The application belongs to the technical field of medicine, and particularly relates to a composition for alleviating and repairing testicular damage caused by heat stress and application thereof. The composition for alleviating and repairing testicular damage caused by heat stress comprises the following raw materials: lycopene inclusion compound, ginsenoside Re, modified chitosan nanoparticles and a solvent. The amount of the modified chitosan nanoparticles is 10-15 wt% of the ginsenoside Re. The application innovatively designs a combination formula with lycopene and ginsenoside Re as the core. Both of the two main effective components in the formula are natural plant or traditional Chinese medicine extract, which effectively avoids the conflict between the medicinal properties of traditional Chinese medicines and has good biological safety. The composition can significantly repair the testicular damage caused by heat stress and accelerate the recovery after heat stress damage.

A method for removing a low-dielectric-constant material layer includes: providing a wafer to be cleaned, the surface of which has a low-dielectric-constant material layer; dry etching the wafer using oxygen plasma to reduce the methyl content in the low-dielectric-constant material layer; performing a first isotropic etching on the wafer for a first duration using an etching solution of a first concentration; and performing a second isotropic etching on the wafer for a second duration using the etching solution of a second concentration; wherein the second concentration is less than the first concentration, and the second duration is less than the first duration. This method can quickly and effectively remove the low-dielectric-constant material layer from the wafer surface and significantly reduce the number of particles on the cleaned wafer surface, making the wafer suitable for reuse, thereby improving efficiency and reducing costs.
