Popis: A tubular hot-wall silicon epitaxial reactor operating at reduced pressure is described. It has been constructed by modifying a commercial low-pressure chemical vapor deposition furnace and is proposed as a potentially cost-effective means of depositing selective epitaxial silicon layers. Defect-free selective epitaxial layers are grown at temperatures as low as 820 o C, following a bake in hydrogen at 900 o C. The lower growth rate in a hot-wall system is found to cause abrupt dopant transitions to be less steep by factor of two in comparison to a cold-wall reactor operating at the same temperature
