    摘要: Embodiments of the present disclosure generally relate to processing an optical workpiece containing grating structures on a substrate by deposition processes, such as atomic layer deposition (ALD). In one or more embodiments, a method for processing an optical workpiece includes positioning a substrate containing a first layer within a processing chamber, where the first layer contains grating structures separated by trenches formed in the first layer, and each of the grating structures has an initial critical dimension, and depositing a second layer on at least the sidewalls of the grating structures by ALD to produce corrected grating structures separated by the trenches, where each of the corrected grating structures has a corrected critical dimension greater than the initial critical dimension.

    摘要: Implementations of the present disclosure generally relate to hardmask films and methods for depositing hardmask films. More particularly, implementations of the present disclosure generally relate to tungsten carbide hardmask films and processes for depositing tungsten carbide hardmask films. In one implementation, a method of forming a tungsten carbide film is provided. The method comprises forming a tungsten carbide initiation layer on a silicon-containing surface of a substrate at a first deposition rate. The method further comprises forming a tungsten carbide film on the tungsten carbide initiation layer at a second deposition rate, wherein the second deposition rate is greater than the first deposition rate.

    摘要: A SiC Freestanding Film Structure capable of preventing a functional surface of a SiC Freestanding Film Structure from being affected by a film thickness and improving strength by increasing the film thickness, the SiC Freestanding Film Structure is formed by depositing a SiC layer through a vapor deposition type film formation method. The SiC layer is deposited with respect to a first SiC layer serving as a functional surface in the SiC Freestanding Film Structure. Focusing on the functional surface and a non-functional surface positioned on front and back sides of any particular portion, the functional surface has smoothness higher than that of the non-functional surface.
