Abstract

PURPOSE:To enable multiple kinds of photoresists to be coated by means of using only one nozzle in common by a method wherein one nozzle is connected in parallel with multiple photoresist feeding pipes while cleaning pipes are provided to feed the nozzle with solvent and drying gas for photoresists through a running together part of respective photoresist feeding pipes and the nozzle. CONSTITUTION:In order to change the coating state of one photoresist 5a to that of the other photoresist 5b, firstly a pump P1 is stopped from driving to stop feeding the photoresist 5a and then solvent 3a is jetted from pipes 4a, 4b to clean up the inside of a nozzle 1. When the photoresist nozzle 1 is completely washed up, gas 3b such as N2 is fed from the pipes 4a, 4b to dry up the inside of nozzle 1. Finally, another pump P2 is driven to feed the other photoresist 5b to the nozzle 1.

[Problems to be Solved by the Invention] When applying photoresist with various types of film using one coating machine as described above, conventionally one nozzle was required for one type of photoresist. Previously, several nozzles were placed close together or the nozzles were replaced. However, in the method of placing several nozzles close together, all the nozzles must be adjusted so that they drop the photoresist onto the center of the semiconductor wafer, and this limits the number of nozzles that can be arranged. There are some drawbacks such as storage. Furthermore, the method of replacing nozzles has the disadvantage that the nozzles must be replaced each time the type of photoresist to be coated changes.

[Difference between the invention and the prior art 1 When coating many types of photoresists using one coating machine, the present invention differs from the above-mentioned conventional apparatus in which one nozzle is used for one type of photoresist. When changing the type of photoresist applied from the first photoresist to the second photoresist, the inside of the nozzle is cleaned by jetting a solvent into the nozzle to remove the first photoresist, and then the second photoresist is applied. It has an original content that allows photoresist to be applied with the same nozzle.

[Effects of the Invention] As described above, the present invention can greatly simplify nozzle position adjustment by applying various types of resists with one nozzle. Furthermore, even if the type of photoresist changes, the dropping position does not change, so coating defects can be prevented and photoresist can be saved. Furthermore, since there is only one nozzle, there is no need to replace the nozzle when changing the type of resist.
