A manufacturing method of a thin film semiconductor substrate includes implanting ions at a specified depth into a semiconductor substrate, forming a bubble layer in the semiconductor substrate by vaporizing the ions through heating, bonding an insulating substrate onto the semiconductor substrate, and cleaving the semiconductor substrate along the bubble layer to form a semiconductor thin film on a side of the insulating substrate. At the forming, the semiconductor substrate is heated at a temperature in a temperature range of approximately 1000° C. to 1200° C. for a duration in a range of approximately 10 μs to 100 ms. The heating of the semiconductor substrate is performed by using, for example, a light beam.

摘要:
A crystal resonator comprises a first vibrating region provided on a crystal wafer, a second vibrating region provided on the crystal wafer, the second vibrating region having a different thickness and positive/negative orientation of the X-axis from those of the first vibrating region, and excitation electrodes which are provided respectively on the first vibrating region and the second vibrating region for causing the vibrating regions to vibrate independently. Frequencies that change by different amounts from each other relative to a temperature change can be retrieved from one vibrating region and the other vibrating region. Thus, based on an oscillating frequency of the vibrating region in which a clear frequency change occurs relative to the temperature, the oscillating frequency of the other vibrating region can be controlled. Thereby, increases in the complexity of the crystal oscillator can be suppressed.

摘要:
Even when a module constituting a multi-module becomes an unavailable module, transfer of substrates can be promptly performed, while restricting generation of inferior products. When a destination module of a multi-module becomes unavailable before a substrate is transferred to the destination module, a destination of the substrate is changed to a module to which a substrate subsequent to the substrate is to be loaded. Upon generation of an unavailable module, before the transfer unit accesses the module on an upstream end of the transfer cycle, the transfer cycle proceeds until a precedent substrate becomes ready to be unloaded from the changed destination module. Alternatively, upon generation of an unavailable module, when the transfer unit is located on an upstream side of the unavailable module in the transfer cycle, the transfer operation of the transfer unit is made standby until a precedent substrate becomes ready to be unloaded in the changed destination module.
摘要:
To assuredly determine whether a shutter pinches a disk in a disk device including a shutter at a disk insertion slot. A shutter control device 10 includes a pinch determining unit 14 that determines whether the disk is pinched by the shutter based on a position of the shutter during a process of closing the shutter, and a sensitivity changing unit that sets sensitivity of determination to be high as ambient temperature of a shutter driving mechanism increases.
摘要:
A wavelength displacement correcting system and method where a monochromatic beam from an LED is incident through an incident slit of a spectral device and is diffracted on a diffraction grating to form a dispersed light image. Information relating to the dispersed light image is outputted and a wavelength displacement is calculated, using a forward voltage value corresponding to the constant current, and a forward voltage initial value. Wavelength displacement amounts of at least two diffracted beams are calculated, using output values of the at least two diffracted beams, and diffracted beam output initial values with respect to the dispersed light image. A dispersion width is calculated, using the calculated wavelength displacement amount of the beam, and the calculated wavelength displacement amounts of at least two diffracted beams.

摘要:
An uppermost one of multilayered electrode pads, on which a bump and a plating coat will be formed, is made of metal having high ionization tendency, particularly, Al. On the other hand, an uppermost one of multilayered electrode pads, on which none of the bump and the plating coat will be formed, is made of metal having low ionization tendency, particularly, Cu.
