Title: Method for producing wire connections on semiconductor chips
Inventor: EGGER HANS
IPC: B23K20/00
Filed: 1999-02-09
Granted: 2001-02-21
Abstract: On the production of wire connections (wire bonding) which start from a semiconductor chip and end on a substrate (2b) the capillary (12) guiding the wire (3) should be moved to an end section (s3) of its trajectory in a specific, programmed way in order to eliminate as far as possible reactions on the geometry of the wire bridge on bonding of the wire to the substrate and to produce flawless bond connections.

Title: Digital QAM modulator using post filtering carrier recombination
Inventor: ZHANG QIN
IPC: H04L27/36
Filed: 1999-02-26
Granted: 2000-08-11
Abstract: The efficient quadrature amplitude modulator of the present invention allows from 6 to 8 independent compressed channels to occupy a 6 MHz bandwidth while reducing processing power by 33 percent for 8 levels of modulation offered by 64-QAM and by 25 percent for 16 levels of modulation offered by 256-QAM. The modulator achieves this efficiency using an improved digital filter architecture combining the modulation and filtering with post filtering carrier combination. The QAM modulator presented is implemented with a reduction in the total number of binary parallel multipliers. To increase operational throughput, the speed of operation increases with the use of LUTs (look-up tables) storing precomputed filter weighting coefficients. The reduction in multipliers is also achieved by using post filtering carrier combination which similarly reduces the number of MAC operations performed during filtering. The invention can be construction either as a FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).
