    摘要: An optical pick-up apparatus for reading and/or writing information from and/or on an optical record medium including a semiconductor laser, an objective lens projecting a laser beam onto the optical record medium, a hologram optical element having a first hologram for diffracting the laser beam onto a first pair of photodetectors to derive a focusing error and a second hologram for diffracting the laser beam onto a second pair of photodetectors to derive a tracking error. Each of the photodetectors of the second pair has light receiving regions which are divided along a division line substantially parallel with a diffracting direction of the second hologram which introduces astigmatism into the diffracted beams. A large tracking error signal can be detected stably on the basis of a distribution of an amount of light in a far field by the push-pull method.

    摘要: A semiconductor device in which low voltage elements and high voltage elements are formed on the same substrate. To simplify the manufacturing process of semiconductor devices and to improve the punch through voltage resistance between elements, when high voltage elements and low voltage elements are formed on the same semiconductor substrate, during the process for injecting p-type impurity into semiconductor substrate in the low voltage sections, at first a mask pattern having openings above the low voltage sections and openings above the element separating areas of the high voltage sections is formed, then p-type impurity is injected into the semiconductor substrate from above the mask pattern, followed by heat-treatment of the semiconductor substrate to diffuse p-type impurity into the semiconductor substrate. Thereby, channel stop diffusion layers comprising p-type impurity layer are formed under the element separating areas formed in the high voltage sections.

    摘要: An ellipsometer has a nonpolarization beam splitter (18) for dividing reflected light (17) from an object to be measured (16) into portions traveling along first and second optical paths (18a, 18b), an analyzer (19) for passing the polarized light component in a reference direction of the reflected light portion traveling along the first optical path, and a polarization beam splitter (20) for dividing the reflected light portion traveling along the second optical path into two polarized light components in different directions with respect to the reference direction. The light beams passing through the analyzer (19) and polarization beam splitter (20) are sensed by first, second and third photodetectors (21a, 21b, 21c), respectively. In a coating thickness control method, first and second ellipsometers (35a, 35b) are placed before and after a coating apparatus (36) provided along the transport path of a belt-like plate to be coated (31). A first ellipsoparameter (.DELTA.1,.psi.1) for the surface of the plate before coating is obtained with the first ellipsometer (35a). A second ellipsoparameter (.DELTA.2,.psi.2) for the surface of the plate after coating is obtained with the second ellipsometer (35b). The coating apparatus (36) controls the coating thickness (d) based on the difference between the first and second ellipsoparameters.

    摘要: A focus error detecting apparatus in which a light emitting and receiving element including a light emitting portion and light receiving portions all of which are formed in a common semiconductor substrate, a hologram element diffracts a light beam reflected by an object to generate plus and minus first-order diffraction light beams and to introduce an astigmatism into the plus and minus first-order diffraction light beams such that shapes of spots of the diffraction light beams formed on the light receiving portions of the light emitting and receiving element vary into substantially reverse directions to each other, and a focusing condition is detected in accordance with outputs of the light receiving portions. Therefore, in this apparatus, positioning adjustment of the light receiving portions with respect to the light emitting portion is not necessary, and thus a number of the adjusting process can be remarkably decreased and the cost for manufacturing the apparatus can be reduced. Furthermore, the focusing condition can be detected with high accuracy.

    摘要: This invention provides a technique of easily encoding image data to generate encoded data having high image quality within a target code amount using a small memory capacity by image encoding processing of performing frequency transform and quantization of each pixel block. A frequency transform unit separates image data into low frequency band data and high frequency band data. A coefficient quantizing unit, coefficient encoder, and code amount controller operate to encode the high frequency band data within a predetermined amount. When the encoding processing of the high frequency band data has ended, the quantization parameter of the low frequency band data is set based on the generated code amount of the high frequency band data. A coefficient quantizing unit, coefficient encoder, code amount detector, and quantization parameter updating unit operate to encode the low frequency band data into codes within a low frequency band target code amount.
