Web65µm fine-pitch wirebond pad specifications, but were placed at 110µm final pitch to aid in testing and failure analysis. The final die size was 6.45mm x 6.45mm. The test program was developed to determine continuity to each bond pad by sensing the drop across the pad protection diodes on each pin. Shorts between pads and/or WebThe bond pad structure 100 includes a lower conductive layer 110, an intermediate conductive layer 130, an upper conductive layer 140, dielectric layers 120 and 125, passivation layers 150 and 170, and a bond pad 160. The lower conductive layer 110 may be electrically connected to and/or be a portion of, an interconnect structure (e.g., an MLI).
WebRDLs are formed by adding passivation and metal layers on the top of the die, relocating the pads according to the design rules of the solder bumping process (Figure 5). This additional step, done as an optional part of the bumping process, can shorten cycle time and speed delivery of engineering samples. Web30 Mar 2001 · BACKGROUND OF THE INVENTION. 1.
