<p>An apparatus and method for gas-phase bromine trifluoride (BrF3) silicon isotropic room temperature etching system for both bulk and surface micromachining. The gas-phase BrF3 can be applied in a pulse mode and in a continuous flow mode. The etching rate in pulse mode is dependent on gas concentration, reaction pressure, pulse duration, pattern opening area and effective surface area.</p> |
