Title: Flip chip semiconductor encapsulation with solder block pre-made on the substrate and method for producing the same
Inventor: WANG YU-BO
IPC: H01L23/28
Filed: 2001-08-30
Granted: 2002-11-11
Abstract: A method for producing a flip chip semiconductor encapsulation with a plurality of solder blocks pre-made on the substrate comprises: preparing a substrate pre-defined with a flip chip region where the surface of which is laid with a plurality of substrate solder pads thereon; using an electroplating process to form a plurality of copper solder blocks on the flip chip region to integrally connect to the substrate solder pads; and using an adhesive to bind a semiconductor chip, which is pre-made with a plurality of chip solder pads on the circuit face thereof, to the flip chip region so that the substrate and the chip are electrically connected through the copper solder blocks and the corresponding chip solder pads. The invented method can directly form a plurality of copper solder blocks on the substrate solder pads without a costly process, thereby greatly reducing the process complexity and thus the cost. Furthermore, a copper material is used to replace a conventional lead-tin alloy in the preparation of a flip chip solder block in order to avoid the occurrence of collapse, thereby avoiding the occurrence of an improper electric bridging due to an excessive outward expansion of adjacent solder blocks.

Title: Use of non-magnetic paths for an electronic module intended for a timepiece
Inventor: LEUBA FREDERIC
IPC: H02K3/04
Filed: 2002-02-22
Granted: 2002-12-11
Abstract: The present invention proposes improving the yield of a microgenerator (1) used for operating a timepiece. Such a microgenerator operates on the basis of the phenomenon of electromagnetic induction, it is thus desirable to limit as far as possible the presence of magnetic masses in proximity to said generator. Research undertaken has shown that the electrically conductive paths (9), and even their single protective layer, arranged in proximity to the microgenerator brake it, when they are formed of a magnetic material, and in particular a ferromagnetic material. Thus, the selection of exclusively non-magnetic materials is proposed for manufacturing the conductive paths.

Title: Signal correcting method and signal generating method
Inventor: SHIU JR-GANG
IPC: G11B7/085
Filed: 2002-04-01
Granted: 2003-12-01
Abstract: There is provided a radio frequency ripple zero cross signal correcting method for a compact disk transiting from following to seeking track, which utilizes the radio frequency ripple peak level in sampling the seeking tracks and the radio frequency ripple DC level in following the track, and uses the difference therebetween as the correcting value. The correcting value is used to correct the radio frequency ripple zero cross switching level, so as to obtain the correct radio frequency ripple zero cross signal in transiting from following to seeking the track. It is able to avoid distorting the radio frequency ripple zero cross signal due to transiting from following to seeking the track, which causes the radio frequency ripple zero cross signal to shift and results in an error in determining the moving speed of the optical pick up head and the track number, thereby effectively improving the searching efficiency of the compact disk and preventing the optical pick up head from out of control accidentally.

Title: Method for manufacturing a printed circuit board
Inventor: LEE SUNG-GUE
IPC: H05K3/06
Filed: 2002-07-18
Granted: 2003-09-01
Abstract: A printed circuit board (PCB) and method of forming same is performed without incoming lines for plating. The plating is preferably performed on ball pad areas and/or bonding pad areas being the top layer of a multi-layer PCB. A metal layer that later forms circuit patterns serves to supply a power for plating ball pads for solder-ball bonding and bonding pads for wire-bonding with gold (Au). Thus, the gold (Au)-plating is performed prior to forming the circuit patterns. A positive-type first photoresist is coated on the metal layer to form the ball pads and the bonding pads. The coated first photoresist is also used to form circuit patterns. The gold (Au)-plated metal layer of ball pad areas and the bonding pad areas are protected by a second photoresist, which is reactive with a larger quantity of light than the first photoresist. Both first and second photoresists can be concurrently developed.
