Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor manufacturing-related products, specifically a wet cleaning device for semiconductor manufacturing. Background Technology
[0002] A wafer refers to a silicon wafer used to fabricate silicon semiconductor circuits. The semiconductor integrated circuit (IC) manufacturing process requires the participation of both organic and inorganic materials. Furthermore, the manufacturing process is always carried out in a cleanroom with human intervention, inevitably leading to various environmental contaminations of the silicon wafers. Therefore, wafers need to be cleaned to remove contaminants. Semiconductor wet cleaning equipment uses a rinsing method for cleaning.
[0003] However, existing cleaning devices have defects because the spray water impacts the semiconductor wafer during rinsing, causing the spray water to splash and making it impossible to effectively collect the spray water. In addition, the cleaning process is not very stable. Utility Model Content

[0032] The working principle of this wet cleaning device for semiconductor production is described in detail below: First, the semiconductor wafer is placed on the placement plate 6. The rotating sleeve 14 moves down and pushes the stop plate 13. The stop plate 13 uses the upright plate 15 to pull the traction sleeve 7 down.
