Title: Method for bonding conductive members in semiconductor package
Inventor: HUANG CHIEN-PING
IPC: H01L21/60
Filed: 2002-05-16
Granted: 2003-10-21
Abstract: A method for bonding conductive members in a semiconductor package is proposed. First, a chip carrier mounted with a chip is prepared, and defined with a power plate attach area and a ground plate attach area without interfering with chip-bonding for the chip carrier. The chip is formed with a power plane corresponding in position to the power plate attach area, and a ground plane corresponding in position to the ground plate attach area. Then, a plurality of metal bumps are bonded to the power plane and ground plane of the chip, and to the power plate attach area and ground plate attach area of the chip carrier. Subsequently, a plurality of conductive members (such as a power plate and a ground plate) are prepared, with a metal layer being formed respectively on the conductive members at positions corresponding to the power plane, ground plane, power plate attach area and ground plate attach area. Finally, a thermo-compression or solder-reflowing process is performed for bonding the metal layers to the metal bumps by forming of eutectic junction, so as to allow the conductive members to be electrically coupled to the chip and the chip carrier. As the eutectic junction is low in electrical resistance without adversely affecting velocity of electrical current, thereby preventing electrical failure from occurrence. Moreover, forming of the eutectic junction, instead of using a conductive adhesive, would more effectively reduce delamination and help increase bondability between the conductive members and the chip or chip carrier.

Granted: 2005-08-21
Abstract: We disclose a new location management strategy in PCS network, called multiple-level pointer forwarding with caching strategy. By associating the merits of the multiple-level pointer forwarding strategy and the caching strategy, we can reduce amounts of the location move cost and find cost of the system simultaneously. By the design of the multiple-level pointer forwarding strategy, we divide the setting up pointer forwarding into N stages. Utilizing the pointer forwarding between VLRs as ""the system location update operation"" can effectively reduce the user's location move and registration cost. Secondly, exercising the merits of the caching strategy and user profile will form a distributed system for location management. Meanwhile, the new algorithms of the move and find operation can become the PCS network to an intelligent network which can dynamically detect the user's most frequent registration areas during the current period. So system can get the spatial locality of user's movement path, which is as the criterion of the input system parameters. We integrate the multiple-level pointer forwarding strategy, the caching strategy and user profile strategy into a new location management strategy, the multiple-level pointer forwarding strategy with caching strategy, which can arrival to optimal usage the limited bandwidth of PCS network and to provide various services to all users on the move. Experiment prove our strategy can reduce greatly the location move cost and find cost than other location management strategies and to improve the effectiveness of location management in PCS network.
