The present invention provides a process for producing a rare earth metal-based permanent magnet having, on its surface, a corrosion-resistant film containing inorganic fine particles having a specific average particle size and dispersed in a film phase formed from a silicon compound. In a heat treatment for forming a film by a hydrolyzing reaction and a thermally decomposing reaction of the silicon compound, followed by a polymerizing reaction, a stress is generated within the film by the shrinkage of the film. In the corrosion-resistant film formed by the producing process according to the present invention, however, such stress is dispersed by the presence of the inorganic fine particles and hence, the generation of physical defects such as cracks is inhibited. In addition, voids between the adjacent inorganic fine particles are filled with the film phase formed from the silicon compound and hence, the formed film is dense. Further, no alkali ions are contained in the film and hence, the film itself is excellent in corrosion resistance. Yet further, the film has an excellent close adhesion to the magnet achieved by an excellent reactivity with the surface of the magnet.

The invention discloses a method suitable for laminating a film for an ultrathin wafer, which is characterized in that when film lamination is carried out, a certain pressure is supplied to push a wafer to a thin film so as to adhere the thin film and the wafer together. In the method and the device suitable for laminating the film for the ultrathin wafer, provided by the invention, pressure is applied to the wafer so as to enable the wafer to be adhered to the thin film. The wafer and the thin film can be firmly adhered together through the pressure applied to the wafer. When film lamination is carried out, the thin film can supply supporting force to the wafer so as to prevent the wafer from cracking due to excessive deformation. Therefore, by using the method and the device provided by the invention for laminating the film, the problem that the ultrathin wafer cracks can be effectively avoided.

The invention relates to a preparation method of a doped anthracene organic compound thin film and application thereof. The novel conducting anthracene compound doping suitable for PCBM ([6,6]-phenyl-C61-butyric acid methyl ester) is introduced; ABMG has high conductivity, so that the mixed concentration of the ABMG in the PCBM can reach 10 percent to 15 percent, and the electron transmission performance of the PCBM is reduced; a formed PCBM film after the mixing with the ABMG is smoother; the coverage is more complete. The ABMG with high film forming performance and high conductivity is mixed in a conventional electron transmission layer material of PCBM; the electron transmission layer thin film with high flatness and complete coverage is obtained. Meanwhile, the thin film technology is applied onto perovskite solar batteries, so that the voltage of the solar battery, the filling factor and the conversion efficiency are all improved; the repeatability and the efficiency uniformity of multiple batches of solar batteries are also improved.
