A method of fabricating a plurality of FinFETs on a semiconductor substrate in which the gate width of each individual FinFET is defined utilizing only a single etching process, instead of two or more, is provided. The inventive method results in improved gate width control and less variation of the gate width of each individual gate across the entire surface of the substrate. The inventive method achieves the above by utilizing a modified sidewall image transfer (SIT) process in which an insulating spacer that is later replaced by a gate conductor is employed and a high-density bottom up oxide fill is used to isolate the gate from the substrate.

When images are needed to be displayed, one pixel is configured by selecting an indented state. Thus, smooth display can be conducted.

Water-based invisible red fluorescent inks provide machine-readable, inverse contrast invisible images and can be printed using conventional ink jet printers. The inks employ rare earth complexed ligand fluorophores having narrow excitation and emission spectra. In one embodiment the images are printed with an ink comprising water and a water-soluble organic fluorescent fluorophore, which when printed and dried on paper is invisible to the eye and fluoresces in the green to infrared range, e.g., from about 550 to 1200 nm, when irradiated with short wave length UV radiation, e.g., from 230 nm to 280 nm. The highly specific excitation and emission rates, coupled with a high inverse contrast on papers of all colors, makes them particularly useful as ink jet inks for postal and other purposes.

With such an arrangement, that junction may be relatively long and have a relatively large cross-sectional area thus making a strong junction even in smaller femoral implants.

Electrical characteristics of transistors using an oxide semiconductor are greatly varied in a substrate, between substrates, and between lots, and the electrical characteristics are changed due to heat, bias, light, or the like in some cases. In view of the above, a semiconductor device using an oxide semiconductor with high reliability and small variation in electrical characteristics is manufactured. In a method for manufacturing a semiconductor device, hydrogen in a film and at an interface between films is removed in a transistor using an oxide semiconductor. In order to remove hydrogen at the interface between the films, the substrate is transferred under a vacuum between film formations. Further, as for a substrate having a surface exposed to the air, hydrogen on the surface of the substrate may be removed by heat treatment or plasma treatment.

An object is to reduce a pseudo contour occurring in time gray scale method display. One pixel is divided into m subpixels (m is an integer of m≧2), and the area of the (s+1)th subpixel (1≦s≦m−1) is twice the area of the s-th subpixel. Further, one frame is divided into n subframes (n is an integer of n≧2), and a lighting period of the (p+1)th subframe (1≦p≦n−1) is 2m times longer than a lighting period of a p-th subframe. Then, at least one subframe of the n subframes is divided into a plurality of subpixels each having a lighting period shorter than that of the subframe so that the n subframes are increased to t subframes (t>n). In at least one subframe of the t subframes, lighting periods of the subframes in a lighting state are sequentially added by the m subpixels, so that a gray scale of the pixel is expressed.

A character reading technique recognizes character strings in grayscale images where characters within such strings have poor contrast, are variable in position or rotation with respect to other characters in the string, or where portions of characters in the string are partially obscured. The method improves classification accuracy by improving the robustness of the underlying correlation operation. Characters are divided into regions before performing correlations. Based upon the relative individual region results, region results are combined into a whole character result. Using the characters that are read, a running checksum is computed and, based upon the checksum result, characters are replaced to produce a valid result.

A gas concentration sensor comprises an ultrasonic element 33 opposite a reflection surface 34. A depression 34a is formed on an edge portion of a reflection surface 34 which is in contact with a side wall of a measurement chamber 32 such that a bottom surface of the depression 34a is substantially in parallel with the reflection surface 34. The distance between the ultrasonic element 33 and the edge portion of the reflection surface 34 becomes greater than the distance between the ultrasonic element 33 and a central portion of the reflection surface 34. As a result, an indirect wave, which impinges obliquely on the side wall of the measurement chamber 32 and propagates along the side wall, is reflected from the bottom surface of the depression 34a and propagates. Thus, the propagation distance of this indirect wave becomes greater as compared to the case where the reflection surface 34 is flat, so that the indirect wave is not combined with a direct wave in the vicinity of a modulation point of the direct wave. That is, since the modulation point of the direct wave can be detected accurately, a time interval between a modulation point of a transmitted wave and that of a received wave can be measured as the propagation time of an ultrasonic wave, thereby enabling accurate determination of gas concentration.

The earphone antenna having such a structure can eliminate high-frequency adverse effects on a wireless device transmitted from a human body via an earphone.
