A device comprising a semiconductor chip (110) having a side edge (111) and a plurality of metal bond pads (120, 121) near the edge; the pads are aligned to form rows (130, 131) parallel to the edge. The device further includes a leadframe (100) having leads oriented with one end towards the chip edge and spaced from it by a gap (150); the chip is attached to the leadframe. Ends of selected leads are connected by a metal cross bar (160) parallel to the chip edge. Substantially parallel bond wires (170) are crossing the gap to connect each chip pad either to the crossbar or to a non-selected lead end. In a preferred lead arrangement, the selected leads alternate with non-selected leads.

An integrated circuit package includes an inductance loop formed from a connection of bonding wires and one or more input/output (I/O) package pins. In one embodiment, the inductance loop is formed from a first wire which connects a bonding pad on the integrated circuit chip to an I/O pin of the package and a second wire which connects the same bonding pad to the same pin. By forming the inductor loop within the limits of the integrated circuit package, a substantial reduction in space requirements is realized, which, in turn, promotes miniaturization.

An illuminated electric toothbrush comprising a light emitting diode emitting light having a flux density of at least about 30 mW/cm . An illuminated electric toothbrush having this level of flux density can result in an oral care benefit such as whitening. When this toothbrush is used within the oral cavity the heat generated by the toothbrush remains low enough that the surface temperature of the teeth remains below about 43 °C. The flux density of at least about 30 MW/CM can be achieved by overpowering the light emitting diode, by using a light emitting diode having at least about two dices, and by providing a pulsed or non-continuous current to the LED which results in a pulsing or non-continuous light.
