Atmospheric cold plasma jet coating and surface treatment
A system and method are described for depositing a material onto a receiving surface, where the material is formed by use of a plasma to modify a source material in-transit to the receiving surface. The system comprises a microwave generator electronics stage. The system further includes a microwave applicator stage including a cavity resonator structure. The cavity resonator structure includes an outer conductor, an inner conductor, and a resonator cavity interposed between the outer conductor and the inner conductor. The system also includes a multi-component flow assembly including a laminar flow nozzle providing a shield gas, a zonal flow nozzle providing a functional process gas, and a source material flow nozzle configured to deliver the source material. The source material flow nozzle and zonal flow nozzle facilitate a reaction between the source material and the functional process gas within a plasma region.
Structures including multiple carbon layers and methods of forming and using same
Methods and systems for forming a structure including multiple carbon layers and structures formed using the method or system are disclosed. Exemplary methods include forming a first carbon layer and a second carbon layer, wherein a density and/or other property of the first carbon layer differs from the corresponding property of the second carbon layer.
PULSED PLASMA (DC/RF) DEPOSITION OF HIGH QUALITY C FILMS FOR PATTERNING
Embodiments of the present disclosure relate to methods for depositing an amorphous carbon layer onto a substrate, including over previously formed layers on the substrate, using a plasma-enhanced chemical vapor deposition (PECVD) process. In particular, the methods described herein utilize a combination of RF AC power and pulsed DC power to create a plasma which deposits an amorphous carbon layer with a high ratio of sp3 (diamond-like) carbon to sp2 (graphite-like) carbon. The methods also provide for lower processing pressures, lower processing temperatures, and higher processing powers, each of which, alone or in combination, may further increase the relative fraction of sp3 carbon in the deposited amorphous carbon layer. As a result of the higher sp3 carbon fraction, the methods described herein provide amorphous carbon layers having improved density, rigidity, etch selectivity, and film stress as compared to amorphous carbon layers deposited by conventional methods.
Si-containing film forming precursors and methods of using the same
Methods are disclosed for forming a Silicon Metal Oxide film using a mono-substituted TSA precursor. The precursors have the formula: (SiH3)2N—SiH2-X, wherein X is selected from a halogen atom; an isocyanato group; an amino group; an N-containing C4-C10 saturated or unsaturated heterocycle; or an alkoxy group.
