Epitaxial growth rate varying method for side surface of semiconductor pattern

摘要

An improved epitaxial growth rate varying method for a side surface of a semiconductor pattern capable of controlling a growth rate of a side surface of a semiconductor pattern by controlling the amount of CCl4 gas supplied when forming an epitaxial layer on a patterned GaAs substrate in a metalorganic chemical deposition method, thus fabricating a desired quantum wire, and which is characterized by controlling a side-surface growth rate of an epitaxial layer in accordance with the CCl4 doping gas flow rate while an epitaxial layer is formed on a patterned GaAs substrate in a metalorganic chemical deposition method and in achieving a desired substantial flatness.
