PROBLEM TO BE SOLVED: To facilitate the designing of an electric device formed on a semiconductor layer of a front surface in forming a thick portion, e.g. an optical waveguide on the semiconductor layer sandwiched by a double-layer insulator. SOLUTION: A dual SOI substrate 10 has a silicon layer 15, an insulation film (silicon oxide film) 14, a silicon layer 13 and an insulation film 12 in this order from the front surface side. The depth distribution of the upper insulation film 14 is made to be uniform and the depth distribution of the lower insulation film 12 is made not to be uniform, and a thick portion along a predetermined passage is formed on the silicon layer 13. The refractive index of Si is 3.5 and the refractive index of SiO 2 is 1.5. The thick portion of the silicon layer 13 is used a core and the insulation films 12, 14 corresponding to the thick portion are used as clads, and the optical waveguide 16 along the predetermined passage is formed. In this way, since the thickness of the silicon layer 15 on the front surface side is uniform and characteristics of MOS devices formed on each portion of the silicon layer 13 can be matched easily, and the designing of the electric device is facilitated as a whole.

PROBLEM TO BE SOLVED: To provide a spherical aberration correction apparatus, a spherical aberration correction method, and an optical disk apparatus in which correction of spherical aberration can be performed at high speed without depending on a temperature condition. SOLUTION: When a signal applied to a spherical aberration correction element using liquid crystal is switched from a first signal of first peak voltage to a second signal of second peak voltage being larger than the first peak voltage, it is passed through an intermediate signal. And a response time of the spherical aberration correction element can be held at an appropriate state without depending on a temperature condition by adjusting at least either of peak voltage of this intermediate signal and an applied time based on the spherical aberration correction element.

PROBLEM TO BE SOLVED: To secure the adhesive strength of a diaphragm for an ink-jet printer unit. SOLUTION: The diaphragm covering the pressure chamber has a thermoplastic layer with adhesiveness and a pattern layer which overlies the thermoplastic layer in at least the opposite section against the pressure chamber and at the position other than the opposite section against the above liquid feeding-passage. At the time of installing the diaphragm which has the thermoplastic layer and the pattern layer on the principal plane at which the liquid feeding-passage of the pressure chamber forming section is formed and of adhering the thermoplastic layer of the diaphragm onto the top of the pressure chamber forming section by pressurizing and heating the layer, the pressure is applied in concentrating to the pattern layer of the diaphragm. At that time, neither unnecessary pressure is applied to the opposite section against the liquid feeding-passage where the pattern layer is formed, nor the liquid feeding-passage is closed with the thermoplastic layer, and also the work of bonding the diaphragm to the pressure forming section at which the pressure chamber has been formed is easily performed.
