Abstract: A method includes flowing an evaporated low vapor pressure organic molecule (OM) into a processing chamber including a substrate. The method further includes depositing, in the processing chamber, the low vapor pressure OM onto at least a portion of the substrate at a first temperature and a first pressure to form a self-assembled monolayer (SAM) on at least the portion of the substrate. The method further includes annealing, in the processing chamber, the SAM on at least the portion of the substrate at a second temperature and a second pressure. The second pressure is greater than the first pressure and the second temperature is greater than the first temperature.

Abstract: A high-pressure processing system for processing a substrate includes a first chamber, a pedestal positioned within the first chamber to support the substrate, a second chamber adjacent the first chamber, a vacuum processing system configured to lower a pressure within the second chamber to near vacuum, a valve assembly between the first chamber and the second chamber to isolate the pressure within the first chamber from the pressure within the second chamber, and a gas delivery system configured to introduce a processing gas into the first chamber and to increase the pressure within the first chamber to at least 10 atmospheres while the processing gas is in the first chamber and while the first chamber is isolated from the second chamber.

Abstract: Exemplary methods of semiconductor processing may include methods for nonconformally building up silicon-and-oxygen-containing material where the top of the feature preferentially fills at a slower rate as compared to the bottom of the feature. Such methods may include iterative nonconformal etching operations and/or iterative nonconformal inhibition operations. For example, after building up a layer comprising silicon-and-oxygen-containing material, the layer may be nonconformally etched before building up another layer comprising silicon-and-oxygen-containing material. In another example, in the building up of the layer, an inhibitor may be introduced preferentially at and near the top of the features to provide nonconformal buildup of the silicon-and-oxygen-containing material.

Abstract: The present disclosure generally relates to a substrate processing chamber, a substrate processing apparatus, and a substrate processing method for self-assembled monolayer (SAM) deposition of low vapor pressure organic molecules (OM) followed by further substrate processing, such as atomic layer deposition.

Abstract: Two-dimensional (2D) materials formed in very thin layers improve the operation of semiconductor devices. However, forming a contact on 2D material tends to damage and penetrate the 2D material. A relatively gentle etch process has been developed that is very selective to the 2D material and allows vertical holes to be etched down to the 2D material without damaging or penetrating the 2D material. A low-power deposition process forms a protective liner when performing the metal fill to further prevent damage to the 2D material when forming the metal contacts in the holes. These processes allow a vertical metal contact to be formed on a planar 2D material or a vertical sidewall contact be formed in a 3D NAND without damaging the 2D material. This increases the contact area, reduces the contact resistance, and improves the performance of the 2D material in the device.
