk of material injury ⁇ conditions of Coatings or materials.
- the inventive use of a second UV light source ⁇ can easily create a decontaminating microlithography projection exposure systems perform.
- the additional UV light source can namely be optimally adapted to the requirements for decontamination without the risk of damage, since it is independent of normal lighting.
- the second light source can also contain the laser used for the exposure or parts thereof.
- it can, for example, be designed to be relatively broadband and, for example, can also be operated with a correspondingly higher output, as is the case for normal lighting.
- the larger bandwidth improves the cleaning effect, since additional narrow-band transitions are stimulated, such as oxygen excitations in the area of the Schumann-Runge band.
- the wavelength can be selected so that problems of material destruction, such as compaction, are minimized. As a rule, the wavelength is close to the exposure wavelength.
- Projection exposure systems have for homogenization of light emitted from the light source a bar-shaped light conductor, is coupled adiation in the radiation emitted by the light source S, which is carried by multiple total reflection at the surface of the light guide, a homogenization of the coupled radiation.
- To absorption losses as a result of contamination of the surface of the light guide is to avoid hen for irradiation thereof vorgese ⁇ a UV light source.
- the UV light source is arranged in a focal point of the ellipsoidal reflector and the radiation emitted by the UV light source is focused on the further focal point in which the light guide is arranged.
- Fig. 1 projection exposure system
- Fig. 2 section through an illumination device.
- a plurality of lenses 2 are arranged in a housing 1.
- the system is equipped with a DUV excimer laser 3 as the light source for the projection exposure.
- a flushing gas supply in the form of a laminar flow is provided at the edge in normal operation, for which purpose a gas supply device 4 is used.
- a further UV light source with a broadband laser 5 is provided.
- the broadband laser 5 serves as a cleaning light source and is coupled into the beam path via a pivotable mirror 6, which is provided with an adjusting mechanism, so that the lenses 2 are illuminated as evenly as possible.
- a partially transparent mirror polarization beam splitter, dichroic mirror
- the arrangement of several light sources between the lenses of the objective for illuminating the surface to be decontaminated can also be provided.
- a gas flow (12) for example gas containing ozone, is generated parallel to the individual surfaces of the lenses 2 or along the lenses 2. Since such a flow would interfere with normal lens operation, it must be able to be switched on and off, although the minimal, diffusion-based gas exchange in normal operation by the gas supply tion device 4 takes place.
- a purge gas supply device 7 is provided, from which the purge gas supply takes place at least approximately perpendicular to the optical axis 10 via lines 8 and radial purge openings in the housing 1.
- purge gas is removed together with contamination constituents via lines 9 in the peripheral wall of the housing 1 on the side opposite the purge openings.
- the radial flushing openings achieve a uniform, directed flow (12) over the lens surfaces.
- the gas supply device 4 can be used for normal operation for purging contamination.
- the gas flow running parallel to the optical axis 10 is e.g. by swiveling mechanical shutters 11 (shown in dashed lines) directed over the lens surfaces. If necessary, the power of the gas supply device 4 must be increased accordingly to increase the flow rate.
- Another possibility of using the purging gas supply in normal operation for contamination purging can also be that cross currents are generated by inhomogeneous magnetic or electrical fields. An alternating use of purge gases of different densities is also possible.
- the gas flow When using the gas supply device 4 for normal operation, the gas flow will be increased so that the laminar flow becomes turbulent. In this case, changes to the lens geometry (frame) may also be necessary to achieve eddy currents.
- the laser 5 intended for decontamination should be a DUV excimer laser that can operate with a bandwidth of 500 pm. It is also possible to use a UV excimer lamp, for example with a wavelength of 222 nm. For example, the exposure laser without injection locking can also be used as a cleaning laser. On the wafer side, a shutter can block the light from entering Prevent exposure breaks.
- FIG. 2 shows an average of a light guide 25 connected downstream of the DUV excimer laser 3 as the light source of the projection exposure system for homogenizing the radiation emitted by the light source.
- a quartz rod is provided as the light guide 25, which is arranged on a focal point 31 of an ellipsoidal reflector 21 surrounding it.
- a CaF 2 rod can also be used as a light guide.
- a UV light source 23 Arranged on the further focal point 29 of the reflector 21 is a UV light source 23 provided for irradiating the surface 27 of the light guide 25, the radiation of which is focused on the surface 27 of the light guide. It can be provided that fluid flows through the reflector.
