    Abstract: The present disclosure is directed to methods and systems for depositing a material within a gap of a substrate in a cyclic deposition process. The methods and systems utilize an inhibitor to preferentially blocks chemisorption of a subsequently introduced first precursor at a portion of available chemisorption sites in the gap to promote deeper penetration of the first precursor into the gap and/or more uniform chemisorption of the first precursor in the gap used in forming a desired material.

    Abstract: Herein disclosed are systems and methods related to semiconductor processing device including a manifold including a bore configured to deliver a gas to a reaction chamber, the manifold including a first block mounted to a second block, the first and second mounted blocks cooperating to at least partially define the bore. The manifold may further comprise an insulator cap disposed about the first block or the second block. The semiconductor processing device may comprise at least three valve blocks mounted to the second block so that a precursor backflow is prevented. Heater rod(s) can extend through the second block to a location adjacent the first block.

    Abstract: The present disclosure relates to methods for depositing an elemental metal or semimetal-containing material on a substrate by a cyclic deposition process, to an elemental metal or semimetal-containing layer, to a semiconductor structure and a device, and to deposition assemblies for depositing elemental metal or semimetal-containing material on a substrate. A method according to the current disclosure comprises providing a substrate in a reaction chamber, providing a metal or a semimetal precursor to the reaction chamber in a vapor phase, and providing a reducing agent into the reaction chamber in a vapor phase to form elemental metal or semimetal-containing material on the substrate. The reducing agent according to the method comprises a cyclohexadiene compound selected from compounds comprising a germanium-containing substituent.

    Abstract: A method for forming a structure with a hole on a substrate is disclosed. The method may comprise: depositing a first structure on the substrate; etching a first part of the hole in the first structure; depositing a plug fill in the first part of the hole; depositing a second structure on top of the first structure; etching a second part of the hole substantially aligned with the first part of the hole in the second structure; and, etching the plug fill of the first part of the hole and thereby opening up the hole by dry etching. In this way 3-D NAND device may be provided.

    Abstract: A reactor system with stuck lift pin detection. The system includes a reaction chamber, a susceptor for supporting wafers in an interior space of the reaction chamber, and an elevator for raising and lowering the susceptor in the interior space. Further, the system includes a lift pin supported by and extending vertically through the susceptor to travel between an up and a down position with movements of the susceptor by the elevator, and a landing pad is provided in the system for receiving a base of the lift pin when the lift pin is in the down position. Significantly, the system also includes a sensor assembly with a sensor positioned at least partially within the interior space of the reaction chamber. An output signal of the sensor is indicative of whether the lift pin is sticking or seizing during travel through the susceptor.
