Abstract: PURPOSE: To provide a manufacturing method that can economically manufacture an epitaxial wafer having a denuded zone of low oxygen concentration whose extent can be adjusted in a single wafer reactor. CONSTITUTION: An Si wafer is placed on a high-temperature susceptor in the reactor, a hydrogen-cleaned process chamber is raised in temperature, and the rotation of the susceptor is maintained with a hydrogen flow. After a 1st diborane highly-doped epitaxial layer is deposited, the temperature is lowered and the hydrogen flow is reduced and after a stable state is entered, a 2nd epitaxial layer is deposited. After the process chamber is cleaned with hydrogen, the susceptor is stopped from rotating and the wafer is taken out while cleaned with nitrogen. After etching is carried out with mixed gas of hydrogen and hydrogen chloride, the hydrogen flow is increased and the hydrogen chloride is stopped; and a next wafer is loaded. The 2nd layer is lower in oxygen content similarly to the 1st layer, but high in resistivity, or 0.1 to 1000 Ωcm.  The extent of the denuded zone can freely be set and reproduced by the deposition of the 1st layer. Variation in resistivity nearby the surface is quick.
