The influence of crystallographic orientation of the initial substrate of indium phosphide on the formation of porous surface is investigated. An effective mechanism of pore formation is proposed to explain the dependence of the pores shape on the orientation of the original substrate. In the case of the crystallographic orientation of the indium-phosphide substrate (100), pores have near-square shape. For samples obtained on substrates with crystallographic orientation (111), the pores system is complex: the pores are nonuniformly distributed over the surface and have triangular shape.
