Many of the methods we have described are
based on AFM technology, which currently suffers
from low throughput. Work is being done to increase
the scan speed using high-bandwidth mechanics16
and by predistorting the drive for a step and
settle response faster than the mechanical
resonant frequency of the cantilevers would suggest.
Another effort to increase throughput is by creating parallel arrays of AFM tips, which have already
reached as many as 11 million tips for DPN
systems.
