Modular bonding pad structure and method
View Patent ↗A semiconductor die includes a plurality of drivers and a plurality of bonding pads. Each driver is formed by a plurality of interconnected modules and has an associated bonding pad to which at least one of the modules of the driver is electrically connected. The modules of some of the drivers are positioned outside of the associated bonding pad toward a periphery of the die. The bonding pads may be arranged, for example, in a double- or triple-staggered pattern around the periphery of the die.
1. A method of forming bonding pads on a semiconductor die having a periphery, the method comprising:
forming a plurality of drivers on the semiconductor die, each driver including a plurality of individual modules; and
forming a plurality of bonding pads on the semiconductor die, at least some of the bonding pads being positioned between adjacent modules of an associated driver, wherein forming the plurality of drivers includes for at least some of the drivers forming conductive traces underlying the associated bonding pad to interconnect the modules of these drivers.
2. The method of claim 1 wherein forming a plurality of bonding pads on the semiconductor die comprises forming the plurality of bonding pads around a periphery of the semiconductor die.
3. The method of claim 2 wherein each driver includes N modules and wherein the method further comprises staggering each bonding pad relative to adjacent bonding pads to form an N-staggered pattern around the periphery of the semiconductor die.
4. The method of claim 1 wherein forming the plurality of bonding pads comprises forming each bonding pad partially overlying a module of an adjacent driver.
