In this work we analyzed the localization of fermions of spin-1/2 in a D-dimensional bulk in a (D-2)-branes scenario. The model used for this is a dimensional extension of models Randall-Sundrum (RS) and thick branes. It is known as co-dimension 1 model. The obtained results are based in no-factorizable geometry type Anti-de Sitter. During the zero mode localization process, it is uses both the Randall-Sundrum metric as a metric with smooth warped factor that depends on the coordinate of extra dimension, frequently used in thick brane models. As the spin-1/2 representations change with dimension of spacetime, the localization process, somehow, must take into account the dimensionality of bulk. Based on these models, one finds that the localization fermions in (D-2)-branes changes when the spacetime is par or odd. They are not located when the dimensionality of bulk is par an only one of chiralities can be located when D is odd.
