Ceramic (e.g. semiconducting TiO2, or insulating ZrO2, Al2O3) nanopatterns on various substrates (e.g. Si,
Au, SiO2, Cr) have been prepared through simple fast, cheap, reproducible, and easy to scale up “bottom-up”
approach, involving chemical solution deposition, self-assembly via commercial block copolymers, and
thermal treatment.[1] The patterns is composed of hexagonally arranged nanoperforations through which the
surface of the substrate remains accessible. The typical thickness of the patterns can be controlled between 5
and 20 nm, while a proper selection of chemical and processing conditions allows to perfectly adjust the
motif dimension between 10 and 100 nm.[2] They constitute novel highly ordered heterogeneous
Inorganic/inorganic Nano Patterned (INP) substrates, which present a unique combination of thermal,
mechanical, and chemical stability with the very interesting characteristics of the ordered nano-heterogeneity
associated to the accessibility of the substrate surface through the perforations.

perforations;[3] FePt nanoparticles co-electrochemically generated inside the INP‟s perforations;[4] CoPt percolated media deposited by MBE onto
the INP;[5] and Ge nanoparticles elaborated by Solid dewetting onto the INP.
In the present contribution, we will first describe how this novel generation of substrates is prepared and how
one can perfectly control the morphology and the dimensions of the nanoperforation motifs. We will then
show how the ordered topography and chemical heterogeneity can be utilised to direct the distribution of
deposited materials. Several examples, gathering chemical and physical deposition processes as shown in
Figure 1, will be reported as illustration and demonstration.
