Abstract: The method of growing GaAs on a porous silicon substrate includes the steps of forming a porous layer(2) on a silicon substrate(1) containing impurities, and trimethyl gallium and AsH3 gas are alternately sprayed to the porous layer(2) on the silicon substrate(1) using ALE and UHVCVD apparatuses, thereby forming a GaAs thin film(3) which is an epitaxial layer.

Abstract: The surface stabilizing method of a porous silicon substrate is characterized by forming a porous layer on the other side of the silicon substrate doped with an impurity and formed with a positive electrode on the one side of the substrate, (b) removing the positive electrode, (c) spraying a trimethyl gallium and an arsine gas to the other side of the substrate at 400˜500deg. C, and (d) depositing a surface stabilizing layer of gallium arsenic(GaAs) compound on the other side of the substrate by the automatic layer epitaxy(ALE) process.
