A fluorine treatment that can shape the electric field profile in electronic devices in 1, 2, or 3 dimensions is disclosed. A method to increase the breakdown voltage of AlGaN/GaN high electron mobility transistors, by the introduction of a controlled amount of dispersion into the device, is also disclosed. This dispersion is large enough to reduce the peak electric field in the channel, but low enough in order not to cause a significant decrease in the output power of the device. In this design, the whole transistor is passivated against dispersion with the exception of a small region 50 to 100 nm wide right next to the drain side of the gate. In that region, surface traps cause limited amounts of dispersion, that will spread the high electric field under the gate edge, therefore increasing the breakdown voltage. Three different methods to introduce dispersion in the 50 nm closest to the gate are described: (1) introduction of a small gap between the passivation and the gate metal, (2) gradually reducing the thickness of the passivation, and (3) gradually reducing the thickness of the AlGaN cap layer in the region close the gate.

A portable electronic device (100) has a long sideways housing (10) whose both ends are held by the hands of a user and an LCD fitted in the surface of the housing (10). Bulges (42L, 42R) projecting outward are formed on both end portions of the rear face of the housing (10), which both end portions being held by fingers of the user holding the housing. When the fingers and palms of user's hands are placed along the bulges (42L, 42R) with the fingers and palms bent naturally, the device fits the hands and operability is less likely to be impaired even the user violently moves in game play with the device.

A hand-held mobile communication device, such as smart telephone, incorporating sensors and signal conditioning modules for measuring signals from external sources of electromagnetic radiation (EMR) in the low, radio, ultraviolet, and infrared spectral ranges. These include the detector for receiving and monitoring electromagnetic fields originating from various external sources of radiation that pose potential health hazards or may interfere with various electronic devices.

This infrared sensor in combination with a photographic digital camera and a pattern recognition signal processing allows measuring temperatures at specific locations and from optimal distances to the surface of the object to enhance accuracy of non-contact temperature measurements.

A pixel having a transistor which controls a current value supplied to a load, a first storage capacitor, a second storage capacitor, and first to fourth switches is included. After the threshold voltage of the transistor is held in the second storage capacitor, a potential in accordance with a video signal is input to the pixel.

Thus, desired current can be supplied to the load such as a light-emitting element. In addition, a display device with little deviation from luminance specified by the video signal can be provided.
