Extreme ultraviolet lithography (also known as EUV or EUVL) is a next-generation lithography technology using an extreme ultraviolet (EUV) wavelength, currently expected to be 13.5nm. EUV is currently being developed for possible future use in combination with immersion lithography at 32nm pitch resolution, sometimes referred to as the 7 nm node. The primary EUV tool maker, ASML, projects EUV at 5nm node to require a higher numerical aperture than currently available and multiple patterning to a greater degree than immersion lithography at 20nm node. Immersion lithography is still more than 4 times faster than EUV (275 WPH vs. 65 WPH as detailed below), due to source power limitations; hence, multiple patterning with immersion lithography has already been used where EUV had previously been expected to be used.
While source power is the chief concern due to its impact on productivity, significant changes in EUV mask infrastructure, including blanks, pellicles and inspection, are also under study. Particle contamination would be prohibitive if pellicles were not stable above 200 W, i.e., the targeted power for manufacturing. Without pellicles, particle adders would reduce yield, which has not been an issue for conventional optical lithography with 193nm light and pellicles. The current lack of any suitable pellicle material, aggravated by the use of hydrogen plasma cleaning in the EUV scanner, is preventing the adoption of EUV lithography for volume production.
In air, EUV is the most highly absorbed component of the electromagnetic spectrum, requiring high vacuum for transmission.
EUV generation
Neutral atoms or condensed matter cannot emit EUV radiation. Ionization must take place first. EUV light can only be emitted by electrons which are bound to multicharged positive ions; for example, to remove an electron from a +3 charged carbon ion (three electrons already removed) requires about 65 eV. Such electrons are more tightly bound than typical valence electrons. The existence of multicharged positive ions is only possible in a hot dense plasma. Alternatively, the free electrons and ions may be generated temporarily and instantaneously by the intense electric field of a very-high-harmonic laser beam. The electrons accelerate as they return to the parent ion, releasing higher energy photons at diminished intensities, which may be in the EUV range. If the released photons constitute ionizing radiation, they will also ionize the atoms of the harmonic-generating medium, depleting the sources of higher-harmonic generation. The freed electrons escape since the electric field of the EUV light is not intense enough to drive the electrons to higher harmonics, while the parent ions are no longer as easily ionized as the originally neutral atoms. Hence, the processes of EUV generation and absorption (ionization) strongly compete against each other.
