Wet anisotropic etching for fluidic 1D nanochannels [PDF]

open access: yesJournal of Micromechanics and Microengineering, 2003
In this paper a method is proposed to fabricate channels for fluidic applications with a depth in the nanometer range. The channels with smooth and straight sidewalls are constructed with the help of micromachining technology by etching shallow trenches into <100> silicon using native oxide as a mask material and OPD ressist developer as the ...

Wetting of anisotropic sinusoidal surfaces - experimental and numerical study of directional spreading [PDF]

open access: yes, 2014
Directional wettability, i.e. variation of wetting properties depending on the surface orientation, can be achieved by anisotropic surface texturing. A new high precision process can produce homogeneous sinusoidal surfaces (in particular parallel grooves)
