ABSTRACT:
Apparatus for performing SPE deposition for growing layers of semiconductive material includes a reaction chamber and means for mounting a substrate wafer and a source wafer in the reaction chamber. The substrate wafer and the source wafer are maintained at a predetermined distance which is less than the mean free path of the reactive species of the oxido-reduction of the semiconductive material. A heater for heating the wafers maintains a temperature difference of 20.degree. C. to 40.degree. C. between the wafers.
