    Abstract: A method and apparatus for depositing thin films onto a substrate is provided. The apparatus includes a gas injection structure that is positioned within a reaction chamber that has a platform. The gas injection structure may be positioned above or below the platform and comprises a first gas injector and a second gas injector. The first gas injector is in fluid communication with a first reactant source and a purge gas source. Similarly, the second gas injector is in fluid communication with a second reactant source and a purge gas source. The first and second injectors include hollow tubes with apertures opening to the reaction chamber. In one configuration, the tubes are in the form of interleaved branching tubes forming showerhead rakes. Methods are provided for deposition, in which multiple pulses of purge and reactant gases are provided for each purge and reactant step.

    Abstract: A method forms a gate stack for a semiconductor device with a desired work function of the gate electrode. The work function is adjusted by changing the overall electronegativity of the gate electrode material in the region that determines the work function of the gate electrode during the gate electrode deposition. The gate stack is deposited by an atomic layer deposition type process and the overall electronegativity of the gate electrode is tuned by introducing at least one pulse of an additional precursor to selected deposition cycles of the gate electrode. The tuning of the work function of the gate electrode can be done not only by introducing additional material into the gate electrode, but also by utilizing the effects of a graded mode deposition and thickness variations of the lower gate part of the gate electrode in combination with the effects that the incorporation of the additional material pulses offers.

    Abstract: An atomic layer deposition apparatus, having a first series of high pressure gas injection openings and a first series of exhaust openings that are positioned such that they together create a first high pressure/suction zone within each purge gas zone, wherein each first high pressure/suction zone extends over substantially the entire width of the process tunnel and wherein the distribution of the gas injection openings that are connected to the second purge gas source and the distribution of the gas exhaust openings within the first high pressure/suction zone, as well as the pressure of the second purge gas source and the pressure at the gas exhaust openings are such that the average pressure within the first high pressure/suction zone deviates less than 30% from a reference pressure which is defined by the average pressure within process tunnel when no substrate is present.

    Abstract: A wafer boat cooldown device comprising a bottom plate and a rotatable table that is rotatable between a number of index positions. The rotatable table comprises at least two wafer boat positions for supporting a wafer boat. A vertically extending wall structure is mounted on the rotatable table and creates, at each wafer boat position, a wafer boat chamber having a gas supply area and a gas discharge area. The wafer boat cooldown device further comprises a plenum chamber which extends under the bottom plate. The plenum chamber accommodates at least one gas/liquid heat exchanger.
