Abstract: A semiconductor package includes a conductive pillar and a solder. The conductive pillar has a first sidewall and a second sidewall opposite to the first sidewall, wherein a height of the first sidewall is greater than a height of the second sidewall. The solder is disposed on and in direct contact with the conductive pillar, wherein the solder is hanging over the first sidewall and the second sidewall of conductive pillar.

Abstract: A Worldwide Interoperability for Microwave Access (WiMAX) integrated network server is disclosed. The WiMAX integrated network server is integrally includes an Access Service Network Gateway (ASN-GW), an Authentication Authorization Accounting (AAA) connected to the ASN-GW, and a Home Agent (HA). The ASN-GW follows the WiMAX standard, manages a mobile station connected to a base station, and provides connection paths connected to a network. The AAA authenticates the mobile station to be connected to the network. The HA provides a Mobile IP service to guarantee the mobility of the mobile station. The WiMAX integrated network server includes a separate data processing unit, which makes it possible to rapidly process data. The WiMAX integrated network server can independently manage communication among the mobile stations connected thereto, separately from an external network. The WiMAX integrated network server does not require additional equipment, which reduces the installation space and costs.
