Title: Pretreatment method for iii-v compound semiconductor epitaxial growth onto si
Inventor: KIKUTA KUNIKO
IPC: C30B29/40
Filed: 1988-09-14
Abstract: PURPOSE:To prevent oxidation at the surface of Si and to enable group III-V epitaxial growth onto Si to be done without preparing a large-scale ultrahigh vacuum device by removing a natural oxide film from the surface of Si by H radical, and letting group III gas flow so as to make the group III atoms adhere onto to the Si, and then letting chlorine gas flow so as to make chlorine atoms adhere onto the group III atoms on the surface of Si. CONSTITUTION:H radical beams are neutral atoms and are not subjected to electric field acceleration, and the chemical etching of an oxide film is done without the semiconductor suffering shocks by ions which become the cause of damage in usual dry etching. When the compound gas of group III is let flow onto a substrate whose surface is cleaned, the gas decomposes at the surface of the substrata, and group III atoms adhere to the surface of Si. Since atoms such as oxygen, halogen, etc., are easy to adhere onto the group III atoms which adhered, chlorine gas is let flow and made to adhere so as to stabilize it. Group III atoms and chlorine are strong in coupling energy, and once the chlorides of group III atoms cover the surface of the Si, the surface of the Si ceases to be oxidized. When group V gas is let flow to the surface of the Si to which these chlorides adhered, the chlorine is replaced with group V atoms and epitaxial growth begins.
