A method for controlling metal impurities on the surface of a silicon wafer
ActiveCN112614789BSemiconductor/solid-state device testing/measurementMaterial analysis by electric/magnetic meansChemical physicsMetal impurities
The present invention relates to a method for controlling metal impurities on the surface of silicon wafers. The method comprises the following steps: providing a silicon wafer; performing a wetting treatment by spraying ultrapure water on the silicon wafer to fully wet the surface of the silicon wafer; drying the silicon wafer with a fully wetted surface; repeating the steps of the wetting treatment and the drying treatment; performing an acid solution treatment by treating the surface of the silicon wafer with an acid solution to obtain a treatment solution; performing an analysis treatment by using ICPMS to analyze the metal ion content in the treatment solution; and a judgment step of comparing the detected metal ion content with a metal pollution lower limit value to judge whether the ultrapure water can continue to clean the silicon wafer. Thus, through this method, the pollution amount of metal ions in the ultrapure water to the silicon wafer can be detected, the relative influence of the increase or decrease of the metal content on the surface of the silicon wafer by the metal ions in the ultrapure water can be determined, and this method also has the advantages of simple operation and high accuracy rate.

Substrate processing apparatus and substrate processing method
The substrate is held in place by suction with sufficient force to withstand its rotation while being processed with the processing solution. [Solution] In this invention, the suction area of the chuck body is surrounded by an annular elastic portion of the packing. Before the center of the lower surface of the substrate and the suction area of the chuck body come into contact, the annular elastic portion deforms to follow the lower surface of the substrate while surrounding the center of the lower surface of the substrate, and adheres tightly. As a result, suction leakage is less likely to occur, and the substrate is held in place by the suction area not only when there is no warping, but also when there is warping.

A flat membrane type evaporation crystallization integrated machine
This utility model discloses a planar film-type evaporation and crystallization integrated machine, belonging to the technical field of evaporation and crystallization equipment. It includes: a stirring tank with a lid on top; an evaporation chamber on one side of the stirring tank; multiple sets of planar evaporation films inside the evaporation chamber; and a stirring assembly inside the stirring tank, comprising bevel gear one, bevel gear two, and bevel gear three. This assembly can stir the solution from different directions and angles, enabling faster and more comprehensive mixing of the solvent and solution, ensuring uniform solute distribution in the solution, providing a stable material basis for subsequent evaporation and crystallization, reducing localized crystallization or differences in crystal quality caused by uneven solution distribution, and allowing for quick installation and removal of the lid. Operators can directly and thoroughly clean the inside of the stirring tank, preventing residual crystals or impurities from affecting subsequent solution processing.
