NanoFrazor Scholar

SwissLitho

The NanoFrazor Scholar is the entry level NanoFrazor system and is particularly suited for academic research groups looking for an easy way to create high-resolution nanopatterns or devices. The NanoFrazor Scholar is a compact system designed to fit in the smallest lab spaces. It can also be installed in a dedicated glovebox to enable nanolithography of sensitive materials in inert conditions.
Like all NanoFrazor tools, the Scholar can pattern features with ultra-high resolution with no need for proximity effect corrections. All the unique NanoFrazor capabilities like in-situ AFM imaging, accurate 3D grayscale lithography, markerless overlay or thermal material conversion are available with the Scholar.
 

Features

Closed-Loop Lithography

Precise markerless overlay and stitching using in-situ AFM

No damage of sensitive materials (no electron or ion beams)

Alternative patterning mode: direct nanoscale thermal conversion

Small footprint

Easy to use (no wet development, no vacuum, etc.)

Unique capabilities help publish in high-impact journals and receive funding for new projects

Applications

The NanoFrazor Explore covers a wide range of applications. Like E-Beam Lithography it is suitable for the fabrication of templates and prototypes of a variety of devices and components at resolutions well below 100 nm.

The NanoFrazor extends the application range of E-Beam significantly. The unique 3D capability with extreme accuracy enables novel devices and components. Furthermore, sensitive materials and devices are not damaged by high energy beam during the NanoFrazor patterning process. This is crucial for the development and improvement of future nanodevices.

Nanooptics: 3D optical elements like spiral phase plates, microlenses or holograms

Optics on the nanometer scale play an important role in fields spanning from fundamental sciences to nanotechnology applications as modern diffractive, refractive or hybrid optics often contain nanoscale patterns. Applications range from micro-lens arrays, polarization filters and Fresnel lenses to compression of ultra-short laser pulses, holograms for quality inspection, security features and advanced astronomical devices.

The NanoFrazor with its unique 3D capabilities is an ideal tool to create arbitrary, smooth and nanometer-resolved surface profiles necessary to enable novel optics applications on the nanometer scale.

Housing

The NanoFrazor Scholar is designed for high robustness and reliability. It is divided into two parts. The table-top patterning module comprises the mechanics which are mounted on a granite table on top of a high-end active vibration isolation table. The second part is a closed 19-inch rack for controllers and electronics, which fits under a table. The compact footprint of the mechanics allows the NanoFrazor Scholar a large degree of flexibility where it is set up, for example it may also be operated inside a glove box.
