By a News Reporter-Staff News Editor at Science Letter -- Research findings on Scientific Instruments are discussed in a new report. According to news reporting originating in Piscataway, New Jersey, by NewsRx journalists, research stated, "In this paper, we present a high-speed direct pattern fabrication on hard materials (e.g., a tungsten-coated quartz substrate) via mechanical plowing. Compared to other probe-based nanolithography techniques based on chemical-and/or physical-reactions (e.g., the Dip-pen technique), mechanical plowing is meritorious for its low cost, ease of process control, and capability of working with a wide variety of materials beyond conductive and/or soft materials."
The news reporters obtained a quote from the research from the State University of New Jersey, "However, direct patterning on hard material faces two daunting challenges. First, the patterning throughput is ultimately hindered by the 'writing' (plowing) speed, which, in turn, is limited by the adverse effects that can be excited/induced during high-speed, and/or large-range plowing, including the vibrational dynamics of the actuation system (the piezoelectric actuator, the cantilever, and the mechanical fixture connecting the cantilever to the actuator), the dynamic cross-axis coupling between different axes of motion, and the hysteresis and the drift effects related to the piezoelectric actuators. Secondly, it is very challenging to directly pattern on ultra-hard materials via plowing. Even with a diamond probe, the line depth of the pattern via continuous plowing on ultra-hard materials such as tungsten, is still rather small (
According to the news reporters, the research concluded: "A fine pattern of the word 'NANO' is also fabricated at the speed of ~5 mm/s."
