%X Using semiclassical approximation method, the fermion tunnels at cosmological horizon of higher dimensional de Sitter and Schwarzschild de Sitter space-times are researched in this paper. In our work, the Dirac equation, which describes the property of 1/2 spin particles, is simplified, and then the semiclassical Hamilton-Jacobi equation is obtained via the condition that there are non-trivial solutions of Dirac equation. The research has been simplified greatly, and the Hawking temperature and tunneling rate at cosmological horizon of static higher dimensional de Sitter space time is gotten finally.
