DNS / DAINIPPON 60A is a photoresist equipment used in the field of semiconductor manufacture. Photoresist is an organic film which is sensitive to ultraviolet light and is used to pattern microcircuits and other fine features on semiconductor structures. DNS 60A is a B-type resin system which has superior etching characteristics to other types of photoresist. The unit is composed of an A-type liquid photo-resist, a B-type powder-coated photoresist, and a dark gray developer. The liquid photo-resist is applied by spin coating, and the powder-coated form is sprayed onto the substrate. The dark gray developer is then used to selectively remove the photoresist, which creates patterns in the film which describe the desired structures. DAINIPPON 60A machine is ideal for applications which require high resolution and vertical wall profiles in patterns. The A-type liquid photo-resist can produce features with aspect ratios around 1:1 and fine line widths of 0.2 microns. The B-type powder-coated photoresist is capable of producing wall profiles with aspect ratios higher than 10:1, and line widths down to 0.05 microns. The tool also exhibits good etching resistance, meaning that the features once patterned on the substrate will remain intact during the etching process, resulting in better dimensional accuracy. Additionally, the asset is capable of being patterned at temperatures below boiling point, which is an important factor in semiconductor processing. Overall, 60A photoresist model is a reliable, cost-effective equipment for producing detailed, high resolution patterns. Its excellent wall profile characteristics, etching resistance, and low-temperature patterning capabilities make the system an ideal choice for semiconductor applications.
