Surface Patterning
Plasma can be employed in various ways to facilitate surface patterning, which is often a required processing step for the fabrication of multilayer devices, such as solar cells, sensors, and microfluidic chips. Plasma treatment can enhance surface wettability of substrates and templates to improve pattern transfer during contact printing and self-assembly. Plasma etching can selectively remove polymer thin films and 2D organic materials through a masking layer and can also be used to tune the feature size of polymer templates for fabricating patterned nanostructure arrays. This page provides brief summaries on the application of plasma treatment for surface patterning.
Nitrogen-doped Graphene by Plasma Treatment
Graphene, a single atomic layer of carbon with a hexagonal crystal structure, has been heavily investigated in the past decade for its many unique material properties. With its high electrical and thermal conductivity, near optical transparency,...
Photoresist: Cleaning, Spinning & Descum
To more effectively coat and pattern substrates such as silicon wafers and glass with photoresist, plasma treatment is used extensively to enhance three crucial steps: Cleaning, Spinning and Descum. An essential first task is to ensure that the...
Tissue Culture Plastic (Polystyrene)
Inexpensive, disposable and transparent, plasma treated polystyrene, or tissue culture plastic (TCP), is the most extensively used cell culture material, not only because of its aforementioned qualities but because of its biological affinity....

Plasma Lithography
One common and easily employed method for surface micropatterning is plasma lithography, in which a deformable mask is placed in contact with a substrate surface before plasma treatment to create a chemical template for subsequent processing steps....
