Say I have a schottky diode with n type semiconductor. Why cant electrons from the metal flow to the valance band of the semiconductor?

If I reverse bias the schottky diode, the valance band may be higher than the fermi level at the contact, and electrons should be able to flow from metal to the semiconductor. Consequently the reverse saturation current should increase. Could anyone explain?
