概要 | Post oxidation annealing (POA) for SiO2/Si interface flatness improvement was examined. Five kinds of Si substrates, which had (100), (110), (111), (511), and (221) orientations, were thermally oxidized and subsequently annealed in pure Ar atmosphere for 5 minutes using a lamp or 1 hour using a furnace annealer, respectively. The flatness of low-index plane interfaces, such as (100), (110) and (111), were improved by POA. However, high-index interfaces of (511) and (221) were rather roughened with low-index micro-facet formation. A reaction at the SiO2/Si interface is thought to occur during high temperature POA process. Low-index plane interfaces, which are considered to have low interface energy, appeared as a result of this reaction. |
