    • The present invention relates to a method for forming a solder resist and a substrate for a package. According to one embodiment of the present invention, provided is the method for forming solder resist, which comprises the steps of: forming a first solder resist inner region by primarily coating, exposing, and developing a solder resist on a substrate on which a circuit pattern including an outer POP pad for mounting an upper package thereon and an inner chip pad for mounting an inner chip is formed, wherein the first solder resist inner region is formed on an inner region of the substrate on which an inner circuit pattern including the chip pad is formed; forming a plugged SR region which does not expose the substrate while exposing the entire upper surface of the chip pad by performing a laser ablation process on the first solder resist inner region; changing a surface roughness by performing a desmear process on a surface of the first solder resist inner region in which the plugged SR region is formed; and forming a second solder resist SMD region by secondarily coating, exposing, and developing the solder resist on the substrate after the desmear process, wherein the second solder resist SMD region covers an edge of the POP pad. Further, a substrate for a package is provided.

    • PURPOSE: An etching system and a method for forming a circuit pattern using the same are provided to directly form the circuit pattern with jetting an etchant on a copper substrate at a high speed, thereby simplifying a process and reducing cost for manufacturing a product. CONSTITUTION: An etching system includes a computer aided design/computer aided manufacturing (CAD/CAM) master (210), a head part (220), a head part driving unit (230), an etchant jetting nozzle (240), and an etchant storage tank (250). The CAD/CAM master designates an etching parameter, and prepares design data for a circuit pattern predetermined by a user. The head part moves on a substrate according to the design data. The head part driving unit provides the head part with a driving force. The etchant jetting nozzle jets an etchant according to the movement of the head part. The etchant storage tank feeds the etchant inside the same to the etchant jetting nozzle. [Reference numerals] (210) CAD/CAM master; (230) Head part driving unit; (250) Etchant storage tank
