Pulsed plasma (DC/RF) deposition of high quality C films for patterning

Methods for depositing an amorphous carbon layer onto a substrate, including over previously formed layers on the substrate, use a plasma-enhanced chemical vapor deposition (PECVD) process. In particular, the methods 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 provide amorphous carbon layers having improved density, rigidity, etch selectivity, and film stress as compared to amorphous carbon layers deposited by conventional methods.

11634813 · 2023-04-25 · ·

Embodiments of the present disclosure provide apparatuses for improving gas distribution during thermal processing. In one or more embodiments, an apparatus includes a body, an angled gas source assembly, and a gas injection channel. The gas injection channel has a first half-angle and a second half-angle. The first half-angle is different from the second half-angle. The use of an improved side gas assembly in a processing chamber to direct gas from the center toward the edge of the substrate advantageously controls growth uniformity throughout the substrate. Surprisingly, directing gas through a gas channel with non-uniform half-angles will significantly increase the reaction at or near the edge of the substrate, thereby leading to an improved overall thickness uniformity of the substrate.
