Abstract
Description
Technical Field
[0001] This utility model relates to the field of nozzle technology, specifically to a gas uniform disk micro-orifice directional flushing nozzle assembly. Background Technology
[0002] The gas uniform disk micro-orifice directional flushing nozzle assembly is used for precise flushing in wafer processing. It can effectively remove contaminants such as particles and residual chemical liquids generated on the wafer surface during processing, ensuring the cleanliness of the wafer surface and improving the quality of subsequent processing and product yield.
[0003] In the wafer processing rinsing process, it is necessary to uniformly mix different components such as inert gases like nitrogen and argon or specific active gases according to process requirements. However, the existing rinsing gas output often faces the problem of insufficient uniformity, with local areas having excessively high or low gas concentrations, affecting the consistency of cleaning effect, and easily leaving contaminants or damaging the wafer. It is necessary to mix the gases to allow different gases to fully blend and improve uniformity. To this end, we propose a gas uniformity disk micro-hole directional rinsing nozzle group.
