Abstract: A semiconductor structure includes a substrate, at least one dielectric layer and a capacitor structure. The at least one dielectric layer is disposed over the substrate, and the at least one dielectric layer includes a step edge profile. The capacitor structure is disposed over the substrate. The capacitor structure includes a bottom electrode, a capacitor dielectric layer and a top electrode. The bottom electrode covers the step edge profile of the at least one dielectric layer and has a first step profile substantially conformal to the step edge profile of the at least one dielectric layer. The capacitor dielectric layer covers the bottom electrode and has a second step profile substantially conformal to the first step profile. The top electrode covers the capacitor dielectric layer.

Abstract: An oral negative-pressure therapy system includes a container and absorbent insert for the container. The container includes a baffle inside an interior of the container. A fluid passageway extends along the baffle for delivering fluid (e.g., a mixture of air and saliva) into the container. The absorbent insert for absorbing liquid (e.g., saliva) in the container may is over the baffle. At least one of the baffle and the absorbent insert is configured to maintain a fluid flow path between the baffle and the absorbent insert to maintain fluid communication between a fluid inlet and a fluid outlet of the container. The absorbent insert and/or the container may be designed and constructed to burst air bubbles in the aspirated liquid. In one or more embodiments, the absorbent insert is replaceable so that a spent absorbent insert can be replaced with a new, fresh absorbent insert.

Abstract: A safety injector comprises a needle hub attached by a needle, a hollow barrel for engaging with the needle hub and guiding the needle hub to retract into the hollow barrel, and a plunger combination settled in the hollow barrel. The plunger combination comprises a retractable plunger and a hollow plunger partially telescoped with the retractable plunger, wherein at least one raised portion is formed on an outer wall of the retractable plunger and at a telescoping portion for engaging at least one depression formed on an inner wall of the hollow plunger so that when the plunger combination continuously receives a pushing force after the safety injector is used to perform the injection operation, the retractable plunger can smoothly retract into the hollow plunger. Consequently, a space in the hollow barrel can be spared for accommodating the retracted needle hub.
