Abstract:
A method for fabricating integrated capacitors, of particular utility in forming a ferroelectric capacitor array for a ferroelectric memory integrated circuits, begins with provision of a substrate. The substrate is typically a partially-processed CMOS integrated circuit wafer coated with an adhesion layer. Upon the substrate is deposited a bottom electrode layer, typically of noble metal, a dielectric layer, typically doped PZT, and a top electrode layer, typically a noble metal oxide. Next is deposited a hardmask layer of strontium ruthenium oxide, followed by a photoresist layer. The photoresist layer is aligned, exposed, developed, and cured as known in the art of integrated circuit photolithography. The resulting stack is then dry etched to remove undesired portions of the hardmask layer, the top electrode layer, and the dielectric layer. A principle advantage of the process is that a single photomasking operation is sufficient to define the top electrode and dielectric layers.
Abstract:
A urine bag cleaning manifold capable of pre-mixing a cleaning solution and water for washing one or more urine bags. The bags are then rinsed and allowed to dry. The urine bag cleaning manifold is adapted for attaching to a bathroom sink faucet, bathtub faucet and other faucets for circulating the warm water from the faucet and the cleaning solution therethrough. The cleaning manifold includes a flexible inlet tube having a first end and a second end. The first end of the inlet tube is adapted for connection to the faucet. The second end of the inlet tube is attached to an inlet of a water inlet valve. An outlet of the water inlet valve is attached to a first end of an upstream mixing section. The upstream mixing section is part of a hollow manifold body. The hollow manifold body also includes a downstream discharge section. A second end of the mixing section is attached to a first end of the discharge section. A cleaning solution container is mounted on top of a cleaning solution valve. The cleaning solution valve is attached to sides of an opening in an upper portion of the mixing section. A plurality of outlet valves are attached to sides of openings in a lower portion of the discharge section. A first end of a plurality of outlet tubes is attached to the outlet valves. A second end of the outlet tubes is adapted for attachment to the urine bags.
Abstract:
The invention provides a wheeled apparatus for transporting a brake assembly and/or a tire assembly from an aircraft. The apparatus contains a slideable hollow housing which can be adjusted in height by a jack associated with the apparatus. A brake assembly can be placed within the housing for transportation or storage. On the bottom front of the housing is a stand for removing a tire assembly.
