Abstract: A semiconductor structure includes: an etch-stop dielectric layer overlying a substrate and including a first opening therethrough; a silicon oxide plate overlying the etch-stop dielectric layer and including a second opening therethrough; a first conductive structure including a first electrode and extending through the second opening and the first opening; a memory film contacting a top surface of the first conductive structure and including a material that provides at least two resistive states having different electrical resistivity; and a second conductive structure including a second electrode and contacting a top surface of the memory film.

Abstract: A resistance feedback laryngoscope contains a pushing grip, a trigger pad, a rotary shaft, a first transmitting rod, a second transmitting rod, and a two-step levering blade. The pushing grip includes a curved front side connecting with the two-step levering blade. The two-step levering blade includes a first movable blade, a second movable blade, and a fixed blade. The first transmitting rod and the second transmitting rod connect with the rotary shaft fixed on a drive post with a resilient element. The resilient element has a first foot butting against a locking peg proximate to the drive post and has a second foot being biased against a side piece of the rotary shaft. The trigger pad contacts with the pushing grip and curves upward slightly, and the trigger pad includes an arcuate groove formed therein, a bottom end of the arcuate groove contacts with the side piece of the rotary shaft.
