Surfing Scanning Probe Nanolithography at Meters Per Second

Area of Science:

• Nanotechnology
• Materials Science
• Manufacturing Engineering

Background:

• Scanning probe lithography (SPL) offers maskless, high-resolution patterning at low cost.
• Conventional SPL methods suffer from very low throughput due to limited scanning speeds.

Purpose of the Study:

• To develop a high-speed, probe-based method for continuous nanoscale patterning.
• To overcome the throughput limitations of traditional SPL techniques.

Main Methods:

• Utilized ultrafast electron-induced deposition within a nanoscale flow for direct writing.
• Achieved linear scanning velocities of meters per second with a 20 MHz patterning frequency.
• Employed self-adaptive hydro- and aerodynamics for precise probe control and microfluidic precursor delivery.

Main Results:

• Demonstrated direct writing of nanoscale patterns at unprecedented speeds.
• Successfully controlled fast scan motion using advanced aerodynamic and hydrodynamic functions.
• Showcased the potential for enhanced throughput with parallel probe configurations.

Conclusions:

• This low-cost, maskless patterning approach significantly increases nanomanufacturing throughput.
• Opens new possibilities for developing high-throughput nanomanufacturing techniques.
• Paves the way for scalable and efficient nanoscale fabrication.
