Abstract:
1. A semiconductor device, comprising: a semiconductor die comprising a plurality of first bond pads located along a periphery of the semiconductor die and a plurality of second bond pads located toward a center of the semiconductor die; a flex circuit comprising: a dielectric layer having a first side and a second side opposite the first side; a plurality of die bonding pads on the first surface of the dielectric layer which do not overlie a via which extends into a thickness of the flex circuit dielectric layer each die bonding pad having a first surface area; a plurality of direct connect pads on the first surface of the dielectric layer each direct connect pad has a second surface area, wherein the second surface area is larger than the first surface area; a plurality of blind vias, wherein each blind via is electrically coupled to one direct connect pad of the plurality of direct connect pads; a plurality of conductors, wherein each conductor is electrically coupled to one blind via of the plurality of blind vias; a plurality of via pads on the first surface of the dielectric layer, wherein each via pad has a surface area which is equal to the second surface area, each die bonding pad of the plurality of die bonding pads is electrically coupled to one of the via pads with an active trace and each of the first plurality of bond pads is electrically coupled to one of the plurality of die bonding pads on the first surface of the dielectric layer; each of the second plurality of bond pads is electrically coupled to one of the direct connect pads; and each of the direct connect pads is free from contact with one of the plurality of die bonding pads.
