The effect of the pressure on the static meniscus shape in the case of tube growth by edge-defined film-fed growth (E.F.G.) method

Abstract

In this paper explicit formulas prescribing inner and outer pressure limits are reported in the case of cylindrical tube growth by edge-defined film-fed growth (E.F.G.) method. These formulas are deduced in general for any growth configuration and for any material. If the value of the inner (the outer) pressure is less or more than the prescribed limit, then the inner (the outer) meniscus shape is convex or concave. The advantage of this kind of formulas is that from them special results can be gleaned. With this aim this study was undertaken. Numerical examples are given using the data of the first successful silicon tube growth experiment reported by Eriss et al.
