An alternative technique is proposed to create microscopic atom traps loaded with atoms from a gravito-optical surface trap (GOT), which is composed of an evanescent-wave mirror and a vertically aligned hollow laser beam. Our trap design is based on the use of current-carrying transparent conductors and transparent permanent magnets fabricated on the surface of a glass prism in the form of an internal structure of a refractive-index-matched thin dielectric film. The conductors can be fabricated of indium tin oxide (ITO) and the magnets of yttrium iron garnet (YIG). Different kinds of traps may be envisaged: i) spin-independent electro-optical ii) magneto-optical for either high- or low-field seeking atoms, and iii) purely magnetic for atoms in the low-field seeking states. In case iii), the magnetic-field minimum is located far enough from the film surface to make the contribution of the optical field negligible.
