Title: Surface treatment of glass substrate
Inventor: YONE KIYOE
IPC: C03C23/00
Filed: 1991-11-25
Abstract: PURPOSE:To prevent the deterioration in properties of a coupling agent film formed in order to enhance the adhesion of a photoresist layer to a glass substrate at the time of forming a glass master disk for an optical disk. CONSTITUTION:An aq. coupling agent soln. is applied on a glass substrate in a stage S2 after foreign matter, such as particulate, is removed by prewashing the glass substrate in a stage S1. The excess coupling agent is removed by executing the post washing of the glass substrate in a stage S3. The glass substrate is pulled up from the liquid held at a low temp. and is dried in a stage S4. Since the drying is executed at the low temp., the deterioration in the properties of the coupling agent film is prevented. The coupling agent film is subjected to a baking treatment in a stage S5 and a photoresist layer is formed thereon in a stage S6. Since there is no deterioration in the properties of the coupling agent film, the photoresist film securely and tightly adheres to the coupling agent film. Finally, the photoresist layer is subjected to exposing and development processing in a stage S7, by which the glass master disk for the optical disk is formed.
