Abstract: PURPOSE: An optical information processing apparatus is provided to improve a record quality or a record density by varying a numeric aperture of an objective lens at recording and reproducing. CONSTITUTION: An optical information processing apparatus comprises a diffraction screen(1-8) and a lambda/4 plate(1-7). Light incident from a semiconductor laser(1-1) penetrates the diffraction screen(1-8), thus a numerical aperture(NA1) of a coming path is determined by an objective lens holder(106). As a reflection light from an optical disk penetrates the lambda/4 plate(1-7) two times, the light of a center portion(no screen portion) of the diffraction screen(1-8) is penetrated and the light of the screen portion thereof is diffracted. A numerical aperture(NA2) of a going path is determined by the diffraction screen(1-8). The NA2 is more than the NA1.

Abstract: PURPOSE: A method for manufacturing a high voltage device is provided to realize a high voltage device over 25V by varying a process condition. CONSTITUTION: An impurity ion is implanted on a front surface of a structure to form a source and a drain(9) on the first drift region(3). The impurity ion is selectively implanted on a substrate91) and forms a high density drift region which is separated from the substrate(1) by as far as a predetermined distance. A gate and a gate side wall(8) are formed on the substrate which is a distanced region of the high density drift region. By using an implanted process which uses the gate and the gate side wall(8) as an ion implanting mask, a low density drift region is formed on a lower part of the high density drift region. An impurity ion is implanted to an upper side of the high density drift region to form the source and the drain in due order. Since there is a density difference between the upper side and the lower side of the drift region, a break down voltage is upraised, resulting in capability of operating in a voltage of 25V.
