20110097553 | TRENCH SUBSTRATE AND METHOD OF FABRICATING THE SAME - Disclosed is a trench substrate, which includes a first insulating layer having trenches formed therein, a second insulating layer disposed on a lower surface of the first insulating layer and having laser processability inferior to that of the first insulating layer, and a negative pattern formed in the trenches, and in which the second insulating layer having laser processability inferior to that of the first insulating layer functions as a stopper, so that the trenches having the same shape are formed in the first insulating layer, thus enabling the formation of a fine and uniform circuit pattern. A method of fabricating the trench substrate is also provided. | 04-28-2011 |
20120003793 | METHOD FOR MANUFACTURING EMBEDDED SUBSTRATE - A method for manufacturing an embedded substrate is disclosed. The method for manufacturing an embedded substrate, which includes a core substrate formed with a pattern on both surfaces thereof and formed with a cavity penetrating from an upper part thereof to a lower part thereof, a chip embedded in the cavity, and a first insulator and a second insulator provided respectively on either surface of the core substrate so as to protect the pattern, includes: preparing the core substrate; laminating the first insulator on a lower surface of the core substrate so as to cover a lower side of the cavity; forming an adhesive layer on the first insulator that is exposed through the cavity; embedding the chip in the cavity by attaching the chip on the adhesive layer; and laminating the second insulator on an upper surface of the core substrate. | 01-05-2012 |
20120298412 | PRINTED CIRCUIT BOARD AND METHOD OF MANUFACTURING THE SAME - Disclosed herein are a printed circuit board and a method of manufacturing the same. The method of manufacturing a printed circuit board includes: preparing a base substrate having first circuit layers formed on one surface or both surfaces thereof; forming a plating resist having openings for a first via layer on the base substrate; forming first via layers in the openings for a first via layer; forming insulating layers having outer metal layers on the base substrate having the first via layers formed thereon; forming openings for a second via layer over the first via layer on the insulating layers and the outer metal layers; and completing multi-layer vias by forming second via layers in the openings. | 11-29-2012 |
20120312591 | Printed Circuit Board and Method of Manufacturing the Same - Disclosed herein is a printed circuit board including: an insulating layer including a stopper layer for trench formation disposed in an inner portion thereof and trenches formed to expose the stopper layer for trench formation; and circuit patterns formed in the trenches. | 12-13-2012 |
