Abstract: A button mechanism includes a button, a module, and a thin sheet spring. The thin sheet spring is in physical communication with the button and with the module. The thin sheet spring exerts a tension force on the button and the module to bias the button toward a normal position. In response to a force greater than the tension force being exerted on the button, a portion of the thin sheet stretches to enable the button to be placed in a contact position. In response to the force being removed from the button, the tension force causes the thin sheet to snap back to an original position and biases the button toward the normal position.

Abstract: A semiconductor device and a fabrication method thereof are provided. The semiconductor device includes a semiconductor body, a first doped region, a second doped region, a gate and a dielectric layer. The semiconductor body is disposed on a dielectric substrate and has a protrusion portion, a first portion and a second portion. The first portion and the second portion are respectively disposed at two opposite sides of the protrusion portion. The first doped region is disposed in a top of the protrusion portion. The second doped region is disposed in an end of the first portion far away from the protrusion portion. The gate is disposed on the first portion and adjacent to the protrusion portion. The dielectric layer is disposed between the gate and the protrusion portion, and between the gate and the first portion.

Abstract: A memory device includes: a substrate; a channel layer on the substrate, in which the channel layer includes a T-shape having a horizontal portion with a first end and a second end and a vertical portion having a third end; a gate structure on a side of the vertical portion; an oxide-nitride-oxide (ONO) layer between the gate structure and the vertical portion; a source region on the first end of the horizontal portion; and a drain region on the third end of the vertical portion.

Abstract: The semiconductor device with a ?-shaped semiconductor conductive layer manufactured by the manufacturing method thereof utilizes two pathways of the ?-shaped semiconductor conductive layer connected to the silicon layer of a silicon-on-insulator (SOI) substrate for heat dissipation, so as to reduce the self-heating effects (SHEs). Furthermore, the semiconductor device of the invention utilizes the self-aligned technique to form a self-aligned structure with a gate unit and the silicon layer, so that the process is simple, the production cost is reduced, the compacted ability and the yield are improved, the off current and short-channel effects (SCEs) are still similar to a conventional UTSOI MOSFET, and the stability and the reliability are therefore superior.
