Poly-N-vinylamid-modifizierte Elektrode als Komponente eines spektroelektrochemischen Sensors für Catecholderivate
… carbon, graphite, indium tin oxide) using the spin-coating method. The copolymer adhered well to all tested materials. The resulting films were water-insoluble, flexible, colourless and thin. The film thickness was 400 – 700 nm. From the tested catechol derivatives, caffeic acid proved to be an …

Modeling and analysis of extrusion-spin coating : an efficient and deterministic photoresist coating method in microlithography
… a variation of 5 [angstroms] for advanced chips. Spin coating is the prevalent coating method to produce the required thickness and uniformity, but it typically wastes over 90% of the photoresist applied. A more efficient method needs to be developed for two reasons. The first is that 80% of the …
