摘要:
An optical fiber sensing system carries out accurate measurements while avoiding measurement noise factors. For example, effects of the emission power of a light source, fiber insertion loss, fluctuations in the sensitivity of a photo detector, fluctuations in the amplitude of an amplifier, the loss of optical energy due to bending of an optical fiber, the loss of optical energy due to connecting two or more optical fibers, and gain fluctuations of electric circuitry provided on a platform do not affect measurements. A reflective sensor is connected to an end of an optical fiber connected to a light source. The light source outputs physical measurement light and reflected light coming from the reflective sensor is separated into two beams of light. Information on the physical quantity of a measurement target object is detected on the basis of an intensity ratio of the two beams.

A semiconductor storage device has a single gate electrode formed on a semiconductor substrate through a gate insulation film. First and second memory function bodies formed on both sides of the gate electrode. A P-type channel region is formed in a surface of the substrate on the side of the gate electrode. N-type first and second diffusion regions are formed on both sides of the channel region. The channel region is composed of an offset region located under the first and second memory function bodies and a gate electrode beneath region located under the gate electrode. The concentration of a dopant which imparts a P-type conductivity to the offset region is effectively lower than the concentration of a dopant which imparts the P-type conductivity to the gate electrode beneath region. This makes it possible to provide the semiconductor storage device which is easily shrunk in scale.

A semiconductor device and a fabrication method thereof are disclosed. A silicon nitride film is formed over a silicon semiconductor substrate. Impurity ions are then implanted into desired areas of the silicon semiconductor substrate, so that nitrogen atoms and silicon atoms from the silicon nitride film are incorporated into the surface of the silicon semiconductor substrate together with introduction of impurity ions. The silicon semiconductor substrate has a minimized content of oxygen mixed thereinto and restored crystal defects filled by nitrogen atoms upon implanting of impurity ions. The fabricated semiconductor device is free from a trade-off relation between gate-electrode depletion and junction current leakage, and short-channel effects.

A printed material (5) has a transparent base member (51), a first image layer (52) formed on the base member, an intermediate layer (53) formed on the first image layer, and a second image layer (54) formed on the intermediate layer. The intermediate layer has a lower white background layer (531) positioned above the first image layer, a light blocking layer (532) positioned above the lower white background layer, and an upper white background layer (533) positioned above the light blocking layer. In the printed material, a thickness of the light blocking layer is uneven in conformity with undulation of the first image layer, and therefore a surface of the intermediate layer which is in contact with the second image layer is flat. With this structure, it is possible to prevent or suppress the undulation of the first image layer from appearing in the second image layer.

A solder layer, a substrate for device joining utilizing the same and a method of manufacturing the substrate are provided whereby the device joined remains thermally unaffected, an initial bonding strength in solder joint is enhanced and the device can be soldered reliably. The solder layer formed on a base substrate (2) consists of a plurality of layers (5a) of a solder free from lead, which are different in its phase from one another. They are constituted by a layer of a phase that is completely melted, and a layer of a phase that is not completely melted at a temperature not less than a eutectic temperature of the solder. The solder layer (5) can be applied to a device joining substrate (1) comprising an electrode layer (4) formed on the base substrate (2) and the solder layer (5) formed on the electrode layer.
