Abstract: Processing methods described herein comprise forming a metal gate film on a narrow feature and a wide feature and depositing a hard mask on the metal gate film. The hard mask forms on the metal gate film at a top, bottom and sidewalls of the wide feature and on a top of the narrow feature to cover the metal gate film. Some processing methods comprise oxidizing the metal gate film on the narrow feature to convert a portion of the metal gate film to a metal oxide film. Some processing methods comprise etching the metal oxide film from the narrow feature to leave a gradient etch profile. Some processing methods comprise filling the narrow feature and the wide feature with a gap fill material comprising one or more of a metal nitride, titanium nitride (TiN) or titanium oxynitride (TiON), the gap fill material substantially free of seams and voids.

Abstract: Some embodiments of the disclosure relate to methods of modifying a heater pedestal to improve temperature and thickness uniformity. Some embodiments of the disclosure relate to the modified heater pedestals with improved temperature and thickness uniformity. In some embodiments, the height of support mesas in different regions of the pedestal are modified to increase temperature uniformity. In some embodiments, the heater elements are moved above the vacuum channel and purge channel to increase temperature uniformity. In some embodiments, the edge ring is modified to be coplanar with the top of a supported substrate.

Abstract: Methods of manufacturing and processing semiconductor devices (i.e., electronic devices) are described. The methods include treating a surface of a metal gate stack with a radical treatment. The radical treatment may be used to treat one or more layers or surfaces of layers in the metal gate stack. The radical treatment may be performed once or multiple times during the methods described herein. The radical treatment comprises flowing one or more of nitrogen radicals (N2*) and hydrogen radicals (H*) over the surface of the metal gate stack.

Abstract: Methods of forming metal-containing films for electronic devices (e.g., logic devices and/or memory devices) and methods for reducing equivalent oxide thickness (EOT) penalty in electronic devices are disclosed. The methods comprise exposing a substrate surface to a metal precursor, such as titanium chloride (TiCl4), a reducing agent, such as a cyclic 1,4-diene, and a reactant, ammonia (NH3), either simultaneously, partially simultaneously or separately and sequentially to form the metal-containing film.
