摘要

本文研究了在工业反应器的相同运行条件下,在500-550/spl℃的低温和20-100 Pa的压力范围内,通过改变晶圆之间的距离(6 - 60 mm),研究了SiH/sub / 4未掺杂硅薄膜的低压化学气相沉积(LPCVD)。为了确定导致膜沉积的气相和表面反应的动力学常数,对实验数据拟合了一个简单的塞流模型。

Contribution of gas phase reactions to the growth rate of LPCVD silicon films in the temperature range from 500 to 550/spl deg/C
In this paper we have investigated the low pressure chemical vapor deposition (LPCVD) of undoped silicon films from SiH/sub 4/ at low temperatures in the range of 500-550/spl deg/C and the pressure range of 20-100 Pa by means of a variable distance between wafers, ranging from 6 to 60 mm within the same run of an industrial reactor. A simple plug flow model was fitted to the experimental data in order to determine the kinetic constants of the gas phase and surface reactions responsible for the film deposition.
