摘要: A semiconductor device (10) has a lead-on-chip (LOC) configuration. Leads (24) of the have central portions (36) which are electrically coupled to peripheral bond pads (14) by conductive wires (30). Inner (38) leads extend from toward centerline A--A for improved adhesion and provide an internal clamping area (41) stabilizes during wire bonding. In one embodiment, tie bar (22) leadframe (16) is used distribute power across chip (12). The may also include alignment features (50) tape (52) align (12) insulating (18) leadframe, respectively.
