Thermal scanning probe lithography
Edoardo Albisetti Department of Physics – Polifab Politecnico di Milano via G. Colombo 81, 20133 Milano
First, a brief history of thermally assisted scanning probe lithography (t-SPL)  will be given. Then, the working principle of t-SPL will be introduced, focusing on its main features in terms of capabilities, advantages and limitations compared to other lithographic techniques.
Then, an overview of the applications of t-SPL will be given, focusing on two types of effects induced by the thermal tip, i.e. material removal and direct material conversion. Among this wide range of applications, three specific cases will be discussed into details: first, the 3D nanopatterning of organic resists to be used as masks for the following pattern transfer . Second, the direct material conversion via nanoscale thermochemical reactions , and finally the control of the magnetic properties of thin films via thermally assisted magnetic scanning probe lithography (tam-SPL) .
