  • Patent number: 6375062
    Abstract: A solder bumping method and structure for fine solder bump pitches. The method makes use of a semiconductor device having an input/output pad whose surface is provided with a solderable metal layer that serves as the UBM of the solder bump. A sacrificial layer is formed on the surface of the device to surround the metal layer. A plating seed layer is then formed on the metal layer and the surrounding surface of the sacrificial layer, after which a mask is formed on the seed layer and a via is defined in the mask to expose portions of the seed layer overlying the metal layer and the sacrificial layer. A solder material is deposited on the seed layer exposed within the via. The mask is then removed, followed by removal of a portion of the seed layer that is not covered by the solder material, leaving intact that portion of the seed layer beneath the solder material.

  • Patent number: 6371250
    Abstract: An ABS brake system employs two axially slidable brake discs and four brake pads that are biased to have floating light random contact therebetween in the off brake position. The ABS controller operates the brake pads with about one half of the usual brake pressure and about double the number of the usual braking and release cycles. The floating axially slidable brake discs and four brake pads have reduced residual torque drag during the brake release cycle and have reduced hystersis. The result is operation at a higher frequency and with less amplitude, than the usual sliding caliper and fixed brake system, and a resolution of a modulating scale for cycling that is usually associated with a much lower coefficient of friction surface than is actually present.

  • Patent number: 6373363
    Abstract: An actuator (10) for a fuel injector having a dual coil solenoid. The solenoid coils (14, 16) are connected in parallel and have windings that are wound in opposite directions. The actuator (10) of the present invention defines three air gap surfaces (22, 24, 26), one of which (24) is located in the space shared between the two coils (14, 16). The shared air gap surface (24) has a high flux density due to the additive nature of the magnetic forces between the oppositely wound coils (4, 16). The dual-coil solenoid of the actuator (10) of the present invention creates a very high force and a low inductive load which results in fast injector response times.
