This letter reports the design, fabrication, and testing of a multifunctional scanning probe array for nanoscale imaging and patterning. The probe array consists of multiple cantilever probes, with each probe being able to perform a dedicated function such as scanning probe lithography (e.g., dip pen nanolithography and scanning probe contact printing) or scanning probe microscopy (e.g., atomic force microscopy and lateral force microscopy). The bending states of each probe can be controlled by using an integrated thermal electric actuator so that it is possible to engage any individual probe(s) independently for writing or imaging purposes. The multifunctional probe array is therefore capable of performing a rich variety of operations with minimal chemical crosstalk and high registration accuracy. It will eliminate the need for probe chip exchanges and increase the operational efficiency. The probe tips in a given array may be made of different materials. Further, the tip and cantilever may be made of different materials for a given probe. In this work, we focus on the development of a probe array consisting of dip pen nanolithography probes, scanning probe contact printing probes (of various tip sizes), and scanning probe microscopy probes.
