10nm pattern generation using thermal scanning probe lithography enabled by simplified materials and processes
Thermal scanning probe lithography (tSPL) has been used to create patterns with sub-20 nm half pitch resolution. Pattern generation uses a thermally sensitive resist and spin coatable hard mask materials to transfer the resist patterns. Spin coatable materials permit users of tSPL to reduce time and cost of the patterning process.

NanoFrazor lithography
Thermal scanning probe lithography (tSPL), also termed NanoFrazor lithography, is based on heated atomic force microscope (AFM) tips to create lithographic patterns by locally evaporating a thermally sensitive resist. This process enables the fabrication of precise 3D patterns and high-resolution structures without the use of charged particles, such as electrons, which have been implicated in substrate damage. Moreover, AFM imaging is exploited for in-situ inspection of the substrate surface before patterning and of the lithographic structures written into the substrate. The immediate visual feedback of the patterning success allows fast turnaround processing which is further enhanced by the absence of proximity effects. tSPL has been pioneered at IBM Research - Zurich over the past ten years and in 2012 an independent company SwissLitho AG was founded to commercialize the technology. A huge number of applications to solve real world nano-physics problems have emerged since then.
Hard-mask pattern transfer
High resolution lithography requires the use of thin (typically 10 nm or even less) resist layers which limits the depth of the tSPL written patterns. For real world applications the depth of these shallow resist patterns needs to be amplified at the device level. A two-step etch-transfer process involving an extremely thin inorganic hard-mask layer and a thicker organic resist mask has been developed for the transfer of high resolution tSPL resist patterns. In a first step the shallow tSPL lithographic pattern is transferred into the inorganic hard-mask by means of reactive ion etching (RIE). SiO2 rich inorganic hard masks with a thickness of only 2-3 nm have been found to be ideal for this process yielding high resolution and low line edge roughness patterns. The thin hard-mask layer is sufficient for the subsequent RIE transfer into the second much thicker organic mask layer. A wide range of carbon based resists compatible with typical industry processes including metal lift-off can be used for the organic mask.
Fabrication of the extremely thin SiO2 rich hard-mask layer in a uniform and pin-hole free manner is absolutely crucial for the whole transfer process to be successful at sub-20 nm half-pitch resolution. The deposition of such thin films of sufficient quality by means of established methods like sputtering or evaporation has been rather challenging. SwissLitho and PiBond have jointly developed a Si hard mask and a process to solve exactly this problem in a user-friendly way that requires only a simple spin coater for the reliable fabrication of the thin inorganic hard mask layer.
Felix Holzner, CEO of SwissLitho, says: "The Si hard mask developed by PiBond is an extremely important step forward, significantly simplifying the hard-mask pattern transfer scheme for our customers."
About SwissLitho
SwissLitho develops, manufactures and sells innovative tools, termed NanoFrazor, for direct write nano-lithography. The principle of operation is based on heated cantilevers and thermally responsive resists. The innovative patterning process enables the fabrication of complex 3D nanostructures with unmatched precision and high density lithography down to sub-10 nm half-pitch resolution. Wet development and vacuum is not needed for this direct write process and samples are not exposed to high-energy electron beams. This novel technology enables easy rapid-prototyping of high-quality nanostructures also on delicate samples for a broad range of nanotechnology applications. The flag ship product "NanoFrazor Explore" was successfully introduced to the market in 2014. In 2017 a table-top entry-level tool "NanoFrazor Scholar" was added to the product portfolio. In addition, SwissLitho continuously develops unique processing know-how to support customers in their applications that often go beyond what is possible by means of conventional nanolithography approaches.
