Lithography and nanofabrication is used to produce micro and nano scale devices for a wide variety of applications such as biosensors, waveguides, micro electromechanical systems (MEMS) and microfluidics. A combination of lithography, deposition and etching can create all kinds of intricate structures.
We help with designing, patterning and fabricating your devices for rapid prototyping and proof-of-principle development. Our advanced range of lithography and nanofabrication tools can produce anything from thin film transistors to lab-on-a-chip systems.
Electron beam lithography
Overcome the diffraction limit to produce nano-scale features. Small feature sizes maximise substrate use, and often correlate with high power efficiency and high operating frequency for your devices.
Raith Elphy Quantum
- Flexible and affordable solution for rapid prototyping of simple devices using a scanning electron microscope.
- Tungsten (W) filament for patterning features greater than 100 nanometers.
Optical lithography may be used for high-throughput patterning of micro scale structures.
- Full wafer UV illumination through a mask for fast, repeatable exposures.
- Single micron resolution with vacuum contact.
- Direct write optical lithography solution with no need for a mask.
- Single micron resolution with 0.25 micron alignment accuracy for overlaying multiple exposures with previously fabricated structures.
Device fabrication is achieved using a variety of deposition methods capable of processing any material you need. Structures are defined using the lift-off process or etching.
- Magnetron sputtering, both RF and DC.
- Thermal evaporation.
- Reactive ion etching, and deep reactive ion etching.
- Wet etching.
