Abstract:
First, a unilayer wiring board is fabricated, which has wiring layers formed in desired shapes on both sides of an insulating base member; and a metal bump formed on the wiring layer on one side of the insulating base member. Then, a desired number of unilayer boards are prepared and stacked up. On that case, the board disposed in the uppermost layer is prepared without having a metal bump. The boards are positioned and stacked up in such a manner that a metal bump of one of adjacent boards is connected to a corresponding wiring layer of the other board. Thereafter, resin is filled into gaps between the stacked boards, and insulating layers are formed on both sides of a multilayer board obtained through the above steps, in such a manner as to cover the entire surface except pad areas defined at predetermined positions on the wiring layers.

A manufacturing method of a chip integrated substrate is disclosed. The manufacturing method includes a first step that forms a wiring structure to be connected to a semiconductor chip on a first core substrate; a second step that disposes the semiconductor chip on a second core substrate; and a third step that bonds the first core substrate on which the wiring structure is formed to the second core substrate on which the semiconductor chip is disposed. In addition, the manufacturing method includes a step that removes the first core substrate after the third step and a step that removes the second core substrate after the third step.
Abstract:
A digital content reproducing apparatus is provided with a plurality of user operation interfaces, e.g., a linear content operation panel and an interactive content operation panel, a data monitor unit monitors information on digital contents, and upon occurrence of a change, the plurality of user operation panels are automatically and exclusively displayed in an operation panel display area. Accordingly, only usable operation keys can be displayed, user operation learning time can be shortened, since the panel rendering area is made small, a mouse motion distance can be shortened, and easy to use can be improved. Further, since the panel rendering area is made small, the image display area can be made relatively large.
Abstract:
A video and audio recorder and a method of operating the same. The recorder includes a TV signal receiving unit, a video/audio compression recording control unit for compressing the video and audio signals and outputting a compressed video/audio multiplex data at the time of recording a program, an accumulation recording unit for recording the compressed video/audio multiplex data in a recording medium, and a recording control unit for controlling the video/audio compression recording control unit thereby to control the program recording operation. The recording control unit, based on the program information of the program to be recorded, controls the program recording operation by setting proportion information between the video recording bit rate and the audio recording bit rate in the compression process of the video and audio signals in the video/audio compression recording control unit.
