Abstract

Transport phenomena and surface reaction rate in the small- batch horizontal cold-wall silicon epitaxial reactor at atmospheric pressure are studied using computational fluid dynamics. According to the effect and the role of the gas inlet in a trichlorosilane-hydrogen system, the combination of two or three gas inlet zones is considered to achieve the uniform epitaxial film profile. The susceptor rotation rate is also a parameter to adjust the film thickness profile.
