Title: Package structure of dual die stack
Inventor: WANG SUNG-FEI
IPC: H01L25/065
Filed: 2001-03-01
Granted: 2002-03-11
Abstract: The present invention relates to a package structure of dual die stack which comprises: a substrate, a first die, a second die and a middle sandwiched sheet. The first die is bonded to the substrate, the second die has two opposed side edges, each having a first length. The middle sandwiched sheet is disposed between the first die and the second die, and is fixed and connected to the first die and the second die by adhesives. The middle sandwiched sheet has two opposed side edges corresponding to both side edges of the second die, each having a second length and the second length is longer than the first length, so that the flash area formed by the adhesive between the middle sandwiched sheet and the second die is exposed. The inspection instrument can thus inspect the size of the flash area between the middle sandwiched sheet and the second die or the thickness of the adhesive layer, so as to control the packaging quality, increase the bonding strength between the second die and the middle sandwiched sheet and thereby raise the reliability of the package product.

Title: Portable terminal
Inventor: NAKAMURA MASATAKE
IPC: G08G1/123
Filed: 2001-10-19
Granted: 2005-09-11
Abstract: When in an abnormal report the operation-portion of a portable terminal is operated (S1), an abnormal signal containing the information of the current position is sent to a center-device (S3). Then even if the power-supply switch is operated (S6), the non-action state can't be transferred in (No of S7) if in an abnormal state. Therefore, the center-device can continuously supervise the current position. If the portable terminal is lost, an operation-stop signal from the center-device is sent to the portable terminal. If the portable terminal receives said signal (S4), said portable terminal will be in an operation-stop state (S5). Then, even if the operation-portion of the portable terminal is operated (Y of S1), the sending-processing (S3) of the abnormal signal can't be performed due to the operation-stop state (Y of S2). Thus an ineffective abnormal signal can't be sent to the center-device.

Title: A cellular radio communication system with frequency reuse
Inventor: DAHLMAN ERIK
IPC: H04B7/26
Filed: 2002-04-02
Granted: 2004-04-11
Abstract: Different frequency reuse values are associated with different channels, e.g., different types of channels in a cellular communications system. For a high speed downlink shared type of channel, the frequency reuse may be greater than one in order to achieve higher data rates. On the other hand, the frequency reuse may be set to one for other channel types, e.g., dedicated channels including both uplink and downlink dedicated channels. Alternatively, the frequency reuse may also be set greater than one for channels in addition to the downlink shared channel, e.g., one or more dedicated downlink channels, while a frequency reuse of one is deployed for one or more uplink dedicated channels. Using different frequency reuse values reduces inter-cell interference, particularly at cell borders, while still maintaining existing soft handover schemes for dedicated channels if one or more of the channels is a code division multiple access (CDMA) type of channel.

As a result the recognition accuracy of the recognition camera is improved, and furthermore, the accuracy of the wire bonding in the order of mum is also improved.

Filed: 2002-08-06
Granted: 2004-06-21
Abstract: An aqueous solution containing sulfuric acid and hydrogen peroxide is used for a soft etchant in a soft etching step in a smear removing process performed prior to a catalyst applying process for chemical copper plating after formation of via holes (13) through an insulating layer (12) of a multi-layer substrate by irradiation of laser. The concentration of sulfuric acid is 1.4 times or less higher than the concentration of hydrogen peroxide. Preferably, the concentration of sulfuric acid is in a range of 5 to 50 g/l, and the concentration of sulfuric acid is lower than the concentration of hydrogen peroxide. More preferably, the concentration of sulfuric acid is in a range of 5 to 10 g/l, and the concentration of hydrogen peroxide is in a range of 30 to 35 g/l. As a result, smear can be certainly removed without excessively etching a conductive layer (11a) in the smear removing process.
