Abstract:
Provided are semiconductor packages having immunity against a void due to an adhesive material and methods of fabricating the same. The semiconductor packages and the methods of fabricating the same can eliminate voids between package bodies to minimize delamination of the package bodies from the semiconductor package during the life time of semiconductor devices. To this end, a circuit substrate, a controller, and package bodies may be prepared. Each of the package bodies may have a package substrate, an adhesive pattern, and a package insulating layer. The package insulating layer may be formed on the package substrate to surround the adhesive pattern. The package bodies may be formed between the controller and the circuit substrate and contact the controller and the circuit substrate.
Abstract:
A stacked package includes a printed circuit board (PCB), a plurality of semiconductor chips, plugs and a controller. The semiconductor chips are sequentially stacked on the PCB. The plugs electrically connect each of the semiconductor chips to the PCB. The controller is disposed in any one of the semiconductor chips. The controller is electrically coupled to the plugs. Thus, the controller may be built in the semiconductor chip by a separate process so that a mechanical impact generated in a process for bonding the controller is not applied to the semiconductor chips. Further, a mechanical impact applied to the controller, which is generated in a process for forming a protection member, may be reduced.

Abstract:
A method of searching for a host in a network using IPv4 network comprises the steps of requesting host information, including link-layer address information and IP address information about an IP to be searched for, by sending a Neighbor Solicitation (NS) packet in which the IP to be searched for is set in an ICMPv6 target address to the network, after sending the NS packet, waiting for a predetermined time by taking a processing speed of a host and a transfer rate according to a network environment and state into consideration, after the predetermined time of waiting, determining whether a Neighbor Advertisement (NA) packet of the IP to be searched for has been received, and if, as a result of the determination, the NA packet of the IP to be searched for is determined to have been received, acquiring the host information from the NA packet.
Abstract:
Disclosed herein is a ball grid array (BGA) package stack that is not limited by ball arrangement because it utilizes a foldable circuit substrate, which permits interconnection between upper and lower individual BGA packages. The foldable circuit substrate has three portions. By bending the middle second portion, the foldable circuit substrate is folded in two. In the lower BGA package, an IC chip is attached on and electrically connected to a top surface of the first portion, and external connection terminals such as solder balls are formed on a bottom surface of the first portion. The top surface of the first portion is covered with a molding resin to protect the chip, and the third portion is placed on an upper surface of the molding resin. The upper BGA package is constructed in a similar manner to the lower BGA package as described above. For stacking, the interconnection terminals of the upper BGA package are joined and electrically connected to the third portion of the foldable circuit substrate of the lower BGA package.

Abstract:
An LCD device provides enhanced display quality. An insulating layer is formed on a first substrate. The insulating layer covers the contact portion of a switching device in which the switching device is electrically connected to a transparent electrode and has an opening for exposing a portion of the transparent electrode. A reflection electrode is electrically connected to the transparent electrode through the opening. The insulation layer covers a first portion of a driving circuit formed on the first substrate. A sealant is interposed between the first and second substrate to engage the first and second substrate and to cover a second portion of the driving circuit. Therefore, the driver circuit may operate normally, and the distortion of the signal outputted from the driver circuit may be prevented.
