  • Patent number: 7687855
    Abstract: To provide a semiconductor device that can effectively suppress the short channel effect without deterioration of carrier migration, an impurity ion is added from a direction of the <110> axis with respect to a silicon substrate on forming a punch through stopper under the gate electrode. In this invention, because the addition of the impurity is conducted by utilizing the principal of channeling, the impurity can be added with a small amount of scattering suppressing damage on the surface of the silicon substrate. A channel forming region having an extremely small impurity concentration and substantially no crystallinity disorder is formed.

  • Publication number: 20100072683
    Abstract: To form a relief valve for preventing the generation of the cavitation phenomenon into a simple and accurately operable structure, there are provided a central thin wall portion and a fixing portion in an elastic diaphragm provided in the partition member to have the fixing portion fixed in position. A relief valve is integrally formed with an outer peripheral portion of the fixing portion. The relief valve is provided with an inclined surface formed on the side of a secondary liquid chamber and a recessed portion opened on the side of a primary liquid chamber and has a difference in rigidity in the circumferential direction. When the primary liquid chamber turns negative pressure, a hydraulic liquid in the secondary liquid chamber opens the relief valve and leaks to the primary liquid chamber so as to prevent the generation of the cavitation phenomenon.

  • Patent number: 7671425
    Abstract: In a semiconductor device, pining regions 105 are disposed along the junction portion of a drain region 102 and a channel forming region 106 locally in a channel width direction. With this structure, because the spread of a depletion layer from a drain side is restrained by the pining regions 105, a short-channel effect can be restrained effectively. Also, because a passage through which carriers move is ensured, high mobility can be maintained.

In a case where electric current is applied via the third electrodes, a second potential difference between the second electrodes is detected. Based on the detected two types of potential differences and physical data of the subject, the visceral fat amount of the subject is calculated.
