Description

technical field [0001] The invention relates to a preparation method of an organic and inorganic rare earth nano composite film, in particular to a preparation method of an aminosilane-rare earth nano film on the surface of a single crystal silicon wafer. It belongs to the technical field of film preparation. Background technique [0002] With the advancement of high technology, the machinery manufacturing industry is developing in the direction of miniaturization, which involves the tribological problems of the surface of micro-machines. Due to the advantages of high hardness, low cost and small surface roughness of silicon material, the application in MEMS has been paid more and more attention. However, silicon materials without surface treatment are highly brittle, and surface cracks are prone to delamination wear and brittle fracture under low tensile stress, which is difficult to meet the requirements of use. Therefore, surface modification technology is required to im...
