Title: Method for decreasing the junction resistance of contact window
Inventor: LIN DA-CHENG
IPC: H01L21/28
Filed: 1999-04-06
Granted: 2000-12-21
Abstract: There is provided a method for decreasing the junction resistance of a contact window, which forms a thin native silicon oxide layer on the surface of the conductive layer used in the bottom of the contact window. First, diluted hydrofluoric acid is used to remove most portion of the silicon oxide layer. Next, the chip is placed in an ultra-vacuum system. Then, a thin polysilicon layer is formed on the silicon oxide layer. Subsequently, an annealing step is executed, so that the silicon oxide layer is reacted with the polysilicon layer to generate SiO gas for being exhausted, thereby entirely removing the silicon oxide layer. Next, a doped polysilicon layer is formed on the surface of the conductive layer at the bottom of the contact window, and then the chip is removed from the ultra-vacuum system. Again, the diluted hydrofluoric acid is used to remove possible native silicon oxide layer. Finally, another conductive layer is filled into the contact window thereby forming the manufacture of the contact window.

Title: Method for straightening profile steel while simultaneously minimizing the internal stresses thereof
Inventor: HARTUNG HANS GEORG
IPC: B21D3/00
Filed: 1999-05-27
Granted: 2001-05-16
Abstract: A method for straightening profile steels that can provide section steels with a high quality and low-residual stress, without using expensive devices required in traditional straightening device. A steel profile with maximum and minimum local cross-sectional temperatures respectively below the Ar1 point and above a lower limit temperature Iu is clamped at its ends and is cooled down. As a consequence of clamping, the lower limit temperature Iu produces a thermal dilatation in all profile fibers, which is greater than the dilatation, which would be required for fiber plasticizing of the non-clamped profile with the highest compressive residual stresses.

Title: Expanded smart card communication architecture and procedure for communicating between smart card application and data carrier
Inventor: HAMANN ERNST-MICHAEL
IPC: G06F21/34
Filed: 1999-06-15
Granted: 2001-09-01
Abstract: The present invention describes an improved communication architecture for smart card systems and an improved procedure for communication of the smart card applications using protected data carriers, particularly in the case where smart cards or smart card readers cannot be used. The improved communication architecture has a common virtual smart card interface between the respective smart card applications and the modules which facilitate access to the protected data carriers (smart cards). The modules allow access to either physical smart cards, virtual software smart cards or hardware smart cards. The common virtual smart card interface means that the application is completely independent of the respective module or the respective data carrier. Alternatively, the improved communication architecture additionally contains a virtual smart card adapter which communicates over the common virtual smart card interface with the respective smart card application. The different modules are attached to the smart card adapters and selected statically or dynamically over the smart card application. Virtual software smart cards which functionally imitate true physical smart cards can be linked over the virtual smart card adapter to communicate with a smart card application. This procedure is then particularly suited for when the smart card is lost or defective, the smart card reader cannot function, or for testing new smart card technologies.

Title: Apparatus and method for an integrated circuit having high Q reactive components
Inventor: ZAVREL ROBERT J JR
IPC: H05K3/46
Filed: 1999-12-22
Granted: 2002-02-01
Abstract: In an IC packaging scheme, a multilayer substrate is composed of electrically conductive layers of interconnects, separated by insulative layers of epoxy resin or ceramic and connected by vias. Passive elements are integrated within the substrate at the definition stage during layout of the interconnects. The passives can be used to enhance the electrical performance of the active circuit die to a maximum extent allowed by the material technology used for the substrate. Material selection for the package is made to allow for the best passive integration for a given circuit design. Typical applications include power supply bypass capacitors, radio frequency tuning, and impedance matching. The incorporation of passives in the packaging substrate creates a new class of electrically tailorable packaging that can derive improved performance for any given die design over existing approaches.

Title: Method and device to eliminate the deviation between the dense pattern and sparse pattern
Inventor: YE JIN-DE
IPC: H01L21/027
Filed: 2000-01-18
Granted: 2003-04-01
Abstract: A method to eliminate the deviation between the dense pattern and sparse pattern is disclosed, in which an attenuator is added between the photomask and image to reduce the light intensity passing through the sparse pattern on the photomask, so that the image-forming light intensity is the same as the light intensity passing through the dense pattern on the photomask, thereby eliminating the deviation due to the difference of light intensity between the dense pattern and sparse pattern during exposure. The design of attenuator comprises two regions between the photomask and image, one is the translucent region, and the other is the attenuation region. By coating one layer of material on the attenuator to reduce the transmitting light intensity, the response intensity of the low-frequency region is reduced, so that the response intensity of the high-frequency region and low-frequency region are the same.

Title: Flexible and highly efficient packet classification method
Inventor: LEU KUO-CHENG
IPC: H04L12/801
Filed: 2000-03-22
Granted: 2002-08-11
Abstract: The present invention relates to a type of flexible and highly efficient packet classification method where rules are stored in a format of rule mapping table instead of into the original rule database. The generation method of this rule mapping table is described as follows. Firstly, each input key is divided into several subkeys. One after the other, each combination of the subkeys is compared with the key in the same subkey field of each rule before, by means of bit mapping, storing the comparison result ('1' for 'Yes' and '0' for 'No') into the rule mapping table. In accordance with the present invention, it is very easy to support multiple rule databases or sub tables for storing multiple rule databases of different widths or lengths together in one search engine. Thus, the whole design becomes practically forwarding (high speed and small size) and flexible (including various rule databases). The present invention is also highly applicable in the design of network processor as a common search engine or when fast search is required. It may also be used as a content addressable memory (CAM) replacement technique.
