A high performance GAA FET is described in which vertically stacked silicon nanowires carry substantially the same drive current as the fin in a conventional FinFET transistor, but at a lower operating voltage, and with greater reliability. One problem that occurs in existing nanowire GAA FETs is that, when a metal is used to form the wrap-around gate, a short circuit can develop between the source and drain regions and the metal gate portion that underlies the channel. The vertically stacked nanowire device described herein, however, avoids such short circuits by forming insulating barriers in contact with the source and drain regions, prior to forming the gate. Through the use of sacrificial films, the fabrication process is almost fully self-aligned, such that only one lithography mask layer is needed, which significantly reduces manufacturing costs.

It is an object to provide a semiconductor device in which power consumption can be reduced. It is another object to provide a highly reliable semiconductor device using a programming cell, such as a programmable logic device (PLD). In accordance with a change in a configuration of connections between basic blocks, power supply voltage furnishing to the basic blocks is changed. That is, when the structure of connections between the basic blocks is such that a basic block does not contribute to a circuit, the supply of the power supply voltage to this basic block is stopped. Further, the supply of the power supply voltage to the basic blocks is controlled using a programming cell formed using a field effect transistor whose channel formation region is formed using an oxide semiconductor, the field effect transistor having extremely low off-state current or extremely low leakage current.

A high data availability write-caching storage controller has a volatile memory with a write cache for caching write cache data, a non-volatile memory, a capacitor pack for supplying power for backing up the write cache to the non-volatile memory in response to a loss of main power, and a CPU that determines whether reducing an operating voltage of the capacitor pack to a new value would cause the capacitor pack to be storing less energy than required for backing up the current size write cache to the non-volatile memory. If so, the CPU reduces the size of the write cache prior to reducing the operating voltage. The CPU estimates the capacity of the capacitor pack to store the required energy based on a history of operational temperature and voltage readings of the capacitor pack, such as on an accumulated normalized running time and warranted lifetime of the capacitor pack.

A method of forming a composite gate structure for a planar MOSFET device, as well as for vertical, double gate, FINFET device, has been developed. The method features a composite gate structure comprised of an overlying silicon gate structure shape, and an underlying titanium nitride gate structure shape. The titanium nitride component allows a lower work function, and thus lower device operating voltages to be realized when compared to counterpart gate structures formed with only polysilicon. A novel, two step gate structure definition procedure, featuring an anisotropic first etch procedure for definition of the polysilicon gate structure shape, followed by a wet or dry isotopic second etch procedure for definition of the titanium nitride gate structure shape, is employed.

The GaN / AlN superlattice mitigates the strain between a GaN / sapphire template and a multiple quantum well heterostructure active region, allowing the use of high Al mole fraction in the active region, and therefore emission in the deep UV wavelengths.

A fully automatic deionizer comprising five sub-systems for removing ionic contaminants from various liquids at low energy consumption is devised. Based on the charging-discharging principle of capacitors, the deionizer conducts deionization through applying a low DC voltage to its electrodes for adsorbing ions, while more than 30% of the process energy is recovered and stored by discharging the electrodes. At the mean time of discharge, surface of the electrodes is regenerated on site and reset for performing many more cycles of deionization-regeneration till the desirable purification is attained. In one moment, both deionization and regeneration proceed simultaneously on different groups of electrode modules, and in the next moment the electrode modules quickly switch the two processes. Such swift reciprocating actions are engaged in synchronized coordination of sub-systems of electrode modules, energy management, fluid flow, and automatic control.

The support structure can take the form of grid having a number of circular apertures. When a voltage is applied to the electrodes, portions of the film held at the aperture of the support structure can bulge due to the electrostriction phenomenon. The resultant “bubbles” can be modulated to generate sonic vibrations, or can be used to create a variable surface for airflow control.

Efficiency of leading out light released from an active layer, i.e. the external quantum efficiency, can be improved remarkably by processing a light lead-out surface to have an embossment. A layer containing a p-type dopant like magnesium (Mg) is deposited near the surface of a p-type GaN layer to diffuse it there, and a p-side electrode is made on the p-type GaN layer after removing the deposited layer. This results in ensuring ohmic contact with the p-side electrode, preventing exfoliation of the electrode and improving the reliability.

An improved light responsive semiconductor switch with shorted load protection capable of successfully interrupting a load overcurrent. The switch is includes an output transistor which is triggered by a photovoltaic element to connect a load to a power source thereof, and an overcurrent sensor which provides an overcurrent signal upon seeing an overcurrent condition in the load. A shunt transistor is connected in series with a current limiting resistive element across the photovoltaic element to define a shunt path of flowing the current from the photovoltaic element through the current limiting resistive element away from the output transistor. A latch circuit is included to be energized by the photovoltaic element and to provide an interruption signal once the overcurrent signal is received and hold the interruption signal. The interruption signal turns on the shunt transistor so as to flow the current from the photovoltaic element through the shunt path, thereby turning off the output transistor for interruption of the overcurrent. The current limiting resistive element is connected in series with the shunt transistor to limit the current from the photovoltaic element when the shunt transistor is turned on, thereby providing a supply voltage from the photovoltaic element to the latch circuit. Thus, the latch circuit is enabled to keep providing the interruption signal for reliable interruption of the overcurrent.
