ABSTRACT:
A semiconductor device is formed from a die and a lead frame having one or more bus bars. Portions of the bus bars are overlain with an electrically insulative material while leaving bonding areas unobstructed, whereby bond wires which span the bus bar(s) may be bonded with a shorter wire and a lower loop, without the danger of shorting to the bus bar(s). The incidence of harmful wire sweep in the encapsulation step is also reduced.
