Abstract: Methods and related apparatus for depositing an ashable hard mask (AHM) on a substrate include pulsing a low frequency radio frequency component at a high power. Pulsing low frequency power may be used to increase the selectivity or reduce the stress of an AHM. The AHM may then be used to etch features into underlying layers of the substrate.

Abstract: An energy harvester capable of providing motion from fluid flow, which comprises at least one Magnus cylinder driven to rotate by the movement of the fluid past a fin device. This causes the Magnus cylinder to rotate, and further interactions between the rotating Magnus cylinder and the moving fluid generate a Magnus lifting force. A channel or system may be also provided to direct the fluid flow to the Magnus cylinder. This rotating Magnus cylinder configuration is integrated into a mechanical device that is designed to transfer the Magnus lifting forces into a rotary mechanical motion to drive an electric generator. The device can be utilized in either air or hydraulic environments. A modification of the energy harvester can also be configured to utilize the generated electricity to produce hydrogen for use in fuel cells, or for combustion.

Abstract: A cord wrap with integrally molded light holders and mold and method of making same is disclosed. The light holders are molded in cavities connected by runners. The runners are shaped and positioned to form a cord wrap. After the light holders are broken away from the runners, the runner can be used as a cord wrap to store strings of decorative lights such as those which were held by the light holders.
