Abstract

The invention relates to the field of semiconductor photolithography and provides an automatic cleaning device for an exhaust duct, the automatic cleaning device is arranged on the exhaust duct of a gluing and developing cabinet, the exhaust duct is a bent pipe formed by connecting a first pipe and a second pipe, the first pipe is communicated with a gluing chamber in the gluing and developing cabinet, the automatic cleaning device for an exhaust duct includes a nozzle externally connected with a cleaning solvent source and a fluid drain pipe, the nozzle is arranged on the inner wall of the first pipe, and the fluid drain pipe is connected with the lower part of the first pipe and communicated with the first pipe. The invention further provides a gluing and developing cabinet, including a washer bearing table arranged inside the gluing chamber and an exhaust duct communicated with the gluing chamber, the exhaust duct is provided with the automatic cleaning device for an exhaust duct. Via the nozzle, cleaning solvent can be sprayed to the first pipe of the exhaust duct, on which photo-resist dust particles are accumulated easily, in order to timely clean photo-resist dust particles accumulated on the inner wall of the exhaust duct without dismounting the exhaust duct.

Description

technical field [0001] The invention relates to the field of semiconductor photolithography, in particular to an automatic cleaning device for an exhaust pipe and a glue-coating and developing machine. Background technique [0002] The rubber coating and developing machine in the process of semiconductor lithography, its structure is as follows figure 1 As shown, it includes a gluing chamber 10, a wafer carrier 11 and an exhaust duct 12, the wafer carrier 11 is arranged inside the gluing chamber 10, and a wafer is placed on the wafer carrier 11, at present, the exhaust pipe 12 is an elbow composed of a vertical pipe 121 and a horizontal pipe 122 connected to each other, and the vertical pipe 121 communicates with the glue chamber 10 for Discharge the gas in the gluing chamber. During the gluing process, the gluing and developing machine uses a high-speed rotating motor to drive the wafer carrier 11 to rotate. During this process, about 80% of the photoresist will be thrown ...
