Title: Method for developing optical master disk
Inventor: KOMATA HIROSHI
IPC: B05D1/40
Filed: 1989-03-09
Abstract: PURPOSE:To prevent the occurrence of a stain near the center hole in a substrate by washing the substrate under rotation while feeding washing water rom the center hole. CONSTITUTION:When an optical master disks 1 with an exposed photoresist layer is developed, washed and dried under rotation, washing water is fed from a feed hole 6 pierced in the center of a turntable 2. A developing soln. does not accumulate in the center hole in the substrate of the master 1 and the occurrence of a stain can be prevented. Since no washing water is sprayed on the substrate, a developing chamber 3 and a drying air nozzle 9 are not contaminated by splashes and a master disk nearly free from defects can be formed.
