    摘要: A developer suitable for use with positive photoresists is based on a buffered aqueous-alkaline solution containing non-ionic surfactants and contains in the solution 1-100 ppm of the surfactants, preferably of the ethoxylated-alkylphenol type. The resultant photoresist shows outstanding properties with respect to the resolution and edge sharpness obtainable in the developed resist image and with respect to its developing activity, developing capacity and stability.
