Abstract

Scanning probe lithography (SPL) includes a variety of techniques which produce nanopatterns based on the interaction between an AFM probe and a substrate, Figure 1 shows an overview of possible techniques of scanning probe lithography. Here we focus on thermal SPL where a heated probe is used to remove or transform material of the substrate. Advantages such as the use under ambient conditions, large throughput even at high resolution, single step processing and the possibility of closed-loop lithography make scanning probe lithography very competitive in the field of nano-fabrication (1). In t-SPL the temperature at the apex is an important quantity in studying the behavior of different materials under fast exposure to heat. Due to heat losses and a limited heat transport from the heater to the apex, the temperature at the tip is not a priori known. To measure the temperature at a scale of

Scanning probe lithography

Scanning probe lithography (SPL) describes a set of nanolithographic methods to pattern material on the nanoscale using scanning probes. It is a direct-write, mask-less approach which bypasses the diffraction limit and can reach resolutions below 10 nm. It is considered an alternative lithographic technology often used in academic and research environments. The term scanning probe lithography was coined after the first patterning experiments with scanning probe microscopes (SPM) in the late 1980s.

Scanning probe microscopy

Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope, an instrument for imaging surfaces at the atomic level. The first successful scanning tunneling microscope experiment was done by Gerd Binnig and Heinrich Rohrer. The key to their success was using a feedback loop to regulate gap distance between the sample and the probe.

Heat transfer

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species (mass transfer in the form of advection), either cold or hot, to achieve heat transfer.
