Abstract: A conformal boron doping method for a three-dimensional structure includes the steps of: removing a natural oxide layer on a surface of a silicon-based three-dimensional substrate; forming a buffer layer on the surface of the silicon-based three-dimensional substrate; forming a boron oxide thin film on the alumina buffer layer; covering a passivation layer on a surface of the boron oxide thin film; and driving boron impurities containing boron oxide into the silicon-based three-dimensional substrate through the buffer layer by using laser or rapid annealing, to dope the silicon-based three-dimensional substrate. Selecting suitable boron source precursors and oxidants solves the problems of difficult nucleation and inability to form a film after reaching a certain thickness for boron oxide. By selecting alumina as the passivation layer, it is possible to protect the boron oxide thin film from being damaged, and thus achieve damage-free diffusion doping during laser or rapid annealing processes.

Abstract: This invention provides a rocking chair comprising a rear support frame arranged with a rotating part, a front rocking frame pivoted to the rear support frame and used as a front support frame, and an electric rocking drive mechanism driving the front rocking frame to continuously rock back and forth relative to the rear support frame; when the front rocking frame continuously rocks back and forth relative to the rear support frame, the distance between the moving part and the rotating part is alternatively decreased and increased to lift and lower pivoting point of the rear support frame and the front rocking frame relative to support surface. The rocking chair has automatic rocking and lifting function, and no additional fixing frame is necessary. The power requirement is low. When the moving part and the rotating part are wheels, the rocking chair can also be used as a stroller.
