IPC: H01L21/205
Filed: 1989-09-28
Abstract: PURPOSE:To form a single atom layer which is easy to control by a single atom layer growth method with an organometal vapor deposition method by a method wherein nitrogen gas or rare gas is employed as carrier gas of at least group III or group II elements. CONSTITUTION:Organometal compound containing group III or group II elements and hydrite containing group V or group VI elements are transported onto a heated substrate with carrier gas and one single molecule layer of III-V compound semiconductor or II-VI compound semiconductor is built up every cycle of the process. If carrier gases, H2 and TMA, are introduced into the reaction chamber 1 of an organo metal vapor deposition apparatus from a gas introducing inlet 2 and the temperature of a susceptor 4 on which the semiconductor substrate 3 is placed is elevated to perform organometal vapor deposition, the decomposition of TMA is accelerated following the increase of partial pressure of hydrogen.
