    Abstract: A reactor system may comprise a first gas source; a second gas source; and a reaction chamber fluidly coupled to the first and second gas sources, wherein a first gas and a second may be supplied to the reaction chamber from the first and second gas sources, respectively, to achieve stability of a reaction chamber pressure. The reactor system may further comprise an exhaust line fluidly coupled to and downstream from the reaction chamber; a vent line fluidly coupled to the first and/or second gas source, and to the exhaust line, wherein the vent line bypasses the reaction chamber; a pressure monitor coupled to the vent line configured to monitor a vent line pressure within the vent line; and/or a vent line conductance control valve coupled to the vent line and configured to adjust in response to feedback from the pressure monitor.

    Abstract: A wafer processing apparatus may be presented. The apparatus may comprise a wafer support provided with a heater for supporting and heating the wafer, a chamber for enclosing and processing the wafer, a showerhead for letting gas in the chamber, a pumping port for removing gas from the chamber, a black wall with a substantially high emissivity provided to the chamber near the pumping port and configured to partly encircle the wafer support; and a white wall with a substantially low emissivity provided to the chamber on opposite side of the pumping port and configured to partly encircle the wafer support.

    Abstract: A method and system for depositing a material on one or more substrates by atomic layer deposition. The method comprising a step of performing a pulse (1) of a precursor of said material, wherein at least one of the average flow rate (f) and the average partial pressure (r) of said precursor over a first half (2) of the pulse (1) is higher than over a second half (3) of the pulse (1).

    Abstract: A reactor system may comprise a reaction chamber enclosed by a chamber sidewall, and a susceptor disposed in the reaction chamber between a reaction space and a lower chamber space comprised in the reaction chamber. The susceptor may comprise a pin hole disposed through the susceptor such that the pin hole is in fluid communication with the reaction space and the lower chamber space, and such that the reaction space is in fluid communication with the lower chamber space. A lift pin may be disposed in the pin hole. The lift pin may comprise a pin body comprising a pin channel, defined by a pin channel surface, disposed in the pin body such that the reaction space is in fluid communication with the lower chamber space when the lift pin is disposed in the pin hole.
