A single-poly non-volatile memory cell that is fully compatible with nano-scale semiconductor manufacturing process is provided. The single-poly non-volatile memory cell includes an ion well, a gate formed on the ion well, a gate dielectric layer between the gate and the ion well, a dielectric stack layer on sidewalls of the gate, a source doping region and a drain doping region. The dielectric stack layer includes a first oxide layer deposited on the sidewalls of the gate and extends to the ion well, and a silicon nitride layer formed on the first oxide layer. The silicon nitride layer functions as a charge-trapping layer.

An exemplary liquid crystal display (200) includes a plurality of gate lines (201), data lines (202), common lines (210), first pixel electrodes (204) and second pixel electrodes (214). Each of areas defined by one of the first pixel electrodes and an adjacent one of the second pixel electrodes is a pixel unit (208). Each pixel unit is driven by a first TFT (203) and a second TFT (213). The first thin film transistor and the second thin film transistor in each pixel unit are connected to a same one of the gate lines and a same one of the data lines, and to the first pixel electrode and the second pixel electrode respectively. A channel width/length ratio of the first thin film transistor is different from a channel width/length ratio of the second thin film transistor.

A portable water therapy apparatus for the large intestine has a positioning pad, a controller, an inlet tube, an outlet tube, and a nozzle and a switch system. The controller comprises a filtering device, a heating device, a pressure control pump, and a switch system. The inlet tube has two ends, a first end is connected to the pressure control pump of the controller, and a second end is connected to a faucet, which eliminates the need to add water manually.

A method of fabricating a non-volatile memory based on SONOS is disclosed. By masking the peripheral circuit area with a reverse ONO photoresist layer, the residual ONO layer that is not covered by a gate within the memory array area is etched away to expose the substrate. After the etching of the ONO layer, a channel adjustment doping is carried out subsequently using the reverse ONO photoresist layer as an implant mask, thereby forming lightly doped regions next to the gate within the memory array area. Finally, the reverse ONO photoresist layer is then stripped.

An exemplary light guide plate (12) includes a substrate (120) having an emitting surface (124), and a plurality of parallel V-shaped grooves (126) provided at the emitting surface. Each of the V-shaped grooves maintains an oblique angle relative to a long side of the substrate, and the angle is in the range from 5° to 44.9°. An associated device employing the light guide plate can provide good viewing performance.

A memory cell includes an N-type well, three P-type doped regions formed on the N-type well, a dielectric layer formed on the N-type well and between a first doped region and a second doped region of the three P-type doped regions, a first gate formed on the dielectric layer, a charge storage structure formed on the N-type well and between the second doped region and a third doped region of the three P-type doped regions, and a second gate formed on the charge storage structure. Data is stored in the memory cell by injecting electrons based on the channel-hot-hole induced hot-electron injection mechanism, the band-to-band tunneling induced electron injection mechanism and the Fowler-Nordheim tunneling mechanism. Data is erased from the memory cell by ejecting electrons based on the Fowler-Nordheim tunneling mechanism. Whether data is stored in the charge storage structure or not can be distinguished by read operation.

A method for forming a self-aligned pixel electrode of a LCD is introduced. The LCD includes a substrate having a plurality of adjacent pixel electrode regions. A joint side is positioned between each pixel electrode region and its adjacent pixel electrode regions. First, a spacer is formed on the joint sides of the pixel electrode regions, and the spacer has an undercut profile. Then, a transparent conductive layer is formed on the substrate, and the transparent conductive layer that covers the pixel electrode regions is separated from the spacer to form a self-aligned pixel electrode.
