Beschreibung
Zusammenfassung:	Susceptor for an apparatus for depositing a layer of semiconductor material on a substrate wafer (40), wherein the susceptor comprises a susceptor plate and at least one substrate holder (5) for a substrate wafer (40) on the susceptor plate, the at least one substrate holder (5) has a discoid lower part (10), a substrate carrier ring (20), and supporting elements (30), and the supporting elements (30) are arranged concentrically around the ring centre point of the substrate carrier ring (20), characterized in that the substrate carrier ring (20) has insertion openings and the supporting elements (30) have insertion portions, the insertion portions are arranged interchangeably in at least a part of the insertion openings, and the supporting elements have a radial width of 5 mm or less; apparatus for depositing a layer of semiconductor material on a substrate wafer (40); and a method for depositing an epitaxial layer.
