Publication number: 20170342542Abstract: A direct-deposition system capable of forming a high-resolution pattern of material on a substrate is disclosed. Vaporized atoms from an evaporation source pass through an aperture pattern of a shadow mask to deposit on the substrate in the desired pattern. Prior to reaching the shadow mask, the vaporized atoms pass through a collimator that operates as a spatial filter that blocks any atoms not travelling along directions that are nearly normal to the substrate surface. As a result, the vaporized atoms that pass through the shadow mask exhibit little or no lateral spread (i.e., feathering) after passing through its apertures and the material deposits on the substrate in a pattern that has very high fidelity with the aperture pattern of the shadow mask. The present invention, therefore, mitigates the need for relatively large space between regions of deposited material normally required in the prior art, thereby enabling high-resolution patterning.Type: ApplicationFiled: May 17, 2017Publication date: November 30, 2017Inventors: Amalkumar P.

The nanotube lengths can be trimmed to uniform heights above the template surface using ultrasonic cutting, for example. The carbon nanotube site density can be controlled by controlling the catalyst site density. Control of the carbon nanotube site density enables various applications. For example, the highest possible site density is preferred for thermal interface materials, whereas, for field emission, significantly lower site densities are preferable.Type: ApplicationFiled: May 23, 2017Publication date: November 30, 2017Inventors: Michael P.
