Abstract:
A method of molding a semiconductor package includes coating liquid molding resin or disposing solid molding resin on a top surface of a semiconductor chip arranged on a substrate. The solid molding resin may include powdered molding resin or sheet-type molding resin. In a case where liquid molding resin is coated on the top surface of the semiconductor chip, the substrate is mounted between a lower molding and an upper molding, and then melted molding resin is filled in a space between the lower molding and the upper molding. In a case where the solid molding resin is disposed on the top surface of the semiconductor chip, the substrate is mounted on a lower mold and then the solid molding resin is heated and melts into liquid molding resin having flowability. An upper mold is mounted on the lower mold, and melted molding resin is filled in a space between the lower molding and the upper molding.
Abstract:
A programming method of a non-volatile memory device including a plurality of memory cells arranged in a plurality of cell strings includes sequentially applying a first pass voltage to unselected word lines of word lines connected to the plurality of memory cells during a first interval and a second pass voltage higher than the first pass voltage to the unselected word lines during a second interval; and applying a discharge voltage lower than a program voltage to a selected word line of the word lines connected to the plurality of memory cells after applying the program voltage to the selected word line in the first interval, and applying the program voltage to the selected word line during the second interval.
Abstract:
A printed circuit board (PCB) includes: a base substrate including a top surface including an electronic device mounting region; chip connection pads that are provided on the electronic device mounting region; a conductive pattern group that is provided on the top surface of the base substrate and includes an extended conductive pattern extending between two adjacent chip connection pads from among the chip connection pads, the extended conductive pattern being spaced apart from each of the two adjacent chip connection pads; and a solder resist layer that covers a part of the extended conductive pattern and is spaced apart from the chip connection pads.
Abstract:
A printed circuit board (PCB) comprises an internal wiring layer, an insulating layer on the internal wiring layer, a via hole extending through the insulating layer, and an external wiring layer on the insulating layer. The internal wiring layer comprises at least one metal wiring layer. The via hole exposes the internal wiring layer. The external wiring layer is electrically connected to the internal wiring layer. The external wiring layer includes a mounting area on which a semiconductor chip is disposed and a non-mounting area on which a semiconductor chip is not disposed. A thickness of the mounting area is less than a thickness of the non-mounting area.
