Scanning probe lithography

From Wikipedia, the free encyclopedia

Scanning probe lithography[1] (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.[2] 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.[3]

Classification

[edit]

The different approaches towards SPL can be classified by their goal to either add or remove material, by the general nature of the process either chemical or physical, or according to the driving mechanisms of the probe-surface interaction used in the patterning process: mechanical, thermal, diffusive and electrical.

Overview

[edit]

Mechanical/thermo-mechanical

[edit]

Mechanical scanning probe lithography (m-SPL) is a nanomachining or nano-scratching[4] top-down approach without the application of heat.[5] Thermo-mechanical SPL applies heat together with a mechanical force, e.g. indenting of polymers in the Millipede memory.

Thermal

[edit]

Thermal scanning probe lithography (t-SPL) uses a heatable scanning probe in order to efficiently remove material from a surface without the application of significant mechanical forces. The patterning depth can be controlled to create high-resolution 3D structures.[6][7]

Thermo-chemical

[edit]

Thermochemical scanning probe lithography (tc-SPL) or thermochemical nanolithography (TCNL) employs the scanning probe tips to induce thermally activated chemical reactions to change the chemical functionality or the phase of surfaces. Such thermally activated reactions have been shown in proteins,[8] organic semiconductors,[9] electroluminescent conjugated polymers,[10] and nanoribbon resistors.[11] Furthermore, deprotection of functional groups[12] (sometimes involving a temperature gradients[13]), reduction of oxides,[14] and the crystallization of piezoelectric/ferroelectric ceramics[15] has been demonstrated.

Dip-pen/thermal dip-pen

[edit]

Dip-pen scanning probe lithography (dp-SPL) or dip-pen nanolithography (DPN) is a scanning probe lithography technique based on diffusion, where the tip is employed to create patterns on a range of substances by deposition of a variety of liquid inks.[16][17][18] Thermal dip-pen scanning probe lithography or thermal dip-pen nanolithography (TDPN) extends the usable inks to solids, which can be deposited in their liquid form when the probes are pre-heated.[19][20][21]

Oxidation

[edit]

Oxidation scanning probe lithography (o-SPL), also called local oxidation nanolithography (LON), scanning probe oxidation, nano-oxidation, local anodic oxidation, AFM oxidation lithography is based on the spatial confinement of an oxidation reaction.[22][23]

Bias induced

[edit]

Bias-induced scanning probe lithography (b-SPL) uses the high electrical fields created at the apex of a probe tip when voltages are applied between tip and sample to facilitate and confining a variety of chemical reactions to decompose gases[24] or liquids[2][25] in order to locally deposit and grow materials on surfaces.

Current induced

[edit]

In current induced scanning probe lithography (c-SPL) in addition to the high electrical fields of b-SPL, also a focused electron current which emanates from the SPM tip is used to create nanopatterns, e.g. in polymers[26] and molecular glasses.[27]

Magnetic

[edit]

Various scanning probe techniques have been developed to write magnetization patterns into ferromagnetic structures which are often described as magnetic SPL techniques. Thermally-assisted magnetic scanning probe lithography (tam-SPL)[28] operates by employing a heatable scanning probe to locally heat and cool regions of an exchange-biased ferromagnetic layer in the presence of an external magnetic field. This causes a shift in the hysteresis loop of exposed regions, pinning the magnetization in a different orientation compared to unexposed regions. The pinned regions become stable even in the presence of external fields after cooling, allowing arbitrary nanopatterns to be written into the magnetization of the ferromagnetic layer.

In arrays of interacting ferromagnetic nano-islands such as artificial spin ice, scanning probe techniques have been used to write arbitrary magnetic patterns by locally reversing the magnetization of individual islands. Topological defect-driven magnetic writing (TMW)[29] uses the dipolar field of a magnetized scanning probe to induce topological defects in the magnetization field of individual ferromagnetic islands. These topological defects interact with the island edges and annihilate, leaving the magnetization reversed. Another way of writing such magnetic patterns is field-assisted magnetic force microscopy patterning,[30] where an external magnetic field a little below the switching field of the nano-islands is applied and a magnetized scanning probe is used to locally raise the field strength above that required to reverse the magnetization of selected islands.

In magnetic systems where interfacial Dzyaloshinskii–Moriya interactions stabilize magnetic textures known as magnetic skyrmions, scanning-probe magnetic nanolithography has been employed for the direct writing of skyrmions and skyrmion lattices.[31][32]

Comparison to other lithographic techniques

[edit]

Being a serial technology, SPL is inherently slower than e.g. photolithography or nanoimprint lithography, while parallelization as required for mass-fabrication is considered a large systems engineering effort (see also Millipede memory). As for resolution, SPL methods bypass the optical diffraction limit due to their use of scanning probes compared with photolithographic methods. Some probes have integrated in-situ metrology capabilities, allowing for feedback control during the write process.[33] SPL works under ambient atmospheric conditions, without the need for ultra high vacuum (UHV), unlike e-beam or EUV lithography.
