摘要:
A combination nozzle for applying a developer material and a washing solution material at different time intervals to a photoresist material layer disposed on a wafer is provided. The combination nozzle includes a number of developer nozzle tips connected to a developer supply line and a number of washing solution nozzle tips connected to a washing solution supply line. The developer supply line and the washing solution supply line ensure that the developer material and the washing solution material are always substantially isolated from one another. Furthermore, the developer nozzle tips and the washing solution nozzle tips are arranged so that developer material and washing solution material do not come into contact with one another. The volume of the material and the volume flow of the material can be controlled by electronically controlled valves.
