Patent ID: 10815585

Abstract:
The susceptor for an epitaxial deposition reactor comprises a disc-shaped portion (11, 12) which is adapted to be placed horizontally and which at the top has at least one cylindrical pocket (200) where a substrate (100) to be subjected to an epitaxial deposition process is placed; the pocket (200) has a bottom; one or more conduits (13) fluidically connected to an intake system (300) open on the bottom of the pocket (200); when a substrate (100) is placed on the bottom of the pocket (200) and the intake system (300) is active, the substrate (100) remains adhering to the bottom of the pocket (200). In particular: the upper body 12) superiorly has the pocket (200), the conduits (13) vertically cross only the upper body (12), the conduits (13) are fluidically connected to a plenum (14) located between the lower body (11) and the upper body (12) below the pocket (200), the plenum (14) is fluidically connected to the intake system (300); whereby when a substrate (100) is placed on the bottom of the pocket (200) and the intake system (300) is active, the lower body (11) and the upper body (12) remain united.
