Silane Pyrolysis to Silicon Rod in a Bell

Chemical vapor deposition (CVD) at high temperature and pressure in a unique bell-jar reactor has been widely applied for high-pure polysilicon production using trichlorosilane (TCS) as a precursor. Silane is an alternative to TCS and used for ultrapure polysilicon. Nevertheless, silane is so reactive that results in significant homogeneous nucleated fines which lead to low yield and quality

Influence of hydrogen volumetric flow rate on temperature

In the present paper the quantitative relationship between the heat and mass transfer in the Aixtron VP508 hot wall CVD reactor and the epitaxial growth of silicon carbide is determined. The aim of this study was to estimate optimal process conditions for obtaining monocrystalline silicon carbide epi-layers with the most homogenous thickness.

Modeling of chimney CVD reactors

A two-dimensional numerical model employing the finite element method was used to phenomenologically describe the effect of buoyancy forces on fluid flow and growth rate for mass transfer-controlled chemical vapor deposition in chimney reactors. For typical reactor geometries at 0.1 atm pressure, buoyancy effects are insignificant, and fluid flow and growth rate uniformity are

Modeling of Chemical Vapor Deposition Processes

Modeling may be used for both process and reactor optimization purposes. Besides the description of transport phenomena (flow, heat, species), an adequate chemistry model is necessary to predict deposition rates and uniformities and layer compositions.

2020/1/21Chemical vapor deposition (CVD) is an established process for the production of thin solid films for industrial and scientific applications for more than 30 years. CVD is a multiscale process; the process per se takes place in a reactor of the order of cm or even m in average linear size, but the properties of the end product, i.e. the deposited film, refer to micro-/nano- or even atomic
