Abstract:
A method for positioning bond pads along an edge of a semiconductor die from a die corner, the method comprising the steps of:setting a baseline pad pitch to a first value; setting a first pad position equal to a first pad value; providing a focal point; determining a first angle between a first line through a center of the first pad position and the focal point and a second line through a center of the semiconductor die and normal to the edge; determining a first pad spacing increment value equal to the first value divided by a cosine of the first angle; setting a second pad position equal to a second pad value, wherein the second pad value at least equals the first pad value plus the first value if both of a first bond pad and a second bond pad are ground pads or power pads with the same potential, else the second pad value at least equals the first pad value plus the first pad spacing increment value; and using the first and second pad values to respectively position a first bond pad and a second bond pad along the edge of the semiconductor die.
