Abstract: Disclosed herein an exposure apparatus capable of implementing a microfabrication onto a work with a higher throughput and a lower cost. The exposure apparatus generates interfering light by crossing two or more branched light beams branched from output light from a coherent light source at a predetermined interfering angle, and exposes the substrate by repeating an irradiation onto the substrate with the interfering light and a conveyance of the substrate. At this moment, the exposure apparatus shapes in interfering light irradiation region on the substrate onto which the interfering light is irradiated into a predetermined shape. Then, the exposure apparatus disposes a plurality of the interfering light irradiation regions in successive shots to be located adjacent to each other on the substrate in a direction of conveying the substrate without the interfering light irradiation regions being overlapped when exposing the substrate while conveying the substrate in a stepwise manner.

Abstract: A semiconductor device, encapsulated in a wafer level chip size package (WLCSP), includes a plurality of pad electrodes formed on the surface of a semiconductor chip, wherein a first insulating layer is formed on the surface of the semiconductor chip except the pad electrodes; a plurality of connection electrodes and at least one heat-dissipation electrode are formed on the surface of the first insulating layer; the pad electrodes and the connection electrodes are mutually connected via a first wiring portion; the heat-dissipation electrode is connected with a second wiring portion; and a second insulating layer is formed to enclose the electrodes and wiring portions, wherein the second wiring portion is arranged in proximity to a heating portion of the semiconductor chip and is formed on the surface of the first insulating layer except the prescribed region corresponding to the first wiring portion.

Abstract: An optical disk recording apparatus operates on an optical disk having circular tracks which are provisionally written with an index signal used for securing a constant linear velocity of the optical disk from an innermost circular track to an outermost circular track, and records data along the circular tracks at different linear densities on different annular zones of the optical disk. In the apparatus, a disk drive section rotates the optical disk while synchronizing the index signal successively read from the rotated optical disk with a predetermined reference clock signal to thereby maintain the constant linear velocity of the circular tracks. A clock generating section multiples or divides the reference clock signal by different rates to generate different writing clock signals in correspondence to the different annular zones of the optical disk.
