A pulse wave velocity measurement device comprises a pulse wave detection unit (110) for detecting a pulse wave in a living body, a pulse wave velocity calculation unit (120) for calculating a pulse wave velocity on basis of the pulse wave detected by the pulse wave detection unit (110), and a pulse wave velocity correction unit (130) for correcting the pulse wave velocity calculated by the pulse wave velocity calculation unit (120) so as to eliminate an increment in the pulse wave velocity that results from influence of hydrostatic pressures caused according to a position of the living body. Thus, the pulse wave velocity measurement device can be provided that are capable of accurate measurement of the pulse wave velocity without being influenced by the hydrostatic pressures caused according to the position of the living body.

In a display panel, a conductive member subjected to a prescribed electric potential lower than an anode potential is disposed on a first insulating substrate at a location spaced apart from an anode terminal subjected to the anode potential. An insulating member is disposed on the conductive member such that the insulating member includes a part located closer to the anode terminal than an end, on a side facing the anode terminal, of the conductive member and such that a gap is provided between the part and the first insulating substrate.

Gate electrodes of an N-channel transistor and a P-channel transistor are formed on a semiconductor substrate with a gate insulator therebetween. After conducting a first thermal treatment to the gate electrodes, N-type heavily doped diffusion layers to be a source or a drain of the N-channel transistor are formed using the gate electrode of the N-channel transistor as a mask. After conducting a second thermal treatment to the N-type heavily doped diffusion layers at a lower temperature than that of the first thermal treatment, P-type heavily doped diffusion layers to be a source or a drain of the P-channel transistor are formed using the gate electrode of the P-channel transistor as a mask. Then, a third thermal treatment is conducted to the P-type heavily doped diffusion layers at a lower temperature than that of the second thermal treatment.

In a pulse wave velocity measurement device (10), reference times (T1, T2) for an ejection wave component (S1) and a reflected component (S2) of a pulse wave S are detected by a reference time detection unit (2), and amplitudes (W1, W2) of the pulse wave (S) that correspond to the reference times (T1, T2) for the ejection wave component (S1) and the reflected wave component (S2) are detected by a pulse wave amplitude detection unit (3). A pulse wave velocity detection unit (5) finds a velocity (PWV1) of the pulse wave (S) on basis of the reference times (T1, T2) for the ejection wave component (S1) and the reflected wave component (S2) and the amplitudes (W1, W2) of the pulse wave (S) that correspond to the reference times (T1, T2) for the ejection wave component (S1) and the reflected wave component (S2). Thus the pulse wave velocity can be measured with high accuracy in consideration of a difference between the pulse wave velocities of the ejection wave and the reflected wave which difference is caused by a difference between the amplitude of the ejection wave component (S1) and the amplitude of the reflected wave component (S2).

摘要:
In a silicon layer formed on an insulator layer, a lattice defect region is formed to be adjacent to a channel region and source/drain regions, and the lower part of the channel region functions as a high-concentration channel region. The holes of hole-electron pairs generated in the channel region are eliminated by recombination in the lattice defect region, thereby suppressing the bipolar operation resulting from the accumulation of holes and increasing the source/drain breakdown voltage. The threshold value of a parasitic transistor is increased by the high-concentration channel region so as to reduce the leakage current in the OFF state. Alternatively, the holes may be moved to the source region to disappear therein by providing, instead of the lattice defect region, a high-concentration diffusion layer constituting and operating as a pn diode between the channel and source regions. Thus, it is possible to provide an SOI transistor causing no decrease in the source/drain breakdown voltage resulting from substrate floating effects and causing little OFF leakage current because of the activation of the parasitic transistor.
摘要:
The nonvolatile semiconductor memory device of the present invention includes: a semiconductor substrate having a surface including a first surface region at a first level, a second surface region at a second level lower than the first level, and a step side region linking the first surface region and the second surface region together; a channel region formed in the first surface region of the semiconductor substrate; a source region and a drain region which are formed in the surface of the semiconductor substrate so as to interpose the channel region therebetween; a first insulating film formed on the surface of the semiconductor substrate; a floating gate formed on the first insulating film; a second insulating film formed on the floating gate; and a control gate which is capacitively coupled to the floating gate via the second insulating film. The drain region includes a low-concentration impurity layer which is formed in the second surface region and which has one end extending toward the step side region, and a high-concentration impurity layer which is connected to the low-concentration impurity layer and which is formed in a region distant from the channel region. As impurity concentration of the low-concentration impurity layer is lower than an impurity concentration of the high-concentration impurity layer. The floating gate covers the step side region and at least a part of the low-concentration impurity layer via the first insulating film.
摘要:
In a semiconductor substrate having a surface including a first surface region at a first level, a second surface region at a second level lower than the first level, and a step side region linking the first surface region and the second surface region together, a channel region has a triple structure. Thus, a high electric field is formed in a corner portion between the step side region and the second surface region and in the vicinity thereof. A high electric field is also formed in the first surface region. As a result, the efficiency, with which electrons are injected into a floating gate, is considerably increased.
