Spraying Photo Resistive Coatings |
Photoresist coatings are used for both electronic device and microelectromechanical (MEMs) device production. Photoresists are typically polymeric materials that are either enhanced (i.e. via cross-linking, negative photoresist materials) or solubilized (positive photoresist materials) via exposure to light, hence light is used to pattern photoresist coatings on substrates, a technique known as photolithography. Resist-coated substrates are then exposed to particular solvent(s) or solution(s), known as developers, to remove unwanted resist material, often in preparation for etching and/or the application of other functional material(s) to a substrate. |
