Product Description
"advantages:
Technology: We use high precision photoresist coating process, make the photoresist coating process strictly control in manageable, so as to avoid the coating defects, using nanoscale lithography process, through the application of photoresist equipment adjustment, solved the out-of-focus problem under the level 1 um lithography, so that the image size control in the scope of regulation, to ensure the uniformity of the graphics is consistent, high efficiency, high precision etching technique. By dry etching process of the ICP etching equipment, the cylindrical photoresist mask etching for conical best graphics, so as to achieve the nanoscale etching, and solved the wafer etching uniformity and conical graphic size deviation, etc.
