Abstract
The B2H6 - and PH3 - partial pressure dependence of the doping concentration of in-situ doped silicon films, deposited in the temperature range between 600 and 750°C by low pressure chemical vapor deposition has been investigated for two different substrate orientations. In addition, the influence of B2H6 and PH3 and their partial pressure on the silicon growth rate has been studied. It is found that the doping concentration can be controlled over a wide range, and that in the presence of PH3 as well as B2H6 the silicon growth is reduced. In the case of boron doping, the in-situ doping has been used to fabricate delta-doped silicon layers.
