DNS / DAINIPPON 80A is a negative photoresist equipment developed by DNS Screen Manufacturing Company. It is composed of two components - the photo-active polymer resin and an organic solvent. The resin functions as a photo-initiator, activating when exposed to light and transforming its morphology from a low molecular weight, viscous liquid to a higher molecular weight, solid form. This high molecular weight form acts as a barrier to subsequent etch processing, protecting areas from further etching. The organic solvent used in the system is also key to its performance. It facilitates the solubility of the resin and helps to reduce the viscosity of the solution, making it easier for the developer to deposit and move. Furthermore, the solvent also serves as a vehicle to transport the active photoresin components between the developer and resist characteristics. DNS 80A is specifically designed for photofabrication/etching of thin film, metallized surfaces. It is composed of two films, the photoresist film and an adherent layer below it. The photoresist film is a negative photoresist composed of an organic polymer and an organic solvent. In exposure to deep ultraviolet light (DUV) or electron beam radiation, the photosensitive polymers change their solubility from insoluble to soluble, transforming from viscous liquid films to solid films. An etchant, such as an aqueous solution of potassium iodide and potassium bromide, is then used to selectively remove the exposed resist interior and underlying material. In addition to the high resolution image capabilities and enhanced adhesion of the photoresist unit, DAINIPPON 80A also offers a high degree of thermal stability. This feature is further improved through the addition of an additional layer of an adhesion promoter, which allows higher process temperatures as needed. This results in a preferred machine when working with metallization on chip-on-board or organic board substrate assemblies, where higher temperatures may be required. In conclusion, 80A photoresist tool is a powerful and reliable asset for photofabrication/etching of thin film, metallized substrates. By providing high resolution images, thermal stability, and enhanced adhesion properties, it is well suited for advanced applications within the semiconductor industry.
