High transparency integrated enclosure touch screen assembly for a portable hand held device

An integrated enclosure/touch screen assembly. A touch screen assembly consisting of a display mechanism and optical sensor mechanism are enclosed within a single piece cover. The optical sensor mechanism consists of lens structure and optical sensor couple to the lens structure. The single piece cover includes a transparent top surface and the lens structure is embedded within the transparent top surface. The transparent top surface of the single piece cover provides an enclosure that is both dust free and waterproof.
The lens structure of the single piece cover functions by columnating light across the transparent surface. The optical touch sensor is coupled to the lens structure to register contact with the transparent surface via the lens structure by detecting disturbances in the columnated light. In one embodiment, the single piece cover is constructed by embedding the lens structure directly into the transparent surface. This process forms the single piece cover and also may be used to provide various shapes for the outer edges of the cover. The single piece cover eliminates exposed seams of the touch screen assembly. Additionally, the transparent surface is disposed directly above the display without any intervening layers, thereby improving the transmission of light to the display.

Three-Dimensional Semiconductor Device and Manufacturing Method Therefor

A three-dimensional semiconductor device, comprising a plurality of memory cell transistors and a plurality of select transistors at least partially overlapped in the vertical direction, wherein each select transistor comprises a first drain, an active region and a common source formed in the substrate, distributed along the vertical direction, as well as a metal gate distributed around the active region; wherein each memory cell transistor comprises a channel layer distributed perpendicularly to the substrate surface, a plurality of inter-layer insulating layers and a plurality of gate stack structures alternately stacked along the sidewalls of said channel layer, a second drain located on top of said channel layer; wherein said channel layer and said the first drain are electrically connected. In accordance with the three-dimensional semiconductor memory device and manufacturing method of the present invention, the multi-gate MOSFET is formed beneath the stack structure of the memory cell string including vertical channel to serve as the select transistor, this can improve the control characteristics of the gate threshold voltage, reduce the off-state leakage current, prevent the substrate from over-etching, and effectively improve the reliability of the device.
